    sharp aquos LC-32D44U

    the problem is that I have no picture and sound. when connecting the TV, there is a relay on the board of the power supply that has 2 click recovery declic this product 4 times, after these tests, the power light and opc blink together once, and after the power light flashes 2 times, repeat this sequence it.
    NB when I reset the TV by pressing simultaneously on the volume - and the input
    The tv work perfectly. thank you

    Have you checked the bulb error counter under the service menu?

                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 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....
