Sharp OPC Codes Question - EASY!!

[kevinjo]

I have a Sharp LC-C5255U and can't find error codes but found for a similar model like LC-52D64U. The OPC and Power light lights up at the same time and then the Power light will flash by itself another 2 times. Is this a 1-2 code or a 1-3 code? The 64U says it is a 10v failure for 1 opc and 2 power flash. I do not have a 1-3 code data if it is that. Symptoms is it tries to turn on 3 times and gives up with the code. No back and no pic. thanks. If you have codes or service manual..lmk. Tanya had nothing.

If you would have posted some pictures You may have had more help. If it IS like a LC-52D64U I would check the inverter transformers, I had one once that had a bad transformer, try checking the resistance of the windings and compairing them, if one is open that would shut the set down. Does one of the inverter boards look like this one? The manual for the LC-52D64U can be found online

Re: Sharp OPC Codes Question - EASY!!

looks like you have a 3-1 code (COMMUNICATION ERROR).
Try unplugging and then hold down vol- and channel+ while plugging back in and see what happens.

Well I know you guys like pictures but I had no idea what picture you would want? First thing I did was that I did get a new set of inverters as I know that's a common failure. Same result and yes they do look like the picture above. Communication error? Would that be with the main? I did order a new main and haven't tried yet as it just came in. I know these sets have bad bulbs also but didn't seem like a 3-1 code would come from bad bulbs. Hopefully the main will work and will post in 12 hours on that. The only other thing I could think of is TCON? The customer said he changed out the power which to me tests fine. I do get the 60 volts to the inverters. The TV cycles 3 times and then shuts off. Not light, video or anything. No response from on/off buttons! Tried to force on via Ch- and vol - but that did nothing. Thanks.

Service manual may be close enough for the error codes:

Pictures of the whole back side of the TV will help.
Lots of boards used in the same model as your and in LC52SB55U.

Re: Sharp OPC Codes Question - EASY!!

Thanks a bunch. I didn't have the 3 blink power code page. Sounds like a main board and will have to see if I can repair it. If not..I do have a back up main to use. Will add to this later. Thanks for posting these pages.

Re: Sharp OPC Codes Question - EASY!!

It was the main board. I was unable to determine why. There was only 2 caps SMD type and both tested fine so I guess the issue was somewhere in an IC? Thanks.
