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

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

The LCD panel has integrated T-CON.
The FRC is on the main board.Never stop learning

Looks like Samsung has lots of unhappy customers, Samsung should have recalled all these sets.

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?
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?
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

by Daren87Hello 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... -
by Ryan.manHello 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... -
by alltvrepairsHi,
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....2 Photos -
by smic717394Hi,
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... -
by ChrissygizmoHello everyone, Iβve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... - Loading...
