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 12vLeave a comment:

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?...Leave a comment:

These are the pins with voltage
Pin 7 2 or 3 v
Pin11 11or 12v
Pin 12 11 or 12v
Pin 13 11 or 12v
Pin 14 11 or 12vLeave a comment:

Re: Dead digihome tv
Ok The confusing part is matching the diagram up ro the connector and the board has no marks to say which pin is which. I can only assume that cn3 diagram matches the 20 pin holes on the board cn3. Am I right reading this diagram refers to looking at the back of the board? Pin 20 top left pin and bottom left pin 2.Leave a comment:

Re: Dead digihome tv
I have only gone as far as inspecting the board for bad caps, loose components or damage. The board is receiving power as I can hear a dim buzz from the transformer.
As far as testing goes what should I be looking out for?Leave a comment:

Dead digihome tv
Hi all. I have a problem with a digihome TV and wantvto fix it model:49278fhddled. Under the panel there is also another model number VES49undl-2D-N02. My problem is the set seems dead with no picture,sound or standby light.
The power supply board has been replaced vestel 17ips71 but still same issues as above.
The power cord cable and fuse are ok and there is power getting to the board.
Im just learning electronics so be easy on me lol
If the power board is ok could the main av board be at fault pn 17mb82s 23289383 and cause the no power symptom?
Thanks... -
