sharp microwave lcd display repair factory

Innovative thinking led to the world"s first Microwave Drawer Oven, an appliance that has helped revolutionize kitchen design and microwave oven placement. Now Sharp introduces the next generation of this successful appliance- larger, sleeker and more accessible than ever. The new KB-6524P series fits in the same space as other Sharp 24-inch models, yet it"s larger 1.2 cubic feet interior is tall enough to hold a 20 oz. cup from your favorite take-out coffee store. Plus, there are two convenient...

I first tried when the glue gun was a little colder so as to be safe. I missed a couple of pins or solder strips whatever the individual connections are called on the first pass but was heartened that I fixed most of them in the first attempt. The tip of my hot glue gun is flat and I used the gun vertically up and down the strips a few times. I also gave the other end of the ribbon a thrice over where the ribbon connects to the lcd. I don’t know if that helped but I don’t have 2 microwaves to compare it to. Another important point is don’t just screw the screws back in but turn the screw driver as you are undoing the screw until you hear a click. Then start to do up the screw. This will make sure that you don’t start a new thread and cross thread it as you put it back in. Also the bare wires (red wire without a hood cover has a spring clip so it will not pull straight off. You need to look close to see what I am talking about and push back the spring clip with a fine screw driver like a jewellers screw driver. Thanks for the great photos!!! I could have put a strip of hot glue down but there seemed to be no need. If it fails again I will do as he suggests and I might even resolder the strips. Too much of a headache. Kind Regards Wayne

I have a Sharp R350E that is terribly loud…….the customer service person’s answer to my inquires was “I’ve never heard of a loud microwave”…..good for him! (I should just go away. They must pay him to just get rid of people.) He wasn’t helpful at all and inferred it just doesn’t happen – I must be imagining it. I took it to a local service person ($40.00) instead of incurring even higher costs of an in-home vservice call and the service man said “Wow, this is a loud microwave!” Turns out it’s a loud transformer and I get to pay $160.00 if I want to hear other people talk while in my kitchen with me. New microwave exact model is $288.00. ANy chance you know where I could get a new transformer…. the microwave works perfectly. Just two of us and 2 years old out of warranty etc. Thanks so much!

If you are in NZ then the law (Consumer Guarantees Act 1993) should be on your side with this one. I’d recommend taking it back to the retailer you purchased it from and demand that they repair it due to it not being of acceptable quality and not lasting a reasonable lifetime. The Act applies even outside of the warranty. I have successfully exercised my rights in the past and had faulty goods repaired/replaced outside of the warranty period at no cost to myself.

Unfortunately I’m not sure where to buy microwave oven transformers. TradeTech sell microwave oven parts but I don’t see any transformers on their site. I’d imagine they would all be pretty expensive though as they are quite bulky. What about eBay, or scrounging around for a similar, older model (like one with a dead display!) and seeing if the transformer fits?

The fix works well but the display is still a bit dim if a lot of characters are displayed. Was a bit worried how much heat the cable could take so have taken it pretty easy with the soldering iron. Was good to see the LCD work again as the rest of the appliance works really well. Hope the newer models have fixed the design fault.

We also tried with a soldering iron, the first time we got more display but on second attempt we accidently burnt through some of the ribbon:( I was shattered. We then attempted a repair with some metal melted with the iron but caused more holes and when the patch was finally done we turned on the microwave only to discover that the back light is working with absoltuely no display. I am so dissapointed. Our only hope now is to find on old one no one wants and swap the display. But then again if we do find a microwave thats the same we will just use that and throw this one away. Sooo shattered, it does work but be careful this dosent happen to you!!

Thank you very much for your great advise. My microwave didn’t have the back strip. I had a small hot glue gun that i had not used in years I am glad I didn’t throw it away. I ran the glue gun several times on the strip and it worked wonderful the first time. Thank you all for all the advise I saved about $150.

Hi, I would like to have a go at mending the LCD on my Sharp microwave and having read the advice above have just one question. In order to access the strip is it necessary to open up the back and do all the disconnections mentioned by the first person before you can remove the front panel ? I must admit I am a little apprehensive of fiddling round near capacitors etc. I may be reading it wrong but from Wayne’s description it seemed that you could access the strip just by removing the screw and sliding out the front panel.

Thank you from me too. My microwave LCD had been gradually fading for years, finally just going dark. The microwave works fine, so we just have been running it blind. I saw your blog entry and decided to try it. IT WORKS. My microwave did not have the glue as yours, but the same as other posters. The hot glue gun (minus the glue) fixed it just fine. And as a bonus, the same thing worked on the dead LCD on my AT&T phone (CL2909). It had been dead for years. Now it works. Wonderful, thanks!!!!!

Thanks! Our Sharp R-490C(S) microwave LCD screen died about 5 years ago. You know the story…other than the LCD it worked fine, you just had to guess what you were doing a bit.

Today a local retiler (Neol Leming had 25% off all microwaves, so we decided on a model to get and were walking out to the car…. Actually my wife was outside waiting when I had one more look at Google and found your amazing advice.

Used Wayne’s hot glue gun method on my Sharp R-653M. After second attempt works as good as new. Make sure you apply careful pressure to each terminal in turn but not too long. Brilliant tip, thanks a lot.

Wow. Thanks for this! Been living with missing segments for actually a few years. It was always usable, but kind of annoying every time I looked at it. A cheap microwave and tempting to just replace, but I hate that kind of waste. Tried Wayne’s hot glue gun fix and all is good.

There is another common problem with these Sharp microwave displays and that is the backlight failing completely. It is simple to fix: take a ultraviolet or white 3mm LED with pre-soldered resistor rated for 12VDC and with pre-soldered leads and solder it to the points on the circuit board that are meant to feed the failing LEDs. You can use a multimeter and follow the traces to locate where the +12VDC and ground points are.

Great news, guys! You can do this fix with a heat gun affixed with a small-diameter nozzle! Just aim the hot air at the back of the LCD ribbon, heat it up, and then use a plastic stick to press the tape down as it cools. I did this just now with a 1cm nozzle and got all my LCD segments back, all without any risking a melt-through using a hot glue gun or soldering iron…

My father-in-law loves his old Sharp microwave and is too old to easily learn a new one – otherwise I wouldn’t have even tried the opening up a microwave as detailed here. My first obstacle was just getting the cover off – two of the screws were odd star-with-center-peg things that I almost gave up on, but finally managed to get out with careful use of pliars. Then once I finally got inside and got the board got the out, the ribbon connector did not look like the photos – that is, no line of black glue, just an almost invisible very thin transparent glue strip. Figuring I had nothing to lose, I ran a glue gun up and down it a few times, put everything back together, and the display worked perfectly! If I can do it, anyone can.

I have a Sharp R-1514 that has this exact issue. I opened it up, scraped all the glue off and applied new conductive glue from RadioShack….nothing improved. I have the same dimmed, semi-working LCD screen as I did before. I don’t know if it’s even worth doing it again because I’m not confident anymore that this is my the solution to my issue

That said the warning on the back is there for a reason too – a microwave oven does contain high voltages when operating and the capacitor can still retain a powerful charge after the the unit is switched off. If you don’t feel comfortable working on the unit then I’d recommend seeking advice from someone more experienced to be safe.
