As title states, sound but no picture. I have done all of the rudimentary troubleshooting steps- flashlight test no lights visable. Checked Source and it is correct. Tried different, verified good HDMI cable, swapped satellite receiver boxes etc and no luck. I see lots of kits with replacement boards, but before I start throwing parts at it I'd like to know if anyone has suggestions. The brown power board has a couple of spots that are suspect. They are a darker brown circular color. Not sure if that is just from normal use or if something may be burnt. Not sure if a suspect power board is capable of no picture but still having sound or not. Any help would be appreciated.

Re: Samsung UN55J6200AFXZA Sound but no Picture
If you have no backlights, you likely have bad backlights especially in E, H and J model year Samsungs. -
Re: Samsung UN55J6200AFXZA Sound but no Picture
When you unplug cable between main and power board do you get backlights?I assume no responsibility for any stupid suggestions I might post.Comment

Re: Samsung UN55J6200AFXZA Sound but no Picture
how bout some good clear pictures of all the boards and one of the whole back as to see how everything is connected and a good one of these burn marks you speak of.Quit because THIS SITE LETS A ROGUE MEMBER TYPE ANY GARBAGE HE PLEASES AND THE POWERS THAT BE NEVER DO ANYTHING ABOUT IT SO HE NEVER QUITS.

Re: Samsung UN55J6200AFXZA Sound but no Picture
When I took the back panel off, all cables seemed to be secure to my eye. Attached are pics of the power board front and back. If it is the back light or lights, do they typically all go out at once or a few at a time?Attached FilesComment

Re: Samsung UN55J6200AFXZA Sound but no Picture
What is the output voltage of led driver? If a high voltage appears, and then begins to fall, then the backlight (Leds) is not working.
You have a backlight, like a garland, one LED burns out or breaks, then others stop working.Attached FilesLast edited by lotas; 10-10-2022, 05:38 PM.Comment

Re: Samsung UN55J6200AFXZA Sound but no Picture
Samsungs don't have protection shutdown. LEDs will continue to burn out until the screen is too dim, one fails open circuit acting like a fuse or there is damage to the power supply.Comment

Re: Samsung UN55J6200AFXZA Sound but no Picture
you have at least one bad solder joint, picture isnt real clear, theres one just above the word cold, look them all over closely, reflow any that look a little suspect, careful not to bridge anything with the solder, examples of bad joints in case anyone needs it: https://www.google.com/search?q=bad+...ih=607&dpr=1.5Quit because THIS SITE LETS A ROGUE MEMBER TYPE ANY GARBAGE HE PLEASES AND THE POWERS THAT BE NEVER DO ANYTHING ABOUT IT SO HE NEVER QUITS.

Sorry for the delay, work gets in the way. I appreciate the comments and suggestions thus far. I did the test as described above, no backlights visible.Comment

Re: Samsung UN55J6200AFXZA Sound but no Picture
No, I guess I missed that post. But looking back I can see where it was mentioned. So, speculating here, once solder joints are repaired if I do the same test again and the backlights do not turn on, what does that mean?Comment

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 ‘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... -
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... -
Hello all,
This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where... -
Hello all ~
I’m working on this Samsung 60” LED and purchased a new main board a couple of days ago that did not fix the 5 blink issue. The original main board’s HDMI ports (all 4 of them) failed to work and no amount of reflow remedied that.
This 5 red light blink code on the front panel LED is followed (about 15-20 seconds afterward) by an automatic reboot, and results in 5 more red light blinks. Then the entire cycle repeats itself indefinitely.
No picture. No sound.
I tested all the voltages coming out of the power supply...
