Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

1 Answer

I have a Sony KDF-50WE655. It is 5.5yrs old. There are blue pixels in the middle and blue blurs in the corners and its getting worse. It was registered and I have received no recall notice. I had the extra 3yr warranty which has expired. Realistically, what can I do?

Sony has extended the warranty on many of those units for the light engine. And that is what is wrong with your set. You need to look around for an authorized Sony service center in your area and call them with the model and serial number. They will tell if yours is covered. Better hope so, cuz that is a very expensive repair out of warranty.

Blue-ish hues in left corner and middle of tv. getting worse sony kdf-55wf655


The Optical Block assembly must be replaced to fix this. This assembly runs around 800.00.
It has been a common problem and Sony had a factory recall on the Optical blocks but I believe that has expired over a year ago. To double check on that you can call them at 1800-222-sony.
I hope this helps,

3LCD Projection TV 2.5 years old displaying blue hue/blobs


I would first try a new lamp. If the reflector portion of the lamp has any defects, it could show up this way as the light would not be uniform. The next possibility is a defective light engine. The engine portion if not field repairable and would need to be replaced. Try the lamp first and let us know what happens.

Blue streak at bottem of screen


Hello,

You have the classic "blue blobs," In most of Sony's rear projection LCD's, the Optical block is bad. Manufacturer's defect. The blue panel inside of the optical block starts de-laminating (due to heat from the lamp). This is a very common problem. I have changed about 70-80 optical blocks myself over the course of about 4 years.

There is no other fix but to replace the optical block. Unfortunately, it will get worse, and will probably develop "stars," or stuck pixels, as well. You can call Sony and try to get some assistance, but the extended warranty on these sets has recently expired.

Hope this helps you in some way...

On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck

Kf-42610 blue hue and blue dots on screen


Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )
