un58tu7000 reboot loop

[tmlfan]

I was recently given a Samsung un58tu7000 tv that was broken, upon plugging it in the tv constantly reboots after every 10 seconds or so

found youtube video of a same series tv that had same issue and they removed a "led dimmer" wire from the power cable feeding main board and it fixed there issue but it didn't fix mine, also if i completely unplug that wire and start tv the screen stays on

another video i found suggested pulling off one of the surface mounted chips and reprogramming it then resoldering it back on the board

any suggestions ?

Typical panel problem with these particular series.
Unplug the cable from main to panel and see if it's still rebooting.

that rebooting is probably a mainboard issue.

I got lucky fixing one of these for a friend who was pissed at Samsung. A year old and started boot looping with blank screen. Samsung told them to F off. I left the tv unplugged for 24 hours. Held power button for 30 seconds to dump excess residual power. Also held power button on remote toward unplugged tv for 30 seconds. When plugged it back in it booted normally. I immediately updated it with newer software from USB stick. (maybe update prevents further glitches). Been working since. I told them to also be wary that this model has been know to ignite the diffuser panel and melt or cause fire according to many owners online.

Re: un58tu7000 reboot loop

ok, so that usually means that your powerboard and backlights are alright.

+1 on the panel issue. Try “tape method” and you should get a picture after some playing around. Unfortunately the picture is usually degraded in some way. Ie; loss of color/s and sometimes lines

Diah was joking, for the 's who could not tell, he knows it works and has been documented for years.

to be clear, which cable, the one from powerboard to mainboard or flat cable from mainboard to panel?

Re: un58tu7000 reboot loop

Re: un58tu7000 reboot loop

So I have a replacement main board coming for this tv today, is there anything special I have to do when I plug the board in and turn tv on, does it matter if I update it over internet or should I do usb instead, and if usb where can I download the updates for usb from ?

Re: un58tu7000 reboot loop

pop it in there and try it, might work without anything else needed.

You didn’t follow anyones advice or directions. So why ask for help?
Everyone here tried to help you but you don’t listen or respond to request???

Re: un58tu7000 reboot loop

best thing you can do with any led tv, might exclude some of the newer tech, but especially these and similar series junk samsungs is turn the backlight down to as low as tolerable and keep it there for all modes, no watching on vivid mode or whatever theyre calling it these days.

Re: un58tu7000 reboot loop

I received the new main board today, swapped boards and it is still doing same thing, I figured out that also if you leave everything plugged in but remove this cable from the main to the panel also that the panel stays on
