    3.3V is fine for a logic signal. Can you see an ERROR output?

        Error output is a green flashing power light on front. Once per second. This is when the tv tries to start, screen flickers and it shuts itself off with a click. It does not always do this. Sometimes it does not click off.

        I believe the every second blink means backlight/inverter issue.

          I meant an error signal from the inverter.

            Oh - as in on the screen - when you go into service mode?

            Have not tried that yet, if so, given the short time screen can be observed.

              Got it. I got sucked into the sponsored links. But, hey, I have Weather Bug now. :-)

              Thank you very much.

                Vince and all.

                Thanks.

                Sorry for the impatience. Let me look over this manual and come back with better questions. If I find the problem I will report.

                    No issues with the site. I did not read the sponsored ads close enough and installed some swanky PDF interface file that just loaded some needless stuff which I deleted along with the swanky program.

                    I have the manual in pdf form. Gracias.

                      if you can add it as a attachment then if we need to look at it we can and try to help you do it match your tv ok.

                        It's 28MB. Is that too big to upload here?

                          Nope - it won't take it. Too big.

                          Lemmie do some leg work. I am pretty much a leech right now so a little work on my part is warranted.

                          I can post specific screen prints when we start to get the cross hairs on the target.

                          Again, thanks!

                              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                              by Ryan.man
                              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                              Another TV topic!!
                              I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.

                              The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.

                              Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...

                              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...
