    Re: vx37l no picture no sound

    I had to have the local tv repairman solder in the new regulator and he said i probably didnt need the ceramic cap and told me to try it without it. I dont see any interferance and the picture looks great. He also replace the wire with the 2 ferrite beads and replaced a bulging cap on a board for a 19" westinghouse and charged me $30. bucks and now i have 2 working tv's. I tryed to do the soldering but being a total rookie i couldnt get the solder to stick to the board. i touch the solder to the tip and the solder forms a ball on the end of the solder itself.
    Today i picked up a 32" westinghouse that has sound and image but the screen is black and a 32" dynex that works but if i move the tv the screen will change to vertical lines so i will be scouring this site for info. and maybe asking for advice.

        That kinda sounds like the solder you've got doesn't have a flux/rosin core, or you're using RoHS compliant (leadfree) solder with a very low wattage iron (doesn't get hot enough)

            I would never use lead free solder in any of my repair, if you have Weller soldering station, you can get 800 degree tip instead of the 700 degree as supplied with the iron.

              Re: vx37l no picture no sound

              Thanks Budm, Thats the advice i like to get. I live in a town of 18,000 and so the local resources are limited. I found this solder iron at home depot and i will now get some lead solder. I am a total rookie but if i can get properly equipped it would eliminate alot of frustration.

                Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                by TR103
                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...

                Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                by Mgiffune
                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 ‘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 ‘new' Tcon board this time, and

                Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
                by Ierwin
                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...

                Samsung UN70NU6900F no picture and no sound
                by jchang
                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...

                what i went through dealing with my mobo with dead onboard sound!
                by ChaosLegionnaire
                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...
