Re: Sharp LC-C5262U failed, what is this code?

Thanks R_J for the link. That service manual covers model LC-52D62U and mine is LC-C5262U. Very similar but I wonder what the difference is.

If I'm reading the tables (bottom of page 6-17) as intended, they describe my error as this:

"Initial communication from the main CPU is not received. (After cancelling the reset, request for the monitor model No. is not received.) Communication line failure or main CPU start-up failure."

Re: Sharp LC-C5262U failed, what is this code?

No, I don't have any type of schematic or diagnostic guide yet. Hoping I can find one. I'm not getting any backlight, so perhaps the problem is related to the power supply board and its CCFL outputs.

Thanks.

I don't notice any difference if I do that. How long should the vol- and ch+ buttons be held after plugging in?

I've got the back panel off and I can see a red LED on the mainboard. When I plug the TV in, there is a click and then that LED blinks once a second for 30 seconds, then another click and another 30 blinks, and two more cycles of this before the mainboard LED goes out and the front panel LEDs blink as I previously reported.

Hi all,

I have a Sharp LC-C5262U that just quit on me after many years. The display and sound went out while watching a program. The power light stays on but the TV is unresponsive.

About 2 minutes after plugging it in, I get what I presume is an error code but I have yet to find out what this means. The Power and OPC LEDs blink together once, then the Power LED blinks twice more.

Hi all. I'm Tom and I'm here to hopefully get some help in diagnosing a failed TV.
