    Sharp Aquos LC-70EQ10U

    Hello All,

    After following a couple of the threads on here, attempting to fix my LC-70EQ10U, I am at a loss and looking for some help.

    I got the TV for free, it does not have a remote control. I thought it was the power supply, so I replaced that as a first attempt. I then got an LED tester to make sure those were working and they are! I try to turn on the TV and literally nothing happens. Tried resetting it by doing the input and volume down trick, and all I get is the 2-5 blink code.

    I followed the threads on here and took apart the bezel, removed any plastic, and re-seeded all the ribbon cables and their connections. Put it back together, still nothing. I've tried removing any number of combinations of ribbons from the T-Con to get some action on the screen and still, nothing.

    I was wondering if anyone had any thoughts, I feel like I've tried everything but I am still holding on to a little bit of hope that I can get this thing fired up!

      Google and you can find the service manual. 2-5 says its Panel_Pow error. No PNL 12V. Not sure if that's the TCON board voltage supply.

          Post some good straight on pictures of each board and one of the whole back so we can see how they are connected, try test #3 below if you have a multimeter, try to do it just as instructed.

              Ok, then check if there's about 12 volts on each side of the tcon fuse, black - probe on chassis metal ground, red + probe on each side of fuse. All you need is a simple digital multimeter, they are about 10 bucks or so at the big box stores here.

                  Looks like it could be the same kind of thing as this:

                      Sharp Aquos LC-70C6400U Half Screen Dark
                      by scubacamper
                      I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
                      Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
                      when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...

                      Sharp Aquos Lc-80LE757U flashing Sharp on screen when plugged in
                      by sefoster
                      I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp...

                      Sharp Aquos LC-40UG7252E LCD TV burn in?
                      by jonah1024
                      Hello!

                      I'm a few days old into this TV screens repair universe so please bear with me.

                      Recently, and all of a sudden my 40” 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but I’m shore this is not an OLED.

                      - I did the classic unplug and hold power button to discharge the caps but it didn't help.
                      - I did a factory reset as well...

                      Sharp Aquos LC-60LE635E three blinks
                      by klassic
                      Hi community,

                      I will describe my problem with a TV in those short following terms to be the most precise :

                      What i have :
                      Sharp Aquos LC-60LE635E
                      power board DPS-162KP-1
                      main logic board QPWBXF733WJN2

                      symptoms :
                      white led light logo at startup,
                      after 2 minutes, blinking 3 times a row, repeating
                      no backlight (and apparently no picture, checked panel with flashlight)
                      no startup sound

                      powerboard investigations :

                      1-2 PNL : 0v
                      3-4 GND
                      5-6-7-8 UR : 13.15v

                      Sharp Aquos LC-32LE600E, No 12v as no PNL_POW
                      by foxyUK
                      Can anyone help me diagnose this? Almost not worth bothering with, but it has 'sentimental value' for the owner. I'm no TV technician, but dabble a bit.
                      The TV has standby power but no reaction at all to switching on or reboot steps, No flashing lights or response to menu button. All voltages on the power board are correct apart from missing voltage on pin 12 of CN7003.
                      There is 13 v on U7053 but no 3v signal to switch it on. I don't really understand whether the 3v should come from U7401 in the standby control area, or (as suggested elsewhere) from the mainboard via pin 12....
