Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen
no, i asked which code he has searched, if the good one or not.. BN94 is the good one..
my curiosity, has someone done house works , using heavy tools, drills , demolitions and so on the days the defect happened?Last edited by Davi.p; 02-24-2023, 07:06 AM.Comment

Not that I know off. After getting so much information from here, my good guess is that he ( the local tech )has probably tried to fix it by working with the u ribbon cable and eventually totally damaged the main board. That's why my tv went from normal image but with horizontal stall lines to full blue.Comment

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen
yes, clearly a panel defect, the same and today old gate driver defect.. only masking tape can work
you must mask a series of 8 subsequent pins on one of the two flat cables starting from the outer side, at randomLast edited by Davi.p; 02-24-2023, 10:40 AM.Comment

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen
I understand. Going from left or right to the middle of each cable. 8 at once. Should I try that before swapping the main board ?Comment

I will have to try your method of masking the 8 subsequent pins tomorrow.
Picture 1 - without removing the flex ribbon
Picture 2 - with the flex ribbon removedLast edited by gbbradshaw; 02-24-2023, 03:13 PM.Comment

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen
I am afraid I have only removed the u ribbon from right side as I ran out of time to do so for the left side aswell
I will try this tomorrow. So patch 8, then another 8, only from on side of the u ribbon, until it gets fixed? Please look at picture.Last edited by gbbradshaw; 02-24-2023, 03:44 PM.Comment

Despite what one member says, lines on the screen even lots close together doesn't instantly mean a bad panel, it could be as simple as a bad cap on panel driver boards which technically is a bad panel, or cap on mainboard or cap on powerboard or something else on one of the boards, those who jump to conclusions quickly, NEVER make good troubleshooters AND they are sooo f@#king irritating.Last edited by nomoresonys; 02-24-2023, 05:05 PM.Comment

I completely agree with you, but there's nothing else I can do but try things. So far, the only thing that worked was changing the MB, now I got back to having an image. I would also change the caps on the lower boards where the the flex ribbon connects, but honestly I don't see which caps are they or the name, so I can order some.Comment

No it's not you Gbb, it's that goofy guy that keeps crying panels shorted every time he sees a line or two, which it could be a bad panel but could also be a LOT of other things as well, we all know his name.Last edited by nomoresonys; 02-24-2023, 05:07 PM.Comment

by mar1inHi everyone,
I've got this Samsung here that would be stuck in a boot loop.
After opening up and doing the tape block method, I was able to get it to turn on and play sound from the HDMI input, but with a blue screen.
Does that mean there is another combination of pins that I need to block in order to get a picture, or is there something more serious, faulty mainboard or faulty panel?
Thanks in advance -
by MgiffuneI 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... -
by ChrissygizmoHello everyone, I’ve 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... -
by ChrissygizmoHi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
Ive eventually managed to get it on and working but it's very temperamental...
The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...05-26-2024, 12:05 AM -
