    Sharp LC-70LE732U with dps222bp, no power

    Hey yall, got a used TV for free. (Yay) then it died the next day... (my luck)..

    Pulled back cover off and tested everything best I could, but lost on things. Pin 15 bus5v (standby?) I do have 5v. Sometimes it's 2.5v. I tried to force on the board by shorting 15 and pin 14 (pwon) and it didn't make a difference. Now what I find weird is my voltage on the hot side is 60vac. At caps and everything. Fuse reads 120vac.

    Tested the common diode and even changed it and still nothing.

    So what would be a good next step to try to figure this out.

    And current prices of boards is 150... a bit out of my range, rather buy a new TV before I sink that much into something.

    Thank yall,

      Good straight on pictures of each board and one of the whole back as to see how everything is connected.

              Can check this thread, I posted 3 or 4 links to backlight testing: https://www.badcaps.net/forum/showth...99#post1265199

                  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...

                  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 LC-80LE661U 80 inch
                  by gavenb
                  Hi folks!
                  I have a LC-80LE661U that had some interesting issues.
                  Initially, it would come on and show the sharp logo and would show normal static before shutting off.

                  I started troubleshooting by disconnecting the led lighting strips and turning it on. It would do the same thing - come on, show the sharp logo and shut off. After reading, it was suggested to replace the main board. That was replaced and the same symptoms resulted. After this and some reading, the parts cannon got loaded up. I replaced the power board, same issue. Replaced the Tcon board and now it...

                  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...
