Re: Dead digihome tv

There are 3 boards on the back. Power board, av main board and at the bottom left I think is the t con board. The wires heading to the bottom right is for the remote sensor and standby light. Plus 2 speakers. Are the voltages ok in previous post?

Re: Dead digihome tv

Re: Dead digihome tv

can you retest the voltages on cn4 connector test the outer row of pins 3,5,7,9,11 all boards connected tv switched on multi meter dc volts black probe tv chassis if you still have you old power supply maybe test both supplies.
Budm if you have a minute can you have a read through this thread do you think its a main board fault? thanks.

Re: Dead digihome tv

Ok i will re check both boards later after work.

Re: Dead digihome tv

Your old power supply should be ok, if both boards read the same voltages you could re sell one of them and get some money back towards the main board or just keep as a spare of course.

Re: Dead digihome tv

Sorry for late reply. I've tested with all boards and components connected but power and av board are off the chassis ( I can't test all pins with boards fitted)
Following pins have voltage only the rest are zero v
Pin 14 12v
Pin 12 12v
Pin 10 12v
Pin 13 12v
Pin 11 12v

Re: Dead digihome tv

I've uploaded the flash for this mainboard in the eeprom thread. It'll work in this model. Same panel except NO1. Won't matter though.
