Did a Reeceyburger led repair on this a couple of years ago and it quit my daughter a year ago so I assumed it was another led so it has just been sitting. Got it of the shelf yesterday and plugged it in and back lights came on. Started checking things over and saw an lvds ribbon cable that looked a little off so I reset it and got picture and sound on air antenna.
After about an hour the sound quit so powered it down and back on and got sound again. a while later no sound and no picture, but had back lights, and was getting the no signal message.
Remote, or tv buttons were not responding completely. Could get it to turn on ok but no signal. If I hit menu, the no signal message would disappear but no menu. Also, when you push the power button to shut down, it takes awhile to finally shut down.
Checked power supply voltages and appear to be producing what is needed. Only thing I am not sure of is what the led volts should be. Getting with
plug connected:
led1:21v
vout1: 107v
led2: 21.5v
vout2: 109.9
Unplugged:
led1: .0850v
vout1: 128v
led2: .001v
vout2: 128v
Any thoughts or ideas? Main board took a dump? Thanks
