SOURCE: SONY GRAND WEGA KF-50WE610 can't turn on TV screen.

Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,
Dan

SOURCE: sony xbr 60 grand wega color problem.

It sounds like to me you have a bad Optical Block. It is a expensive repair and you may want to call Sony at 1800-222-SONY and see if the would assist you in repairs. Due to the age of it, they would probably only cover a partial amount of the repair.
Hope this helps,

SOURCE: Sony Grand Wega 60 inch LCD Projection TV goes dark.

most likely, buy you a lamp and install it yourself, the owners manual tells you how to do this.

Color splotches


I had same problem, or should I say I still have it, slowly getting worse, and I had replaced the Y board which would be logical based on description of what board controls, but it didn't help. I found out it is the plasma screen, and not worth replacing, so I put up with it until picture is all full of shadows, then will part it out. Last time I had issues with capacitors a few years ago, I spent $400. on several boards, including Y board trying to isolate problem, that is how I learned it didn't help the shadows creeping in after warming up. Live with it or buy a new TV is what I am doing.

My Insignia NS LCD 37 will power up but the screen is gray and there is an even lighter gray bar going up and down but no picture


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

Projection tv color


If I may - - the Grand Wega has a common color wheel problem and it may not be the fan at all... If while you are powered up listen carefully to the noise as you hit the power button - does the noise go away or is it still there? If rough noise stops and you can still here something in there running at a whisper then your problem is a bad color wheel not a fan... If it doesn't stop and it is the fan you'll most likely need to replace it..
