    Sharp Aquos PN-LE801 shutting down

    Hello,

    I have a Sharp TV that is powering on with backlight and picture then after 5 seconds it turns off. The front LED blinks after shutting down.

    I checked the power board voltages and have 12v, 5v and 3.3v on the standby when first turned on then the STB goes down to 1.4v after a second.

    Where should I go from here?

    Damaged, dry capacitors in the power supply of the standby power line. You have to measure ESR and you will know.

      I have checked them all with the ESR meter.

        In that case, the protection is triggered and the TV goes into standby and blinks showing the fault code. Usually it is a faulty backlight diode in the led strip.

          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...
