Hello , my name is Jack Perhaps I can help you with this problem but first i would have a few questions;
While the red standby light at the front would be normal , does it turn off or flash when you try to turn the tv on ?
How long since you bought this tv now ?
no the light doesn't alter in any way when I try to turn the TV on, just stays on.
And he TV was bought about 2 years ago
Unplugged the power cord. Do not have the Mac book connected nor the HDMI cable at present.
O.k then it does sound like you did try to perform a processor reset .
In that case then there is no other form of reset that could be tried with this model.
Sorry to say but in this case and it looks like an internal failure/problem.
Was there a lightning storm or power outage since last night ?
No I don't believe so as I had few other things plugged into the same power strip and they are fine today. Also am in LA and there have been no storms here recently
Thanks , you answered my next question, which was ; is there other equipment not working .
O.k then at this point without being there with tools and meters , it would be difficult to be adamant but it does look like a main board problem at first as the tv does not respond to the power command and that red light doesn`t blink or change at the front.
This usually indicates that the control processor does not responds and that processor is located on the main board.
Second in the list of possible cause would the power board circuit although I would be surprised in this case.
There is a few ways to find out but the back cover would have to come off and a voltmeter would be required in this case.
So my next question would be ;
Did you wish to look into repairing this yourself or just have an idea of what is involved and an idea of the cost of repair ?
Not too technical mate so an idea of what is involved and the possible cost,would be fine. I am subletting this place so need to tell the actual home owner about it. Thanks
As I said then in this case you are most likely looking at a main board fault and that board part # XXXXX cost around $125 to buy .
In which case you would be looking at a repair of approx. 250 to $300 to have repaired at home.
In the best scenario you would be looking at the power board which would cost around $250 to have done at home.
