Question about Toshiba 53H71 53 in. Rear Projection Television

1 Answer

My 53H71 Toshiba TV all of a sudden started blinking

The TV is about 6-7 years old and has performed perfectly the entire time. All of a sudden it started blinking , like the picture would get kind of wavy and flash big to small and every size in between in seconds. This will continue for a while and then all of a sudden be perfect.
I took the back and front bottoms of and blew it out and no help. I also unpluged if for an hour and I also turned the breaker for the plug off for a half hour and it did not help.
When it starts going goofy the sound kind of goes goofy too.
I know it is not the signal because it does the same thing when I put a DVD on to play.
Can anyone help identify the problem/recommend a fix?
Thanks
Rick

There is a problem in the control board and the unit is doing self diagnostics.  Since the problem occurs again the board is unable to fix itself and needs service.

Look carefully at metal jumpers feeding b+ to convergence IC's.

Both will need re-soldering or you will keep having problems. 

Let me know how it goes.T.
