Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Hard to get started when powering up to watch.


definitely, something wrong with it. TV shouldn't take more then a few seconds to start, I suggest, while it still under warranty, give Sharp a call to get it fixed.

Set up only visible for 2 seconds, then black - Aquous lc-37d43u


Unfortunately I can promise you that you CANNOT repair this. Your power and opc lights coming on, but the tv is not coming on. That is a issue within the tv. Give sharp a call and they will have somebody come fix your tv free of charge, if they cant fix it, they will replace it for free. That is the only thing you can do. Sorry bro

No POWER


How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)
