    SONY KF WE 50S1 PROBLEM WITH BLUE DOTS AND A GREEN TWINGE ON BOTTOM RIGHT HAND CORNER WORKING IT'S WAY TOWARDS THE CENTER OF THE SCREEN. THE ACTUAL PICTURE IS GOOD. IS THIS THE OPTICAL BLOCK ON IT'S LAST LEGS. NOT A DEGAUSING PROBLEM.

    Thanks for the help. Many hours of time saved by this advise. I feel sorry for so many people who purchased this sony system paying good money and for a 3 year tv. It was good to see Sony did help some by being persistant with their problem. I would have hated to be the first person ringing Sony about this problem just out of warranty. Thanks again.

This problem is caused by malfunction of the power supply unit.

Due to loose solderings of some SMD components on the power supply board, one of the supply lines could not provide enough current if the screen is bright.

Please be aware that at longer term there will be a big bang from the set and there will only be sound, or the set doesn't work at all. In that case, two of the FET transistors will be shortened.



The new power supply boards do have an improved design to avoid problems in the future.

After removing the back cover and the internal shielding plate, replacement could easily be done by removing only eight screws.

    Have you tried clicking the Photo button on the post editor's task-bar and following the instructions? Be sure to read all requirements and instructions. You are probably right to conclude that the problem is with the optical engine. However, due to the cost of a replacement,



    I suspect that the problem is with the optical engine. Its definitely not the roadmap problem or dust. I'm wondering if the optical engine simply isn't seated properly. What happens if you push or pull on the top of the set? Does the area affected change?



    The one gent was real close with his suggestion. Pull on the top of the cabinet. If the spot moves in relation to the edges of the screen, then it's in the engine. If it remains stationary, its the mirror. Those mirrors are notoriously difficult to clean.

    mostly it would be bad optical block.



    feel free for further assistance.



    thanks.

The liquid look is the best clue for indicating a bad block

Yes, you are experiencing an 'Optical Block' failure. Google 'Sony Blue Haze' and you will find a wealth of information relating to this particular occurrence. You could either replace it or get a new tv. If you need further help or have more questions, please let me know

Is this a European model, as I am in the states and don't recognize the number. It sounds like what I see here as being a bad optical block with the following conditions:
Is it a LCD or SXRD projector?
Does the problme show up on all inputs and is it visble in the OSD and menu?
If so, it is likely a bad optical block. Depending on the warranty and any extensions Sony has given in your area (in the US, Sony has extended the warranty on several optical blocks) you may have complete coverage, the block may be under warranty and you may have to pay labor, or you may have no coverage at which point you're looking at a pretyy hefty repair bill, think $800 - $1500 for the block alone. Hope this answers your question.

    If this is a LCD projector, degaussing will have no effect whatsoever.

    Yes you are likely looking at a bad optical block. You did not say that this was an LCD projector, but I am assuming so. Plesse disregard all of the other fixes offered; if this is an LCD set, then YES you have a bad optical block. Sorry!

The optical block is most likely causing the problem. It will continue to get worse. Sony may help with the repair since they have had a lot of problems over the years with their optical blocks across many models. On the older sets they usually only help with the parts cost. The average repair cost for a optical block replacement is $1200.00 to $1500.00. So if they help with the parts cost it really brings the cost down. Their customer service number is 1800-222-SONY.
I hope this helps,

SONY KF-WE50 Preojection TV


You most likely have a bad optical block. The blue dots are a pretty good indication of this. Sony has extended the warranty of some of their models to include an extension on the optical block replacement. I don't recognize your model number (Not a US model?) so you will have to check with Sony in your country to see if your set is covered. Please be sure to rate this solution. Thanks!

KF-42WE610 blue dots and blue vertical haize


Go to the Sony Web support site. If your TV is one of the models listed with the blue dot problem (there are pictures of what the screen looks like with this problem)on the site, Sony is now saying that they will cover the cost of the part and the repair. We did what I'm suggesting and are having our part put in today. Sony decided this was their responsibility for some models of their LCD big screen HD TVs in June of this year. We were contemplating an estimated repair bill of over $1000 until we found out they were taking responsibility for this problem. Good luck, I'm not a truly techy person, but hope I have pointed you in the right direction. We have been living with blue people, etc. for about a year now, feeling angry about spending so much for a TV and it going bad so quickly. Hope this spares you that. You have only so much time to take advantage of this repair offer...
