    sharp lc-60le600u 1 blink help?

    so I got this model and as soon as I plug it in the power led lights up then goes off, does not blink anymore at all, and I tried to force it on with channel down volume up like I have with other models and I cant even force it on. it has 5 volt standby which is leading me to believe bad main? any help here thanks

      You need to list the DCV readings of each pin and give us give the pin names of each pin of that white connector of the power supply board that goes to the main board. You MUST provide pin names for each pin follow by the DCV readings.
      Also provide straight shot pictures of the power supply board Top and Bottom of the whole board and closed up pictures around the connectors.

          So 5VSTBY is OK, but are you sure that ALL other pins are 0 V?

            Re: sharp lc-60le600u 1 blink help?

            yes everything else is zero, it wont power up so theres no way for any other voltages to be present. i just didnt know if this weird blink code if that is even one is known to anyone. it lights up as soon as plugged in then goes striaght off no more blinks or anything and 5 volt is present whole time, i did try another power supply i had in stock and same thing, i just figured main board. but it is possibly to force main on? with 5vstby and ps
            _on? i have never done that but is that hows its done? and just with a wire? or resistor in wire?

              Sounds like a bad mainboard.
              Did I leave the soldering iron on?

                I expect AD_DET will be >3V since it is generated by the power supply and runs off the 5VSTBY.

                What is the history of this TV? Someone worked on this before you? Hit by surge or lighting?

                'but it is possibly to force main on? with 5vstby and ps
                _on? i have never done that but is that hows its done? and just with a wire? or resistor in wire?' BTW, you do not force the main board on, you force the power supply on.

                  Yes But sorry I meant force power supply on. The history is guy brought it in said He got it from his mom and she said it had a line going down screen vertical but turned on. Which is weird cause it dont turn on. He said He dont know cause he never seen it on. I just didn't know if there was a blink code error for this model. And with light coming on and going right off? Will be going to shop now to.mess with it. Thanks

                      Panasonic ZT60 plasma tv with strange behavior and 8 blink code
                      by cloo
                      I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
                      It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


                      So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
                      After doing a factory reset this problem was gone and the picture was back to...

                      Un50cu7000 2 blink oddity *partially solved
                      by EazyBone
                      I write this to maybe help another with this TV.

                      So I aquired this TV a 2023 model. It started the 2 blink reboot problem which indicates bad panel. It was still under warranty and the repair man came by.

                      The Samsung repairman brought a brand new panel and switched my original boards to the new panel. The new panel then had the 2 blink error code. The repair guy said he has seen this and the MAIN board on this model will cause the 2 blink. He then replaced the main/power board (they are both connected) and put it back onto my original panel. Voila it worked.

                      SHARP LC-70UC30U starts up with RESET then turn off and blink 1 LONG 1 SHORT
                      by Mitike
                      Hello guys,

                      I have SHARP LC-70UC30U which won't turn on and the stand by LED blinks the 1 LONG 1 SHORT error
                      According to other sharp SM-s it is lamp error (I can't find SM for this model)
                      And yes I checked other blink error threads on the forum about other Sharp models and still can't make it work.

                      If I unplug the set and hold the POWER and INPUT buttons while I'm plug it back the set fires up and shows sharp logo and after that the Android logo and turn itself off again and starts the blinking and wont turn on again except if I do the RESET procedure again....

                      Sharp LC-80LE632U 2-5 blink code
                      by SdlewisSr
                      I have a Sharp LC-80LE632U with a 2-5 blink code. I have narrowed it down to the T-Con/Panel. I get the error if both or either ribbon cable is connected between the T-Con and the Panel. If I disconnect both ribbon cables, I get no error and the TV powers up just fine.
                      Does anyone know if this is a definite bad Panel or is there a chance that the T-Con could still be at fault?

                      Sharp LC-90LE745U 3 slow and 1 fast Blink
                      by c00lman
                      hi, new member her and apologize if this has been discussed.. tried to search and most of the result are for LC-xxLe6xx series and not sure if it's applicable to the 745U.

                      the TV stopped turning on and after the V logo stayed solid for a minute or 2, it gives the 3 slow and 1 fast blinks which from what I researched are internal communication error.

                      did some voltage measurement on the power supply out.
                      Pin 1 and 2 = 0V --> PNL 12V
                      Pin 3 and 4 = 0 V --> GND
                      Pin 5 to 8 = 13V --> UR 13V
                      Pin 9 to 12 = 0 V --> GND
                      PIN 13...
