Yellow streaks on tv screen

tyr to factory reset device on advance settings
with out the memory card

The yellowing of Sony’s KDF-60WF655 rear projection is a problem with the SXRD optical engine. This turned out to be a big problem on many of the SXRD TV's. Sony actually had a class action lawsuit that covered the optical engine for 5 years. My unit was replaced in June of last year (2009) about 1 month before the coverage ended. My unit had a bad yellow streak on the right hand side. Sony no longer covers the cost of replacement, as the class action suit has now expired. Sorry for the bad news. Its not clear if a new optical engine will suffer the same fate after a few years. Sony’s rear projection TV's are amazing and the picture rivals many of today’s LCD's and Plasma's. Any authorized Sony Tv repair shop will no exactly your problem and will be able to give you a fixed price to repair.
Hope this helps

A yellow streak down the middle of an LCD Direct view TV (Not projection) is almost 100% the LCD panel. NO, just buy a new set.

Your yellow problem sounds like a bad yellow developer housing. Take the drum out and look at the developer housing, You will need a flash light to do so. See if the roller is solid yellow. Even if it is there may not be any developer left in the housing.
The Cyan sounds like the drum since it gets worse as it prints.
That can also be caused by the transfer belt cleaner. But that normally is the opposite. It has a rainbow sort of streak and it gets better as the machine runs.

Sounds like a pixel row. Not a fix available.

I took the scanner apart. Then using a dampened eyeglass cleaning cloth, I gently cleaned the 3 internal mirrors.
No more yellow streak! :)

sounds like you need to do convergence.

Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

It could be something on the crt embedded that looks like the screen.

the tv color circuit is off frequency change the color ic take a look on the crystal that gives the 4.8.mhz burst could be that it needs to be replace dont rule out the video IF change the two ICs you mention.good luck.from the look of your tv screen that is my conclusion.good luck.email me at [email protected]
