    Re: Help with a Sharp LC-60LE835U

    Just something that got triggered. We just need to determine how to reset this. Thats all
    Did I leave the soldering iron on?

        Just tried all those and nothing, did all while plugging in and holding for 5-10 secs, and also did all those combinations while plugged in and holding in for 5-10secs....doesnt help that these aren't physical buttons, there soft keys. Are there any remote combinations that sharp uses, i know my philips uses the remote for service mode, my philips has a pin you can short on the main board to get into service mode, does sharp have any features like that, or is it just strictly keys on the side of the tv?

          I had the same 1-1 problem with a LC-52LE830U. I never did get it to turn on to reset the fault. I eventually replaced the mainboard. I'm not very patient though. What mainboard do you have?

            The board part number is: DKEYMF733FM12 but from what I have gathered the only difference between the xxLE830U series and the xxLE835U series is that the 835U is 3d. But the service manual has them together. So maybe minor differences between the two,

              Re: Help with a Sharp LC-60LE835U

              So is there any other things I can try out?

              I was looking at the schematics last night and found the chip that I think controls the power, and errors...and found a couple of pins named reset...tempting to short them, but to scared that I'll blow everything.

              I think I have tried everything known out there, might just bite the bullet and buy another, just very disturbing that every time this happens thers no reset.

                  how many LEDs are bad is it just one up on the top near the connector? I did two of these already and if it's just one LED you can get away with bypassing it by bridging it . Any more than that I would advise trying to find the LEDs you would send over current to the LED's left in a string and short them out as well.

                    I know I am 5 years late, but have you fixed the issue? I have some general questions regarding the same model and would like to know if you or anyone else could help me out.
                    Thank you.

                          Specifically what part?

                            My Sharp LC-60LE835U has the 2-5 error code (2slow/5fast blinks). I was told,

                            "That code indicates 12volt absent from panel assembly FYI main board is about $300 power supply is about $200 then labor on top it could be a costly repair just saying"

                            Can someone provide me with the solution to my issue? Do I purchase a new or refurbish MB and Power Supply?

                            Would you recommend getting my MD repaired (if that is the only issue)?

                            Your experienced advice is appreciated?

                              read some more threads in and around this type / model of set... then check to see if indeed 12v is being generated by the power supply and being received at the tcon. If can't perform some of the checks, then following the advice that you were given ($300 plus $200) is probably a good idea.

                                  Upload good clear pictures of your power supply board will help troubleshooting the problem.
                                  Is this the exact same board you have?

                                  If it is, then check DCV at PD connector PNL_POW pin and PNL12V pin.

                                      This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                                      I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                                      Hi and thanks in advance for any input you might provide!
                                      I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                                      Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                                      Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                                      Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                                      Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
