    Sharp Aquos lc42d6u power and OPC flash once together, then power light flashes twice

    This belongs to a friend of mine that has really helped me out so I want to try to fix this for him.

    Anyways into it the power and OFC lights blink once together then power two more times. It cycles though this pattern over and over when you plug it in and press power. There is random clicking from the relays every few cycles of the light blinks. My friend thought it was a bad power board. I see two of them but there is no obvious problems.

    When I googled the issue I got several videos on force starting it holding the vol+ and channel down and that did nothing. I saw another youtube (on a different model ) that if you hold input and vol - it would hard reset the firmware. That did nothing either.

    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 LC-40LE814E does not turn on 2 flashes
    by Egidio85
    hi, I have a sharp tv model LC-40LE814E with DPS-126CP-1 A power supply.

    the tv initially turned on, displayed the image for 10 seconds and then turned off. so in a loop until the power was cut off.

    reading the classic optocoupler problem I changed the mounted cosmos with SHARP PC817 recovered from other boards.

    now the TV turns on for 1-2 seconds and turns off giving 2 flashes in the front LED.



    to avoid banging too much I preferred to take an identical tested and working card (or so the supplier says)

    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...
