Question about Mitsubishi WS-73713 73" Rear Projection Television
Turn on tv no piture
If the power light comes on (green) for a few seconds and goes off:
MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.
PRESS AND HOLD "device"(input) and "menu" buttons on front of tv for at least 5 seconds and then release both together.
Watch for power light to blink in a sequence:
1 blink-then 2 blinks-------no error
2 blink-then 1 blink-------X-ray protection
2 blink-then 2 blink-------SHORT PROTECTION*******
2 blink-then 3 blink---------deflection circuit problem
2 blink-then 4 blink---------vertical circuit problem
******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC's is blown---set will detect no voltage to convergence IC and shut down.
SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.
IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM
let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.
