    Sharp Aquos LC-32DH77E Static band

    Hey there everyone,

    I'm having an issue with my tv which is used for console use only. The static appeared after disconnecting my PS4 for a week when I connected it on my return.

    I've tried 2 other hdmi cab,es, tried the PS4 on another to (which is fine) done various resets on the tv including an "initialise"on the manufacturers menu.
    Taken the back off to check for loose solder points and all ribbons plugged in correctly. Wiggling all hdmi ports doesn't affect the static at all.

    The only thing that makes a slight difference is unplugging the to for a while and when plugged back in the "bands" thickness is much slimmer, but this soon returns to the same as the image within a minute.

    As you can see any menus show up above the static. I hope this helps to identify the issue and hopefully a solution!

    Thanks for any help!

      Almost certainly an issue with the main board on the TV. I think I've seen something similar before.

          Ok thanks,

          Any recommendations on sites for cheap replacement boards? I did google thinking I might have to replace the MB but they're so expensive! And for Ā£100+ I might as well invest in a new tv.

              I use spare2repair who are pretty good.
              Willing to help but I'm no expert.

                  They don't stock my model.

                  Daft question, would I be able to use another Sharp MB for a similar model but not exactly the same? That website above has a few other Sharp 32" MBs and wondered if any would work?

                  Also I'm assuming there's no way of fixing the MB? Does it have an option to flash it in hopes that will fix the issue?

                  I'm not sure how similar TV MBs are to PCs in what can be done to them and their compatibility with other components of the TV

                      It's likely anything from the same model generation e.g. DH series will work but unlikely any Sharp main board will work. May even be possible to use 37" and 42" boards.

                          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 40ā€ 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 Iā€™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
                          9-10-11-12...

                          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....
