Question about Sony KDF-E50A10 50 in. LCD HDTV

2 Answers

Optical block i have a sony kdf-60xbr950 in which the optical block is going bad. Sony is going to pay for the light but they want me to pay for installation. There is a door in front of the tv with two screws to pull out the lamp i was wandering is this how you change the optical block or do you have to go to the rear to remove the part. I have a Sony KDFE50A10 with a bad optical block. A small red band across top of set has turned into a 6 inch wide band with a small blue band below it. I was told the repair would cost $1145. This set purchased in Sept 05. Problem began in Dec of 07.Not that many hours on it. Sony has told me that they will not help me on repair as set is out of warranty. Needless to say, will never buy a Sony again.

    We have a Sony KDF-E42A10 42" t.v. purchased in Aug. 2005 for almost $2000. It began to have a broad, yellowish screen tinge on the right and left sides of the picture. Additionally we noticed when we turned the set off, it had a faint "blue blob" illumination in the center of the screen for a few seconds. We took it to the Sony repair shop yesterday and was told the optical block was bad and it would cost nearly $700 to repair. (This charge reflects a repair discount since we purchased our set there!) A call to Sony produced nothing but profuse apologies that they couldn't help because it was out of warranty. We spoke to 3 different people, each being progressively "up the ladder". They ALL told us they have no record of any optical block issues with our particular model. An internet search has brought up countless complaints about optical block issues with our model, plus the other model which is listed our operating manual (KAF-E50A10). I'm now in the process of writing to the "Executive Review Committee" which we were told is our last option to try to get Sony to help us out with the cost to repair this DEFECTIVE part. We did not expect to buy a $2000 t.v. which lasted only 2 1/2 years! Like many, we are faced with having to plow a substantial amount of money into repair (good money after bad?) or have a very expensive paperweight. Stay tuned....

    I have the same problem with the optical block. My screen is green. We first noticed this in January 2008. The TV was purchased in November 2006. I received the same reaction from Sony. OUT OF WARRANTY. The authorized Sony repair guy told me the color block had to be defective from the factory. But Sony said "OUT OF WARRANTY" The cost to replace it was $1250.00. The bottom line is that I will never buy a Sony product or endorse their products again.

    Just to update since my last post. I did write to Sony's Executive
    review committee and received a prompt telephone response. They are
    agreeing to pay all but $240 of the $700 repair bill, although the set
    is out of warranty. We've decided to proceed with the repair and use it for a spare bedroom set as we've since purchased a new main TV -- this time an LCD. I have to say it was worth the effort to write to Sony and, while we would have liked for them to spring for the entire repair bill, we are satisfied with what they've offered to pay.

    The TV repairman just left our house with an estimate for a $1,300 bill to fix the optical block on our Sony TV. The repairman suggested that I look and see if this is a common problem with this brand/model of Sony. We contacted Sony and they told us that it is not covered under any type of warranty. What are my options? Thanks.

    Repairman said I have a bad optical block on my kdf-e50a10 with only 2 years of ownership. Sony told me there was a difference between the optical block problem in my model and the ones they would fix out of warranty. I think that is bull. They should just admit the problem with the block in all models and do what is right. That would be the only way to keep the Sony quality in my opinion. I now own a $2400 dust collector.

    Having same problem. In addition, I have 8 dashed horizonal lines running the middle of the screen and another 12 at the bottom. When looking at the horizonal lines from the top to the bottom they are in a diagonal row. Upon closer examination they appear to be pixals.

    I am experiencing simular problems with my KDFE50a10. Besides the bands at the top of my screen I also have 8 dashed horizonal lines across the middle and 12 dashed horizonal lines at the bottom. When looking at the lines from top to bottom they are in a diagonal format. Upon closer examination the bands and lines are made up of pixals. The screen looks like what's depicted below. Blocks on top with lines below it.

    The horizonal spacing between the rows is much closer and you can see through the blocks and lines in order to see the picture -- it's like a screen door. The TV was built in Sep 2005 and bought in Dec 2005. That's 2 and a half years. Like you, I expected better quality out of Sony: that's why I paid a premium for the TV. Repairman comes tomorrow so I don't know the actual cost, but it will not be cheap.

    I have also been told I need to replace the optical block. I have been getting green hues on the picture and have tried messing with all the settings. I have been quoted $1200-1400 just for the part. This tv is only 2 1/2 years old. What are my options? Sony customer relations said they will not help.

    I have contacted Sony regarding my Television model# KDF-E50a10. Their has been a growing issue online regarding the optical blocks on these models. I called
    Sony and they refused to cover my TV as it was out of warranty. I know it is not a coincidence that many other Wega models had this problem, and my Grand
    Wega is having the same problem. They say my model was not listed in the class action lawsuit so they can not help me. I will spend alot of time rallying
    other people with the same problem and forming a class action lawsuit. I spent $2500.00 for this TV and that is worth alot of time on my part. I found this
    lawyer and he is accepting cases for similiar models.

Sounds like a bad Optic Block....there is a class action suit against Sony for this. See if you join the suit or just call Sony and demand that they send you a replacement OB....labor would have to be on you. Good luck.

I have a sony kdfe50a10 and the picture in the middle is perfect but there is all around it a yellow color. I replaced the bulb around a year ago.

Hi my name is Roety,
I can help you with your issue,
Your Sony LCD projector TV has a bad Light Engine also known as the Optic Block.
Blue blurr, yellowing, green picture and white dots all indicate a bad optic block.
The whole Optic Block needs to be replaced , the possible good news is Sony may be covering it under warranty.
Some models have a three year warranty on the Optic Block, some expire at fixed dates, regardless of when purchased.
Click on this link here to see if your model is one with the three year warranty.
A repairman would charge over $750 to repair it out of warranty, call a sony authorized repairman or try to find one using this link Click here
I hope this is good news and has helped you find a solution
If you need more assistance,please tell me your

I have a KDF-55E2000 Sony Grand VVEGA Color Discoloration

Bad news: The issue can only be solved by replacing the optical block for the TV. This was a defect in the design of this TV. Replacing this part is very expensive (over $1000) and time consuming (need to take whole TV apart).

Good news: Sony extended the warranty for the optical block for this model. They are covering the cost of parts and labor for this TV. Contact Sony to have them refer you to a authorized service center near you.

Bright blue patch in center of screen.

The optical block is going bad. Contact Sony support and have your model and serial numbers handy. Sony sometimes warranties these even after the 1yr factory warranty.

Not a problem - just clarification

They are the same part. Sony reffers to it as the optical block, while other manufacturers call it the light engine.
