toshiba 43 inch rear projection tv

petermark:
i hve a 43vj33q toshiba thats stuck in standby . it makes no attempt to start up at all with either remote or front buttons  . i have replaced the three convergence ics which made no difference . i can get the power supply to operate by shorting pin 3 + 4 on the microprocessor and all the voltages seem ok according to the service manual but there is no pic or sound . wondering now do i have a microprocessor problem or maybe a corrupted eeprom . anybody have any further ideas

regards

peter

Hi P/M,

There's talk of PS fuses in back threads - nothing else - Chris.

JAYROD:
Peter, on most toshiba rear projector tv`s the most common cause of this fault is a faulty text module.The tv will work if you remove it. Also the 100 hz modules are prone to faliure.

HI
This should be the protection of the machine moves, the most likely site is the convergence circuit failure

petermark:
i have looked for the text module but cant seem to find it where is it located on this set . i have also replaced the convergence chips but they made no difference

regards

peter
