Luquid crystal television set - 125-240 AC

You have basically 2 options available to you:

1) Contact Sharp at the address you listed and they will instuct you on what you need.

2) Purchase a power conversion transformer. This will convert the 240AC to 110 AC and you can use the standard 110 AC cord.

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)
