    I believe I have the same problem. . .a large oval blue stain against a dark background and a yellow stain against a white background. A repairman diagnosed it as a failed optical engine, a $1,200+ repair.

    got the same sorta problem with the KDF-E50A10, mine is a line of blocks in the middle of the screen. the repair guy on the phone told me it's the optical block without even looking at it. Sony wouldn't cover the repair. i told them i would even pay for the labor if they paid for the part which they said no. But, they are giving me a credit towards a new sony. i had to send them my original receipt, which i didn't have but the store i got it from was able to look it up and get it to me, even after 2+ years after i bought it. Sony is offering me the KDL-46V4100 for around $495 and the 52" model for around $900. i really like this TV too. oh well. in the end i will have to take off the serial # sticker from my old TV and mail it to them so nobody can call in about the same TV. I'm going to try to sell it cheap and try to only have to pay a couple hundred bucks for a new TV. I'd rather go with a Samsung, but i can't pass up the credit.

    I also have a 2005 KDF-E42A10 with a blue haze at the bottom of the screen that started right before Christmas. It seems to be growing.

    I'm calling Sony about it to add my name to a growing list.

    I have the same problem, blue haze all over the picture, I bought mine from Circuit City about 2 years ago and I don't know who to contact or handle this situation.

    I bought my Dad this TV for his 80th birthday in March, 2006. Now 2 years and 11 months later it has developed the yellow haze on both the left and right sides of the picture. Of course the warranty was only for 2 years. I have been a faithful Sony customer for over 20 years and have never minded paying more because I thought the quality was excellent and never imagined anything like this would happen within such a short time. Then I find out it's a problem across the board with these TV's, Sony is aware, and that the warranty on certain models (not this one!) has been extended. I am writing a letter to the Executive Review Committee and want them to include this model on their extended warranty. I am very disappointed in Sony.

    KDF E42A10 - Our our tv was under 3 years old when we started experiencing the blue blob. Called customer sevice. Had an authorized repair center out and they diagnosed it was the optical block. The repair fees are $350.00 for labor and $650.00 for the optical block. Our cost for the diagnosis $105.00. Sony refuses to pay any of the repair fees or diagnostic fee. They only offered a discount on a new tv. If they think we are going to give them another cent they are crazy. Will never buy or recommend another Sony tv to anyone.

    I have the same blue haze issue with the KDF-E42A10, that I just noticed January 09.  I also called Sony support and the would not cover labor or the part cost.  The customer support reps were very nice, but said their hands were tied because this model wasn't on the extended coverage list and suggested to write the Executive Review Committee.


    Someone just posted on the Agoraquest forms about a class action lawsuit that's been started to get the KDF-E50A10 and KDF-E42A10 covered.  I'm not a premium member of that forum so I can't see the lawyer's email address posted there.  I'm not a big fan of class action lawsuits, so I'm not sure if I'm going to join or just take my loss, buy a new TV and never buy a Sony product again.  I think that the other models with the same issue were covered only because of a class action lawsuit, so maybe that's the thing that will cause Sony to change their minds.

    I HAVE THE SAME MODEL KDFE42A10. I KNOW IT IS THE OPTICAL BLOCK BECUASE THIS IS THE 2ND REAR PROJECTION TV FROM SONY I HAVE HAD THIS PROBLEM WITH. THE FIRST ONE WAS UNDER WARRANTY, BUT THE RETAILER REPLACED IT WITH THIS NEWER MODEL.

    NOW THE SAME THIN IS HAPPENING AGAIN AS OF THIS MONTH FEB, 09 & SONY WON'T DO ANYTHING. TECH SUPPORT WAS USELESS. THEY HAVE ME RESETTING MY TV, UNPLUGING THE CABLE BOX, ETC.

    IF I DID NOT HAVE THIS PROBLEM BEFORE ON ANOTHER SET, I WOULD NOT KNOW IT IS THE OPTICAL BLOCK, BUT I KNOW IT IS. I WILL PURSUE HIGHER LEVELS AT SONY TO SEE WHAT HAPPENS; BUT IN THE MEANTIME, THEY ARE OFF MY LIST FOR ALL FUTURE PURCHASES WHETHER IT IS PC'S, CAMCORDERS, BLU-RAY, ETC.

    I have same kind of problem

  • yellowblob Apr 20, 2009

    Same problem.I have a yellow blob growing in the bottom middle of my 2005 Sony kdf-E42A10. I noticed it starting in December of 2008 and now it is a complete distraction while I watch the television in April of 2009. Called Sony and explained to them that I thought the optical block might be a problem. Sony said there has been no recall on this model product for the optical block. I am thinking about joining the class action suit. I know there was a similar class action suit filed on other Sony projection television models.

    I just got off the phone with Sony customer service and I'm exhausted. I spent 20 minutes arguing with Chuck, the service rep. By the way, someone needs to take his pulse, he might be a robot. When I fall asleep tonight, I'm going to hear Chuck's monotone voice repeating the same phrases over and over. "Ma'am, that model is not on the list of televisions with extended coverage.." When I explained to Chuck that my model, the E42A10 has the same problem, the optical block, causing a blue stain in the center of the tv screen, he kept saying "That model is not on the list of models with the optical block.." in that same flat voice. I don't know, maybe he is one of the ASIMO prototypes that they have working the phones. I also explained to Chuck that there were several customers on the internet in different forums complaining of the same issues, so obviously this model has the optical block problem, too. He could not respond clearly to this logic. When I asked to speak to someone else, he put me on hold, and never came back. Not good. I bought this tv for my 68 year old mother in 2005. So, what's next? Class action suit? I read that someone had managed to get a credit for a new model. I don't want that, I want a Samsung.

I have the KDF-E42A10 and my co-worker has the 50". Similar problem started in early September and it is definitely the optical block, which is due to a faulty manufacturing design flaw. Spoke with half a dozen people at Sony, including their National Customer Relations Customer Information Services Center and all have the same response that "they understand it is an issue but they are unable to accommodate since our models are not part of the extended coverage list". Basically they do not have enough complaints to justify adding our models. So anyone with a 2005 model I suggest you write a letter to these two addresses and voice your concerns, issues, and complaints. They do review these on a quarterly basis and if they do notice an increase they may consider encompassing our models. Unfortunately in the in meantime you may have to pay for the repairs out of pocket but hopefully when they finally include us we will seek reimbursement.

I have the same problem with my KDFE42A10. It is a known problem with the optical block engine. Sony has agreed to pay for the repair on 8 or 10 other models with the identical model, but NOT this one. I have been arguing with them for 4 months to get this model added to the list. Very frustrating. They KNOW it is a manufacturing defect!

I suggest you contact Sony and demand they add this TV to the list for free repairs.

I have a tube tv. the picture as lines and is blur that goes in and out.


If the lines are colored DIAGONAL lines, they are referred to as "retrace lines," which indicates either that the picture tube bias is set too high, or the brightness level is set too high.. If the blur occurs when the image is particularly bright or a particular color is bright, it is referred to as "blooming." This is caused by either a weak high voltage circuit or because the picture tube bias is set too high.

Is the picture set very bright? Try reducing the brightness control to a level where the retrace lines disappear, and reducing the contrast control below the level where the blooming occurs.

If the television is more than ten years old or has many hours of use, the picture tube may simply be deteriorating normally. By nature, they have a limited life span. Before you decide to throw the set out, if you are technically-inclined, try adjusting the bias and screen drive controls for the television as recommended by the set manufacturer (you didn't specify what make or model the set is), and you may get a few months or years of additional life out of the set.

Sony Trinitron picture turning green hues


Nowadays CRT's do not have good quality shadow masks anymore. After heating up a little they can give a so called "blooming" effect giving a blue an yellow leaf effect large over the screen. Reason nonparallelity in deformation of the shadow mask.
