    Sharp PN-E702

    Good Morning,
    We have a Sharp PN-E702 that loses backlight after 20 seconds. We are trying to rule out wheather its the display or the supply. On the 14 separate supplies we have about 180v supplying the screen. On the return from the screen we only have between 1v and 1.7v. After disconnecting the return voltage on the 14 separate pins the voltages range between 70v and 90v. Any help would be much appreciated.

    Best Regards Peter

      Sounds like a bad Led in the screen to me. You will have to take the Lcd panel apart and test the Led backlights.

              Thats what we were thinking as well,,unfortunately due to the size of this beast its a real pain to do without risking cracking the screen.

                  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...
