Re: Sharp LC-C5262U Power & OPC Lights Blinking

It was the T-con board. Replaced it and its all good. The original mainboard ended up being ok. Thanks to all for the help!

Re: Sharp LC-C5262U Power & OPC Lights Blinking

I can not hear any sound,.... I don't know how to change sources I tried using the input button on the top of the TV , as well as the remote... nothing.

Although,.. I turned the TV on with the T-con unplugged and then plugged in the T-con board while the TV was still on. As soon as I did that, the TV clicked and gave me the blinking lights.

I guess it sounds like there is a problem with this board

Re: Sharp LC-C5262U Power & OPC Lights Blinking

Not really sure how to check for power at the boards,... I have a digital multimeter, and I have a friend that can assist me. I posted pics of the LCD controller board,..I assume the grey is the power cable to the board, and the ribbon is the data? Where do I check for power and what setting do I put my muiltimeter on? (Sorry, but I am bit new to this part)

Secondly,.. I unplugged the grey cable to the LCD controller and turned on the TV. No more blinking lights,... It seems like I have back-lights as the screen...

Re: Sharp LC-C5262U Power & OPC Lights Blinking

I've tried all the following (all on TV not using remote)

vol + & ch + then POWER. - Nothing,... still blinking the same.

Input & Vol - then POWER - Nothing.... still blinking the same.

Vol - Ch - then POWER. - This is the only time its different.... It clicks on,... I don't get any picture or sound,.. but I do see the LCD back-light come on. It just stays that way until I unplug it. Then I plug back in,.. turn on,.. and I get the same blinking codes again.

Don't...

See attached pics of the old and the new mainboard from ebay. All the numbers are the same except for the number in the white box which I am told is a production code and will be different on each one (hopefully).

New board from ebay is on left in the pictures below.

Both boards are KD934 Ver 4. The ebay seller is very friendly and is also willing to take back any parts that do not fix the TV. He told me that this board came out of the same model TV I have (LC-C5262U) that had a broken screen.

So my problem is that I get POWER and OPC blinking lights. The TV will not power on. When I plug it in I get a click,.. then a few seconds later it clicks and I get these lights: POWER & OPC blinks twice, then OPC blinks 3 more times.

I had a sharp technician diagnose the tv. He tried a bunch of different codes on the keypad, until the last one finally worked, and we got sound, it looked like the backlights on the sides still worked, but the screen was black and not even the menu would come up. Once he saw that, he said it was the main-board. They wanted 500 for parts and labor...
