1 YEAR AGO, THE FOCUS WENT ON MY TV, IT SEEMED TO GET BETTER WHEN IT WARMS UP, THEN ABOUT 1 MONTH AGO, THE PICTURE FLASHES ON AND OFF CONTINOUSLY, UNTIL YESTERDAY, THE PICTURE WENT BLACK.
THE INDICATOR BLINKS 5 TIMES INDICATING: CHECK (AKB)CIRCUIT VIDEO OUT; Q705,732,761 ON "C" BOARD. ALSO CHECK; Q218,219,220 ON THE "A" BOARD.
WHAT TESTS DO I PERFORM TO CHECK THESE COMPONENTS ?
WHERE IS THE (C) BOARD AND (A) BOARD LOCATED FROM ONE ANOTHER ?
IS IT COST EFFECTIVE TO REPAIR THE BOARD RATHER THAN REPLACING IT ?
CAN SOMEONE PLEASE HELP WITH SCHEMATICS AND/OR A REPAIR MANUAL?
I AM A COMPUTER REPAIR TECH SO I FEEL CONFIDENT IN DOING THE REPAIRS MYSELF - ALSO, I CANT AFFORD $1000. FOR THE SONY TECH !!
ALL HELP IS APPRECIATED!!!!!
If you can read a service schematic and have a program called Pando, Yes maybe I can share a copy of This model number with you.
LARRY, THANK YOU, I CAN READ A SCHEMATIC, AS FOR PANDO, I DONT HAVE IT BUT I'LL TRY TO AQUIRE IT FROM SOMEWERE, IF YOU COULD PLEASE E-MAIL ME A COPY OF THE SCHEMATIC OR SERVICE MANUAL, IT WOULD HELP ALOT, THANKS!!!

LARRY, JUST A COUPLE MORE QUESTIONS FOR YOU REGARDING MY TV
"3 SEPARATE PROBLEMS" PLEASE GIVE ME YOUR OPINION ON WERE TO START!!!
1) TV WAS PURCHASED IN FEB 2000, ABOUT 1 YEAR AGO THE FOCUS SEEMED TO GO OUT, PICTURE REAL BLURRY WITH GHOSTS , THE LED IN FRONT WAS BLINKING 5 TIMES INDICATING A (AKB) CIRCUIT FAULT, THE TV WAS NEVER REPAIRED AND LED STILL BLINKS 5 TIMES.
2) TO ADD TO MY PROBLEM , ABOUT 1 MONTH AGO, PICTURE STARTED TO FLASH ON AND OFF REPEATEDLY WHAT IS THE CAUSE OF THIS ? LED IS STILL BLINKING 5 TIMES FROM PREVIOUS AKB FAULT
3) TO TOP IT ALL OFF, ABOUT 1 WEEK AGO, THE PICTURE WENT OUT AND WON'T COME BACK ON , IF I TURN POWER OFF AND ON AGAIN PICTURE COMES ON FOR A SECOND OR TWO, COLOR SEEMS TO GET DARKER, THEN GOES BACK OFF COMPLETLY, LED STILL BLINKING 5 TIMES.
IF THERE ARE ANY MORE CODES I CANT RETRIEVE THEM BECAUSE NO PICTURE, CAN'T GO INTO SERVICE MODE TO SEE CODES.
THANK ALOT, I GOT SERVICE MANUAL YOU SENT, AND CAN READ SCEMATIC BUT WERE DO I START WITOUT SPENDING 1000.00 ON PARTS?
(A) BOARD COST 800.00 AND (C) BOARDS COST 93.00 A PIECE
Dude, I hope you still have the TV and didn't pay to get it fixed.
I have the same TV and had the same problem. Found the fix... all you need is a philips screw driver and five minutes...

AL-G that is not a fix! that is a crutch, Here is what is going on, The three crt's need to draw about the same amount of current, the set measures this by measuring the cathode return current coming from all three crt's if the micro sees that one of the tubes is drawing too much, or too little power, it will shut down. When you adjust the screen voltages, you are effectively modifying the cathode return current and bringing it into balance.
The real question is why did it get out of balance to begin with? - Because the crt is getting weak, that is why. I have fixed this before by adjusting the screen controls, but in a short time 6 mo to a year the problem will return, and you will not be able to re-adjust it any more. You are putting off the enviable of replacing the bad crt. I always let my customers know this. If you perform that adjustment, just realize you are postponing the inevitable.

Are they very hard to difficult to install
