I bought a sharp Aquyous tv model no.LC-37AD5E-BK 37". After plugging the tv worked for a couple of days and the power went off. The technitian traced the problem to a power IC P/NO. TD12250P. All efforts to get this ic in Nigeria proves abrtive, how can you assist if this is the problem or can you offer other suggestions. Pls reply me thru my e-mail as i will not be available to wait for your reply now. ( [email protected]) Best regards.

Sharp LC 22L50M BK Operation Manual

You could open up the TV and look for signs of burnt components then try to replace the components or try to find a replacement for the entire affected board on ebay or something. If you can find out what the problem is maybe the service person will lower there price. $600 does seem very steap, it should be something closer to $60 an hour with maybe the first $60 as an estimate.

Check componets around MCU (crystal and other capacitors)as well as bad solders on the mainboard.

This problem very common in sharp tv.The POWER,OPC flashes.First turn on have power LED indicator light stable at all? Tries the power again couple times will have backlight come back on,than it will work.Not at all more than 5-6 times than ur main turner signal board is the problem,must replaced.

Your power supply unit needs servicing on some part replacements. bad capacitors, voltage regulators, hi-watt resistors,....etc

it is 99% certain that what needs to be replaced is the power board.

That's the #1 problem across the board with TVs that work for some time and then start behaving like you describe.

If you know what a scredriver is I'd suggest you do it yourself.

You can seek for a new board on eBay or through Google. I'd search for "LC-37GD6U power board".

If you don't find one you'd start searching for other similar TVs and compare the pictures of the board with what you pull out of yours.

Of course you can have a technician do all that for you for a $150 more.

This is the best place that's near the manual you need.
They have the LC32D44E manuals, but not the "BK" at the end. I think the "BK" just means BLACK.
But, I think it will work for your TV.

i have had to replace the hdmi input board on these units to fix them.

This same thing happened to me, but not until I fiddled with all of my remotes, trying to see if it was an input issue, battery issue, etc. I finally unplugged the tv from the wall and plugged it back in. Nothing. Then I went to take 5 minute ****. When I finished, the Power & OPC lights were blinking, and out of sync. I pressed the power button at the top of my TV and got a picture.
