Hi my name isXXXXX will be right with you. I may have a few questions to be able to provide you with a more accurate answer to your question.
what happens when you try to power it on ? is the LED flashing ?
no lights or clicks
i also don't have remote as i got this at a yard sale
Ok thank you for that information, why did you change the power supply ?
i went to a tv repair place and they diagnosed it
but wanted 280.00 for my 38 dollar part
Ok, when press the power button does the LED on the front at least flicker ?
let me turn out the lights and look
no do you think its the little panel with the power on button on it thats is bad?
I doubt it, here but here's what you can try just to eliminate that, the power switch is just a momentary switch, you could try just using a wire and shorting the switch for a second to see the unit powers up, if it does noit then as you there are only 4 boards in this unit the power you have changed, the tcon or inverter are not going to create this condition, this leaves the main board.
I tried a paper clip on that wire already to no avail
so replace the main board?
anyway to read if power is getting to main board?
Why would such a new tv fail? Power surge?
yes you can just check the power supply connectors from the power supply to the main board, there should be a 5 volt stnby voltage even when the unit is off and pluged in,
the voltages will be marked at the connectors
I will check. Thanks. I have a service manual for this tv from online source also. that my help
See you. Collect the pay
there has be a 5 volt stand by voltage to run the main board to except commands from the button assembly and the remote
gotcha. will check for a 5v reading on the connector to see if the power supply is getting to main
you can always come back to this post with foloow up questions if you need to.
if the 5 volts is there then the main is most likely the problem
