    Any sound? Can you see a picture behind the white screen?
    Did I leave the soldering iron on?

      No sound. Control buttons don't have any effect.

        I had a monitor do this to me. It was the ribbon between the tcon and the signal processor boards dislodged.

          If yo have no sound and white screen I would start with voltage checks and look into mainboard beind suspect
          Did I leave the soldering iron on?

            There's no t-con on this (built into panel) so possible causes
            • loose ribbon as mentioned above
            • bad LCD panel voltages (the PSU board generates the various voltages for the panel on these crap Funai sets)
            • blown fuse on t-con panel board
            • bad LCD panel
            Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

              I was looking for loose ribbon first thing I opened cover. Can't find one.
              Bad LCD should have sound.
              That make either blown fuse on t-con panel (where is fuse?) or bad LCD panel voltages.
              Tom, do you think change PSU board ($45 on ebay) can fix the problem?

                It might fix the issue, but I'd like to figure out what's causing the exact fault first. Cannot find a schematic for the LC320EMXF though.

                  Can you post the panel model number? I can see the sticker on the top right but cannot read the numbers.

                      After you figure out exactly what's wrong with it you might want to consider replacing the filtering capacitors. They're probably all GP 85C caps

                        I found a working PSU board. It still gives white screen after exchanged the board.

                          Here are a couple pictures of the so called t-com. I just don't know where or if it has fuses.

                                          To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
                                          Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
                                          On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...

                                          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?...
