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
