The light does not come on.
It was made in December 2006
Do you have 5v dc at the power switch?
is there 5 volts at the LED?
0 volts at the LED.
If I unplug the tv and plug back in, the LED will blink green for half a second when I hold in the power switch. During this time there is a voltage jump at the LED but it is too fast for my voltmeter to read well.
Ok if you disconnect that control board by unplugging the wire going to it and then try to control the tv with the remote, will it come on then?
I disconnected the board and tried the remote power button. There was a small noise from the TV like when pressing the TV power button after plugging in the TV the first time. I wanted to see if the LED would light when using the remote power button so I plugged the control board back in. This time the remote was successful in turning the TV on!!
Both the TV power button and the remote power buttons seem to be working now. Any idea what changed or how I can prevent getting in this situation again?
I think that control board is failing, I normally recommend leaving them unplugged and just using the remote, as this normally bypasses the problem and you normally have no more issues that way. Only problem is the buttons on the tv will not work and the green light will not work.
