kdsr50xbr1 lcd panel replacement manufacturer

Native Resolution:The KDS-R50XBR1 has three high-definition SXRD image panels, each with 1920 x 1080 pixels. Each panel has 2 million pixels, so there is no loss of detail. SXRD preserves every pixel of the source, and brings the full 1080 lines to the screen without interlacing, displaying the signal at 1080p. The resulting picture has incredible clarity and a smooth, filmlike quality.

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:

In the end, Sony agreed to pay half of the $1,400 repair to replace the panel. The service tech, a Sony gold standard place, says the set is defective.

Just ordered my replacement 65″ Panasonic plasma to replace my yellow KDS-R60XBR1. My friend’s XBR2 also went yellow a month or so before mine. I’m not interested in “deal”on a discount on a smaller set I never wanted and we knew nothing of the class action lawsuit. People tried to warn me that Sony is a company that treats its customers callously and doesn’t know how to do the right thing. Lesson learned. Never by Sony anything again. Tell a friend.

I just hung up with Sony on trying to get information about a green hue I have on my SXRD TV. The support tech actually lied to me 6 times before I was able to get ‘Dennis’ to admit the truth. Dennis stated that Sony has never had an ‘Optical block’ problem, that there had never been a class action suit on this issue, that they have never offered any kind of replacement, and the the internet had lied about all of this. I asked to be moved to a higher level and he stated that when he would transfer me that it would go to someone else of his level with the same information. How can you trust a company that lies to you right from the beginning?

I contacted sony about my KDS55A2000 with green tint. I purchased it 2006 and paid 2500.00.I am now offered a 55” priced on their web site 1100.00 for 575.00 + tax. I have a 20 yr. old magnavox 300.00 still working. Sony represented this TV to last a very long time with an occasional bulb replacement.They by there standards say this TV is worth 600.00 today.I GOT 5 YRS SERVICE or 500.00 per year.I was told if I didn”t agree to the deal!!!!! within 7 days I would lose this option.Yesturday morning I agreed with a very sinking feeling.I own 2 newer sony 46” TVs cameras play stations mp3s hell all of our electronics are sony.I am now of the belief that SONY has gone cheap with the manufacturing of there products.I took there deal but I won”t forget.I have a lot of friends and a bit of persuasion.Help from sony or I quit!!!!!!!!!

I just worked with Sony on my 55″ SXRD tv issue that included a yellow tint to the picture. The offer I got was for a 55KDL500 for $300 or a 46″ model for $25. I took the $300 55″. Shame though that the picture on the new LCD is not as clear as the SXRD when working well.

Have a KDS-R60XBR1 with optical block problem. Called Sony about two weeks ago. They provided an event # and asked that I provide a pic of the TV with the event number and the seriel number tag from the back of the tv. You must carefully remove it and tape it on the paper. I took a pic of the tv during a Ford commercial which has lots of white screen space which clearly shows the green halo. I’m now waiting for the 60EX700 LCD HDTV to be shipped ($325+tx). Thanks everyone for your posts.

I have owned a 60″ A2000 for approx. 3 1/2 years and have just recently had the optics replaced for the sixth time. I finally got fed up enough to contact Sony right before the fifth replacement and was told at the time that they would do nothing for me other than replace it again. After finding that the fifth optical block was bad right from the get go, I contacted them again. I expressed that aside from the incredible inconvenience and work time lost from having to constantly be home for the repairman, I was concerned that I would soon be out of any kind of warranty and be stuck with a tv that had never consistently worked right. They stated that they would get back to me within 72 hours. After a week had passed, I called again and was told that I would receive a call back in one business day. Four business days later, I called again. I was then told that they would contact me at an undetermined future time. When they finally did get back to me they wanted me to fax my original receipt to them so that they could then offer me some “great deals” on a new tv.
