    Re: Matsui M32LW409 no picture but sound

    Hi Tom,

    Or am I going over kill with the Cap? I have one that I will reuse for CP1, so just need one more do I need 10v or 25v ? If you can help with the fitting advice great if not can you recommend another one from CPC?

      Hi,The fuse and caps arrived, the fuse is alot smaller but I should be able to solder it in, the caps are way to big, I have an old PSU that I have removed some caps from the original one measured out of circuit with an ESR meter is 18.94uf. The ones from the old PSU are 11.62uf measured out of circuit. Will that be OK or do I need closer value.

      Thank you

        For the caps, you could solder some leads to them, or mount them diagonally along the board.
        I would never reuse electrolytic capacitors from an old power supply due to the principle of voltage forming, it can lead to early failure.

          Hi Tom,

          OK i will use the new ones, I did buy 16v and 25v, the new caps you say are tantalums and I have be careful with polarity I see they have a band one end so I guess that is the + end, but how do I know which pad on the Tcon to solder the + terminal to? I am going to replace CP3 with one of the tantalum caps as there is room to solder it with wires.

          Thank you

            Hi, Can some one help me please with the orientation of this capacitor I need to replace on the Tcon PCB.

            Thank you

              Can you supply a picture of the capacitor

                Hi Tom,

                OK will do, but just a thought one of the caps fails when I use my ESR meter with it removed from the PCB, the other gives a reading of 18.54uf, ESR 0.02ohms. I have found on ebay YAGEO surface mount caps, 22uf 16volt, would they be better suited to replace the pair from the TCON or replace the one that indicates 18.54uf and one new 22uf 16volt one? or the ones I have that need to be in correct orientation?

                  Hi Tom,

                  Picture of the 16v 22uf cap, I have a 35v 22uf one as well. Or shall I do what I suggested in last post?

                  Thank you

                    That is quite big.
                    Can you link to the YAGEO ones?

                      Or I have a TCON from another make and model of TV that I could remove caps from assuming they are the correct value?

                          Hi Tom,

                          I fitted the two caps and replaced the fuse and I get a picture but see the attachments as it looks awful.

                            Hmm. Looks like something else on that T-con is fried also.

                                        Any Vestel or Philips remote will work.
                                        You WILL need a remote to access it.

                                          OK Would it not be easier to just replace the TCON? or do you just think it is a setting issue? if so what settings an I looking at or adjusting

                                            Hi, I have a Samsung UE50TU with:
                                            - sound and backlight, but no picture
                                            - when it arrived, it had a picture for a few seconds
                                            - it keeps rebooting
                                            - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                                            - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                                            - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                                            - without cable between mainboard and lcd panel and with a jumpered...

                                            I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started β€˜fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                                            I ordered a supposedly β€˜new' Tcon board this time, and

                                            Hello everyone,
                                            Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
                                            The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
                                            He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
                                            I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
                                            Anyway I still fully expect that there has been something seriously damaged...

                                            Hi all

                                            I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



                                            Symptom:
                                            No picture no sound.
                                            When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
                                            No sound at all.



                                            What I tried:
                                            1. I tried unplugging the left or right ribbon...

                                            so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

                                            i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
