Hi There,

your money is safe there if somthing wrong you can open a dispute and discuse with the seller the isue

but i think i will buy a new one not a used .it is beter for the long way using the TV

Hi shopyd,

I assume you need to start this tv by connecting PS-ON to the Standby Volts. Is it not possible then that it's

the Main board that's faulty.....not supplying PS-ON to activate the power supply. Have you stuck a meter

on the PS-ON pin to see it remains high after power-on?               Bruce

shopyd:
thanks bruce

i did this by jumpering the standby pin and the pson on the power suply and jumpered the standby pin and the inverter on .i disconected the main board and do it only on the power board .but when i conect the power to the board the ccfl light for few seconds and shut down.so i assume the problem is the inverter.

what you think

david

downunder:

OK. I think I understand now. It definitely appears to be the I/P board that's faulty. Unfortunately

I have never diagnosed one of these to component level, so I can't advise which component may

be causing it.            Bruce
