Hello I have a Sharp...
Hello I have a Sharp Aquos lc-60e79u. When it powers on, it will not show a picture. Instead, the power light and opc lights blink. The pattern of the blink is both blink together once and then the power blinks by it self once. And this pattern continues. Can you please tell me what this error code indicates? I have tried the channel up volume up button sequence while plugging it in and that hasn’t worked.

I feel that I can repair the tv myself. I just need to know which part within the TV has malfumctiomed by knowing what the error code means

Please allow me a few minutes to check that code....

Thanks

Are you with the tv right now? Because the buttons you pressed to force the tv on, do not appear to be the correct buttons. Can you try something right now?

Ask Your Own TV Question
Customer reply replied 9 months ago
I can

Unplug the tv POWER cord.

Press and hold Vol Down + INPUT buttons while you plug in the tv POWER cord.

Keep holding until you see the tv screen come on with a "K" in the upper corner.

Reply and let me know if you get the tv to come on (please try the process at least 3 times).

Ok i tried that several times. The screen never showed the k. The tv just simply started flashing the same code with the lights

Got it

Ask Your Own TV Question

The error code you got is for missing 13v, which is generated by the Main board (board with the audio/video jacks). It is the "brains" of the tv. I can check if that board is available somewhere if you like...

Sure. That would be great. So you feel if I replace the mainboard, this should fix the issue?

Correct.

Ask Your Own TV Question
Customer reply replied 9 months ago
To be honest. That was what I was thinking to start with. I just didn’t want to spend the $100 on a mainboard if that wasn’t the issue. That is why I came here to make sure! I do appreciate your help. I just could t find anywhere on the internet what the error code meant

Part number is ***** Hard to find new. So used or rebuilt. They are $150 on eBay used. And you can send your's in to be rebuilt for $95 at this link:

Hello Mike. I replaced the mainboard and I am still getting the same error code with no screen. Any thoughts?

Did you try this again:

Unplug the tv POWER cord.Press and hold Vol Down + INPUT buttons while you plug in the tv POWER cord.Keep holding until you see the tv screen come on with a "K" in the upper corner.
Ask Your Own TV Question
Customer reply replied 9 months ago
sir I did. It had no effect. I am wondering now if the problem may be with the power supply board. It makes a clicking sound right before the flashing

Exactly where did you get the Main board?

Ask Your Own TV Question
Customer reply replied 9 months ago
I ordered it from eBay. Tested guaranteed

Dunno... should have fixed it. Next is power board I suppose.
