The T.V. turns on and displays what input your on then the screen goes blank. If anyone has a service manual or schematic for this it would be great.

Re: Sharp LC-32HT2U Turns On Then Turns Off
OK, so the last picture posted is the top of the powerr supply board, and the first two pictures of the earlier post are for the Inverter board. Any top side of of the whole inverter board?
When the screen blanks out can you see the backlights still on? If the backlights are still on but no pictures, then we need to look at the T-CON board to see if it is getting the DC supply to it. No luck on the service manual yet.Never stop learning

Re: Sharp LC-32HT2U Turns On Then Turns Off
Tips on posting pictures:
Clear pictures of bothe sides of the board, close up pictures of the connectors especially if they are labeled with voltage indicator and function will help a lot so we can find out what the pins are for.

Re: Sharp LC-32HT2U Turns On Then Turns Off
here are some more pics. None of the connectors had voltages labled. I was able to get the sm which will help me later when i geta chance to poke around more. The Backlights appear to go out completely. There is also a relay that clicks when it does. Will get some of the inverter board.
