    Sharp lc-70le755u flickering picture/backlight

    Hey everyone! I inherited a "free" Sharp lc-70le755u with a strange picture issue. To try to explain, the picture flickers before what I think is a power saving mode kicks in and reduces the back light. I took a short video and uploaded it here:

    I'm thinking it could be the TCon board, but possibly the panel. Thought it might be worth it to post here and see if anyone has a better idea before I try throwing parts at it. If its the panel (which I hope its not), then I won't bother trying to fix it.

      Flickering image is a bad panel. Doesn't look like the backlight is flickering though it will be easier to tell with a proper video image. You can try blocking pins on the bad side or as a last resort, rip off the side tabs or side boards on the bad side once you identify which side is good.

          UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!

          this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
          i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
          unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
          according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

          Sharp LC70LE755U - Intermittent backlight flickering and loss of sound.
          by TheForgottenKing
          Hello everyone, first time posting here so I hope I'm doing everything right.

          I just came into possession of a Sharp Aquos LC70LE755U. It was free for me, so with the stand and power cable I only have $30 in this. As such, I'm trying to repair it for cheap.

          It works most of the time perfectly, except for an issue with what I think is the power supply. After anywhere from 10-30 minutes of usage, the screen backlight will flicker briefly, and the sound will completely stop working. The sound doesn't start working until I unplug the TV, wait a few seconds, and plug it...

          Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
          by TR103
          Hi, I have a Samsung UE50TU with:
          - sound and backlight, but no picture
          - when it arrived, it had a picture for a few seconds
          - it keeps rebooting
          - without ribbon cable between the two panel boards, it does not reboot but I have no picture
          - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
          - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

          - without cable between mainboard and lcd panel and with a jumpered...

          Sharp 80” long short flash backlight error - Help
          by Superbee_dad
          Hello Sharp TV experts
          Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.

          > I checked voltages on the power supply board and they all check out .. including 3.28 volts at the error pin.
          > There is power to the cpu and T-CONN and no faults found there. The cpu has a flashing...

          Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
          by Mgiffune
          I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

          I ordered a supposedly ‘new' Tcon board this time, and          ...
