This is a sign that the video board in the TV is actually failing... starting to go bad basically. Do you think you want to try and do the repair yourself, it is not easy unless you have done TV repairs of this nature in the past.

Please let me know, I will be glad to help you figure out what part exactly and where to get it from..

Thanks, just reply to my answer here and I can help.

I HAVE A SONY KP-53V90 53 INCH REAR PROJECTION TV AND THE COLORES ARE NOT MERGING TOGETHER PROPERLY I THINK THIS IS CALLED A GHOST IMAGE HOW CAN I FIX THIS


You have a convergence issue, will have to check convergence IC,S or just replace them there are usually two of them mounted on heat sinks they are usually STK'S with a number after. Also must check fuseable resistors supplying +15 and - 15 volt s to the chips. After replacement some convergence alignment may be needed. Good Luck.

I have a Sony KP-53V90 53 with no display and red light flashing


This is a good one. Your TV "looks" at the feedback coming from each picture tube in your TV. When it doesn't see what it expects, it kicks out a 5 flash. Most commonly, the correct signals never got to the picture tube(s) and that's why the feedback was abnormal. Which brings us to the most common solution: C boards, they attach directly to the bottom of the picture tubes. Figuring out which one has a problem... that's another matter. Due to the age of the TV, parts costs are rising. Each C board (3 in the TV) runs about $100 so guess work can be expensive. I hope this was helpful.

I have A sony kp=53v90 tmier stand by light falshes twice


Well I believe you are on the right thought pattern.
I beleive this is an older CRT rear screen projection TV.
Could just possibly be a Power supply issue or a bad HOT 'High Output Transistor.' It could also be a flyback issue.
Will need to be taken in to a trusted service shop to have it looked at. May be a time to look for a new TV. Sorry!
