Power and opc lights flashing - Sharp Aquos LC-46D62U 46 in. LCD HDTV

SOURCE: power light flashes twice,then opc flashes once then power again

In all the time that you have had the tv have you applied 2 firmware updates that some of the tv's need to avoid other known issues with the lcd in the future. These firmware updates are for the main cpu PH1UU112 and the monitor MD1UA104. I don't know if this is the case for you but it worked for me. Call Sharp at 1-800-237-4277.

SOURCE: no picture no sound opc light and power light

This is very common in sharp tvs.U turn it on.U get power on light stable right?U hear a click,one or twice,sometime tv is good right?Sometime POWER light and OPC light flashes?Push the power button on/off couples times will work, picture will come on.If keep trying off/on couples time after POWER and OPC flashes,don't ever stop and never get backlight and picture.Ur Video backlight board is dead must replaced.

Fault protection mode.... More than likely you have blown Uf Caps on the PSB-Power supply board. Recap with new Uf caps. A few bucks, solder and a soldering iron.

SOURCE: will not power on, like others have had issues

Flashing power and OPC (OPC is for automatic brightness control that adjust the brightness according to room light) flashing means you have either thw power supply module or the backlight inverter module problem.

SOURCE: TV will not turn on. There are two lights in front

Sounds like your screen is broken or has been impacted. Force the television on by doing this: Unplug it and on the side of the television where the panel buttons are hold down the ch- and vol+ buttons. Then plug in the television while still holding them down. The television should come on and you see the cracks. Unfortunately it can't be repaired.

If it isn't ch- and vol + then try ch + and vol -.
