My sony rear projection tv flickers green then shuts down ,any help

Sounds like the Green CRT drive board is needing replacement. The Green CRT could also be bad but usually the set will shut down if its the CRT, so I would try the Green CRT drive you can get one from www.tvrepairworld.com

power light if it shuts down should blink a error code--count the blinks and a pause?

Sounds more like a color wheel, if the color wheel is not working properly the on board computer will shut her down. And will get weird colors or flickering colors.
Sometimes will also make noise.

absolutely, and if he spilled any of the fluid on the parts below the tube your looking at bigger headaches down the road, the coolant fluid is very caustic, stop running your tv and get a tech to check out your set right away, video-tek

you need a new Blue CRT you can get them at the following link.

Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.

· Which models are affected with the "flicker" problem?
A1: There are 12 models in total: KDP57XBR2, KDP65XBR2, KP46WT500, KP51HW40, KP51WS500, KP57HW40, KP57WS500, KP57WV600, KP57WV700, KP65WS500, KP65WV600 and KP65WV700.

could be three different things.

 

1. could be the crt itself as a tube with dfective phosphure wil do this

 

2. could be the vertical ic on the crt board

 

3. could be the focus pac.  located in front of tv with 6 adjustment knobs on it.

rodman, i just started having the exact same thing on my Sony (same model). it's about 5 years old. did you ever find a solution?
