    Is this white-washed screen caused by a faulty T-Con board or panel? Sharp Aquos c70le735x

    Hello esteemed gentlemen. I have owned this LCD TV since 2012. The only repair was the replacement of the PSU a few years ago. Apart from that, no issues. Recently, all was working fine until I switched on to see it appear as so. The day before it was working fine. There is sound. Could this be a T-Con board issue? If not, what could it be? Thank you.

    i suppose it to be Lc-70le735x / Lc-70le735.. anyway it seems somehow a reduced vgl, maybe a tcon probem, maybe screen stripe board, disconnect tcon outputs one at a time and show the results, photo is better than video please..

      Thanks for the reply, Davi. I have a picture taken of the screen. This was when I switched on the power. All parts are connected here. I have not opened up the panel.

          Davi, I will be opening up the TV over this weekend. I will definitely get back to you with the findings.

            Not to insult anyone's intelligence but once saw an LG do a similar thing, unplugged it from the electrical outlet and let it sit for half hour, plugged it back in and to my surprise i had perfect picture...go figure.

                    Driving a Sharp TCON/panel with a universal main board
                    by advant
                    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...

                    LG 82UN8570AUD ~ TCON or PANEL?
                    by kca
                    Hello all ~

                    Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

                    When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

                    I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

                    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 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...

                    TCL 50S535 bad tcon or panel issue?
                    by x_orange90_x
                    Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

                    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
