Re: UN55KS8000 T con or screen?
Could be tcon or bad connection, really hard to tell sometimes, boils down to getting it pretty cheap in case it's a type of panel problem that can't be fixed. -
Re: UN55KS8000 T con or screen?
This set has no t-con , the LVDS cables go directly to the display. Disconnecting one by one does not help either with this tv, that could only be done with the tv's with a t-con.Comment

Re: UN55KS8000 T con or screen?
Could be bad tab bonds, check youtube for tab bond testing and repair, must be at least 100 videos on the subject.Last edited by nomoresonys; 06-04-2019, 09:47 AM.Comment

Re: UN55KS8000 T con or screen?
Thinking 75 bucks would be a maximum, then if it's not fixable you might recoop by selling parts but 180 is way too much to gamble on.Comment

Re: UN55KS8000 T con or screen?
The LCD panel has integrated T-CON.
The FRC is on the main board.Never stop learning

Re: UN55KS8000 T con or screen?
They were asking $240 lol but could possibly get it lower. Looked like an easy fix but this time I'll pass.You live and you learn right?Comment

Ok, your picture looked just like the one in this ebay ad: https://www.ebay.com/itm/FOR-PARTS-O...-/123738852757Comment

Re: UN55KS8000 T con or screen?
Looks like Samsung has lots of unhappy customers, Samsung should have recalled all these sets.

Re: UN55KS8000 T con or screen?
Any idea what the problem ended up being with this one? I got a TV that looks exactly the same. Have you tried replacing the main board, or is this a bad panel?Comment

Re: UN55KS8000 T con or screen?
Seems the fix is to replace resistors and ESD / TVS Diode pack
The video shows removal of the diodes.. I'd like to replace them (if I can see the darn things) and the IC is labeled 4263H and I can't seem to find that.. Any idea what this chip is?

Re: UN55KS8000 T con or screen?
you have to remove the long metal piece to expose the boards, like in the video, those resistors and any diode packs are on the long thin panel driver boards.Last edited by nomoresonys; 12-31-2022, 12:00 PM.Comment

Re: UN55KS8000 T con or screen?
They are.. I just don't know what to replace them with. The creator of this video simply took them off.. I would like to replace themComment

Re: UN55KS8000 T con or screen?
ok, I thought you were wondering where they were, when I saw the picture of the mainboard there, lol.Comment
-
Re: UN55KS8000 T con or screen?
No problem. The area has the flex cables, and using hot air, can cause more of a problem replacing them.. that's why I see they simply removed them. Let's hope there isn't any large transients on these circuits, and I'll go with replacing the bad resistors only. fingers crossed.Comment

Re: UN55KS8000 T con or screen?
1206 100 ohm, maybe get 4 or so, replace the resistors, if no joy might need to remove the diode packs, might only need to remove one diode pack maybe both, might both be ok.Comment

Re: UN55KS8000 T con or screen?
They are 51 ohm resistors not 100, they are marked 51R0.
The diode is ESD7004.Comment
-
Re: UN55KS8000 T con or screen?
yes they are, the people replacing them were using the 1206 100 with success, that's what I would use but op can use whatever he wants of course.Comment

Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Hi,
i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.
Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.
Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?
Appreciate your help.... -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
Hello 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...
