Optical block replacementIf you are sending your optical block in for rebuilding, the rebuilders will likely request that you leave all parts on the optical block for testing purposes, so you should only disconnect the remaining wiring that connects the optical block to other parts of the TV.

If you are doing a direct replacement of your optical block with a purchased part, the purchased part likely will not have a projection lamp or power supply block on it, so you will have to remove those parts from your current optical block and install them on the replacement.Disconnecting wiring from power supply blockThis step may be optional, if the power supply block must be transferred to a purchased replacement optical block. Undo the blue plastic-coated wire holders to release the two wire bundles. Disconnect the connectors shown with the dotted lines in the photo below. One, which presumably provides power, is disconnected directly from the power supply block, and the other is a regular wire connector.

Here is a picture of a replacement optical block for the KF-60WE610. Note that the lamp and power supply block need to be removed from the old optical block and attached to the replacment.

In theory, blowing air over the LCD panels and other internal parts could move some dust. In addition, the glass on the projection lens can be cleaned with lens paper and solution. Aerosol (canned) air is not recommended, as it can come out very cold and/or spray moisture, so extreme care should be exercised when using it (do this at your own risk). More thorough cleaning can be accomplished by further disassembling the optical, as described below.

Optical block disassemblyThe method described below requires even more care and patience, particularly the points where the LCD ribbon cables and the light path filters are removed. However, it will allow much more thorough cleaning of the internal parts, as it enables direct access to the filters and LCD panels.Note that Paul Patience has created another web site (Sony LCD Projection TV Cleaning Instructions) that describes this process on a KF-42WE620. It includes instructions and photos on accessing and cleaning the individual LCD panels, prism faces, and filters inside the optical block. Also note that, on the KF-42WE620 (and perhaps all 2003 Grand WEGA or "WE" models), the locations of the blue and red LCD panels are swapped relative to the KDF-55WF655 (and perhaps all 2004 Grand WEGA or "WF" models).Remove the centrifugal lamp cooling fan. It is held by 3 silver-colored screws, as indicated in the photo below.

The following photos show the optical block with the lamp fan, lamp fan mounting plate, LCD panel cover, wedge-shaped piece, and projection lamp removed (note the that the blue and red LCD panel positions are reversed on some models):

Next, remove the portion of the optical block that contains the LCD panels, prism, and projection lens. It is held by four silver-colored and four black screws, as indicated in the photo below. Pull this unit off the rest of the optical block, while carefully monitoring the ribbon cables to make sure they do not get caught. Note that the clear dome on the projection lens appears to be made out of plastic.

The following photo shows the gaps between the LCD panels and the prism through which it is possible to clean the surfaces. DO NOT attempt to unscrew the LCD panels from the prism faces, or you will likely lose your convergence upon re-installation:

Your TV uses a projection lamp as its light source. As with any lamp, it has limited life and needs to be replaced when the Lamp indicator flashes or the screen becomes darker. Note the following: After turning on your TV, it may take a while (1 minute or less) before the picture appears. When the projection lamp wears out, the screen goes dark. Replace the lamp with a new Sony XL-5100 replacement lamp (not supplied). The light emitted from the lamp is quite bright when your TV i s in use. To avoid eye discomfort or injury, do not look into the light housing when the power is on.

Use a Sony XL-5100 replacement lamp (not supplied) for replacement. Use of any other lamp may damage the TV. Do not remove the lamp for any purpose other than replacement. Doing so may cause injury or fire. Do not put flammable materials and metal objects inside the lamp receptacle of the TV after removing the lamp. Doing so may cause fire or electrical shock. Do not touch the lamp receptable once the lamp has been removed. When the lamp eventually burns out, you may hear a noticeable “pop” sound. This is normal and it is inherent to this type of lamp. In rare instances, the bulb may pop inside the lamp unit, but the lamp unit is designed to contain all of the broken glass pieces inside the lamp unit. The lamps contain mercury. For proper disposal of the used lamps, follow and observe the local ordinances. See page 107.

The lamp is very hot after use. Never touch the glass portion of the lamp or the non-designated surrounding parts (shown in gray). After the used lamp has cooled, place it into the empty box of the replacement lamp. Never put the used lamp into a plastic bag.

Consult your Sony dealer for a Sony XL-5100 replacement lamp. Take great care when replacing the lamp or plugging in/unplugging the connecting cords. Rough handling may cause the TV t o fall, damaging the TV, the TV s tand and the floor. The used lamp

SAFETY CHECK-OUT ( US model only ) After correcting the original service problem, perfom the following safety checks before releasing the set to the customer: l. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors. 3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators. 4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 5. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recom mend their replacement. 6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 7. Check the condition of the monopole antenna (if any). Make sure the end is not broken off, and has the plastic cap on it. Point out the danger of impalement on a broken antenna to the customer, and recommend the antenna’s replacement. 8. Check the B+ and HV to see they are at the values specified. Make sure your instruments are accurate;be suspicious of your HV meter if sets always have low HV. 9. Check the antenna temminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

When the temperature sensor (for Ambient) on the S1 board detects high temperature or the temperature sensor (for Lamp) on the S2 board detects high temperature or the temperature sensor (for Panel) on the C board detects high temperature, the DE-micro (IC5) turns off the lamp.

Although the TV is made with high-precision technology, black dots may appear or bright points of light (red, blue, or green) may appear constantly on the screen. This is a structural property of the panel and is not a defect.

Your TV uses a projection lamp as its light source. It is time to replace the lamp with a new one (not supplied) when: • the lamp replacement indicator on the front panel blinks in red, • screen images become dark, • no image appears on the display after prolonged use. In rare instances, the bulb may pop inside the lamp unit, but the lamp unit is designed to contain all of broken glass pieces inside the lamp unit. (See “Replacing the Lamp” on page 104.) When the lamp eventually burns out, you may hear a noticeable pop sound. This is normal and is inherent in this type of lamp.

Replacement Parts When replacement parts are required, be sure the service technician certifies in writing that he has used replacement parts specified by the manufacturer that have the same characteristics as the original parts. Unauthorized substitutions may result in fire, electric shock or other hazards. See “Replacing the Lamp” on page 104.

Unregistered guestPosted on Saturday, February 18, 2006 - 22:07 GMTAnother yellow roadmap victim. Bought the 42" WEGA with limited 1 yr warranty. Roadmap appeared a few months after the warranty expired. Called Sony and had no success with the initial rep so asked for his supervisor. His supervisor transferred me to the 2nd level support. I faxed in my problem and got a call back from a fluent speaker. He said Sony will cover the Optic Block part for replacement. Then he recommended "Sony Authorized" servicers in my area that I needed to call to set up an appointment. Of course, the servicers they recommended wanted $500 JUST TO LOOK AT THE TV. I told Sony that I"ll shop for a cheaper servicer. He said that"s cool but make sure they are "Sony Authorized". So I found a servicer that would check my TV for $50. I made sure to ask them if they were "Sony Authorized". They said yes, they have dealt many Sony"s before. This is where I got screwed. They came out and looked at my TV for $50 and wrote an estimate. I faxed the estimate to Sony who told me that the servicer I chose was NOT IN THEIR SYSTEM. I told the sony rep that they are Sony Authorized. He said, they are not in our system as a SONY AUTHORIZED WARRANTY SERVICER. Big difference. So I ate the $50 and had to go with one of Sony"s recommended servicers who came out and checked my TV for $105 which would go toward the $400 labor charge. I faxed the estimate in and Sony ordered the new Optic Block. This is where I tried to fight even further. I complained a bit more to Sony about how $400 for labor is too much. After all, it wasn"t my fault that Sony"s Optic Block broke. So it went back and forth and finally I got them to pay 25% of the labor charge ($100). The servicer came out and replaced the part, I paid for the rest of the labor, and now my TV looks fine again. Bottom line: I paid $290, Sony paid $950. Lessons learned: 1.) be polite but persistent, and keep asking for supervisors when you aren"t satisfied. also tell Sony and your repair service about this forum; 2.) make sure your servicer is SONY AUTHORIZED WARRANTY SERVICER, and check with Sony first before someone comes out; 3.) get the extended warranty, it will be worth it because the technologies aren"t fully developed yet and there are still many problems with LCDs; 4.) take advantage of the Internet by spreading the knowledge about your problems through these forums, and add pictures too; 5.) get smart: tell people about your TV problems and ask about their experiences with different brands. you"ll be a smarter consumer; and 6.) be patient! One final note: when the repair guy was fixing my TV, he mentioned something about other type of problem with the WEGAs: the yellow haze, not roadmap. He said that if you smoke in your house, the smoke gets sucked into TV cooling fan and fogs up the optic lens. That"s why you get a hazy picture. No dealer or manufacturer will tell you about this potential hazard because they want your money. So if you smoke in your house and have one of these TVs...it"s something to think about. This is why forums such as these are cool because you can share these important bits of info. I am a smarter consumer because of this forum, thank you to all who have helped. For the rest of you who have problems, do your part and post something. Let"s all help each other save money!

Unregistered guestPosted on Tuesday, February 28, 2006 - 00:33 GMTI too am having problems with my sony KDF 42WEGA655. I did not purchase but received as a gift from my husband for Christmas 2004. The TV was to keep me company because of his many deployments. The PROBLEM: The TV would not display any video feed but with perfect sound.Every month or so the same thing. Each time I would tell myself I was going to call Sony the next day but by the next day I would turn the set on and it would be fine. Now this past weekend the picture will not come on at all. Just a lit up blank screen with sound. 13 or so months later I called Sony. Of course they gave me names of different service providers. I am so glad I found this forum to back me up that there seems to be a recurring problem with their LCD TV"s they are selling. I have talked to three customer service people so far and two have told me maybe Sony can help and cover what is wrong. I don"t know if they are just saying that to pacify me or if they will really help but after reading this forum I am certainly going to push for them to cover what I think is probably the optic block. Much to expensive to fix if they do not cover. There is obviously something wrong with the product or there would not be so many of the same complaints here on the forum. I will keep the forum posted on how this turns out because if they do not stand behind their product I think all of us together could have legal remedies available to us.

Registered: Mar-06Posted on Thursday, March 16, 2006 - 11:06 GMTJust starting this fiasco. I have a Sony KF-50WE610 purchased around 11/03. I have owned Sony products for years with no problems so I did not buy the extended warranty. About 2 weeks ago started to see the blue splotches. A repair tech is scheduled for Friday so I am hoping that cleaning the optical block will be all that is needed and not replacement. I just wanted to make a suggestion--since one of the earlier posts stated that Sony does not recognize forums such as these, has anyone/everyone filled out a complaint with the Better Business Bureau (http://www.bbb.org/) ? Maybe Sony will take notice if a flood of complaints comes through the BBB especially since Sony Corporation of America is a member of the BBB.

Registered: Mar-06Posted on Sunday, March 19, 2006 - 06:22 GMTMy KV32XBR400 (purchased in year 2000) worked great until the cable company started showing HDTV. My hallucination at this time, based on experience & member feedback here, is that the (separate?) power supply for HDTV picture runs too hot & cooks other local components. I did all the "reset" operations & exentually paid over $100 in labor and $300 for a Sony replacement "D-board". The new board failed within 2 days! Repair guy actually suggested I buy ANOTHER for $300 more. After some fancy screaming on my part, they generously replaced the board for only a $85 service call fee. I decided to watch a HDTV program last night --> SURPRISE, set won"t power up today. I could repeat everybody else"s stories about Sony reps, etc., but would rather ask this question: HOW CAN WE INITIATE A CLASS ACTION LAWSUIT AGAINST SONY?

Registered: Mar-06Posted on Thursday, March 23, 2006 - 18:11 GMTIf you aren"t terrified after reading our posts, find a repair shop & ask them how many Sony boards they"ve had to replace (e.g. B-boards, C-board or D-boards). "Authorized" or not, they"ll prob"ly tell you the truth ==> the boards fail a LOT and the replacement parts are often worse (i.e. they may be DOA or fail soon after swapped in). If you CAN, buy extended warranties on both sets NOW; its only a matter of time before the sets fail. * * * Note: this is my personal opinion. I am not affiliated with Sony or any other brand. I"m just another victim.

Registered: Jun-05Posted on Friday, March 24, 2006 - 14:00 GMTI don"t know. I think I"ll save the money. I"ve read the post and people slam plasma displays and say they won"t last but we have a Sony plasma in our lobby from June 1999 and it runs 9 hours a day or more, 5 days a week at least and it still looks very good and I still have plenty of brightness and contrast in reserve. It would be hard to believe we just got lucky on that one. I hope my LCD lasts a long time but I know there is something better out there now so maybe a couple years down the road, I"ll replace the Sony with something else.

Registered: Apr-06Posted on Friday, April 14, 2006 - 14:02 GMTWow, not too sure what to do now, I have already bought a Sony KFE42A10 LC projection TV. Should I consider refund it before the Future Shop ship me the TV next week ?? What is a good brand name for projection TV or should stick with Tube TV since I cannot afford Plamsa or real LCD TV. Thanks for any information

As an FYI, my technician told me during the first call that there is a "technical bulletin" regarding this problem on Sony"s Internal website. His guess is that it was a quality control problem where dust was getting on the LCD before it was sealed and over time (and hours of heat) caused a crack (which results in the roadmap image).

As for these new LCDs, I guess I would recommend purchasing the extended warranty either at the point of purchase or from Sony directly. Thanks to this forum, I will be buying the full 4 yrs additional from Sony before my standard 1yr is up.

Registered: May-06Posted on Wednesday, May 17, 2006 - 19:37 GMTMine is a 70 inch Sony LCD purchased in September 2004. In October 2005, the magenta road-map appeared on the left side of the screen. On some advice from this site I left the TV on for 4-5 days and the road-map disappeared. It was fine until the first of May 2006 when the magenta road map appeared, this time on the right side of the screen. After leaving the TV on for a week, the road-map disappeared again on May 16. I don"t know if I"ll turn it off again. I find it interesting that an apparent electronic defect cures itself. Why would that happen? Can it be so simple that some dust on the LCD lamp projects itself as a primary color? Sony should come clean on the issue. I will not buy any of their products again

I made the CC guys bring 3 (three) TVs until I found one without any imperfections in the LCD matrix or the screen (I"m a bit picky). Hopefully this one will not turn off...

The tech replaced the Optical Engine and Bulb. This was a rebuilt part to the tune of $1041.25. The replacement part is bad. The tech said it came out of a Smokers House set. I am now waiting for the 2nd. replacement to arrive.If this one is bad I will deal with Sears service for a replacement set.

Registered: Sep-06Posted on Tuesday, September 12, 2006 - 02:53 GMTI have model KP46WT510. This is my second go around with sony. This was a replacement for my original model KP43T75. Once again after year two the convergence has gone bad. It appears Sony"s Prjection TVs only last 2 years and they are done. Does any one know what convergence module fails? I would like to direct the tech guy so he does not lie about the problem.

Called Sony"s worthless support line and the rep had me turn off the TV, unplug it and then plug it back in again. That did not help and the delay occured again followed by a screen covered with multi colored vertical lines. Using the remote, I tried to get the menu to appear, but nothing but the multi colored vertical lines appears on the screen. the worthless sony rep told me I have a blown picture tube...that"s when I lost it and asked to talk to her supervisor as the LCD Projection TV does not have a picture tube. She came back 5 minutes later and said since my TV was out of warranty, I would have to have a service rep come to the house at my cost to evaluate the problem. Has anyone else ever experienced the multi colored vertical lines filling the screen with no ability to access the menu or any other function?

I have a Samsung 26" LCD HDTV in my den that has always had a better picture than the Sony, and after this experience I don"t believe I would ever buy another Sony product. Has any one had any experince with the Samsung line? The contrast is the same as the 26" I have in my den 5000:1, so the picture should be better than the Sony.

Thanks again. The service tech came to the house today, and when he called Sony, the tech department told him there is a service bulleten out on my TV"s condition, and it is the "B" board video processor. The total repair for the $300.00 "B" board and labor including todays visit would be $588.50. I called Sony and they agreed to pay 50% of the cost of the repair. So I"m only stuck with $269.25 to get my 22 month old Sony KDF50WE655 50" HD LCD TV fixed. Not happy that it broke after 22 months, but I can live with the cost.

Of course LCD goes bad and produce stuck pixel when time goes by but it usually not "massive" number. It almost like domino-effect. one goes bad and the other also affected and goes bad.

I"m not sure about blue corner part but since random dots appear center of the screen I think somehow LCD got heat damage. (which could be manufacture defect of optical block)

I have owned the KDF50WE655 50" HD LCD TV for around 2 years now and after reading this forum I feel like I am waiting for a time bomb to explode in my livingroom. I extended the warranty thru Sony for 3 years recently after reading the many problems on this page. So hopefully I am covered.
