    Re: SHARP LC-40LE811E help

    Very strange, it looks like a bad panel for sure. There really are only three parts in a tv which could cause such a failure. The main board, the T-con board, and the screen. You have already eliminated the screen, so it must be one of the boards inside the set. Unfortunately I am not sure how you would determine which is which at this point.

      If you disconnect one of the tcon to panel cables do you have a clear half picture. Then reconnect the panel cable and repeat for the second cable.
      I think it's a mainboard problem.
      Willing to help but I'm no expert.

              Is the replacement LCD used or brand new? How much did you pay for that 'NEW' 40" LCD panel?

                  Panasonic SA-MAX770PU SMPSU board fault....
                  by Rictech
                  Hello everyone. 😀

                  As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
                  Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

                  Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
                  This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
                  There are no devices that have exploded or otherwise show signs...

                  ESR meter came to the rescue again today with a PLC I/O card fault
                  by sam_sam_sam
                  I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
                  I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not

                  One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference...

                  Strange fault on Lenovo ThinkPad E14 Gen. 2
                  by cazi1001
                  Hello,
                  I have a strange fault with a Lenovo ThinkPad E14 G2 (Board No. NM-D011 Rev. 1.0).

                  The first Problem, which I fixed already, was a dead TPS65944AD (USB Type-C) controller. After I fixed this fault, all functions working fine and the notebook run very well with the charger and battery.
                  On the next day, I tied to start the notebook with the battery, but nothing happened. I started with the charger and on windows, I saw, that the battery was empty. And this was nearly impossible, because the battery was charged. I disconnected the battery and found out, that the board...

                  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...
