I have a 60 in Samsung UN60HU8500 4k.. has no image has sound and backlights,without pausing I bought a T-con after my research, there is a lot of Samsung's doing this.. so I installed the T-con and same problem blank screen .. not giving up...I powered off the set re installed the right ribbon to my left, there are 4...pulled up the ribbon retaining clip re installed... then the pic started working,!!! So everything is great because I only paid 150.00 for the tv .. installed the tcon metal shield powered the tv on... no picture again back to square one.. after further checking in installing the ribbons to the t-con over and over the picture never changes... so I looked at the one ribbon causing the problem and there is the problem some of the gold contact was missing... and checking the the ribbons comming grime the mainboard... I found the same problem... BE CAREFUL WHEN REMOVING THE RIBBONS!!! USE A MAGNIFYING LENSE...now I had to order the damaged ribbons !! I will return with the results... I'm just wondering if people look at them closely??

Interesting. Looks like cheaply made ribbons. Let us know if this solves the problem.Did I leave the soldering iron on? -

by kcaHello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
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!

by iglitareHi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
by x_orange90_xJust bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

by mecha1166KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen. Already tried reset POWER/VOL-. Anyone else have this problem? Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help.
