Re: Samsung UE55KU6575U SHOWS ONLY HALF SCREEN
OK, so the LED string #1 and #2 are connected in series to form one large string.
If you look at the output Voltage as printed board, you will see that the LED power supply is rated at 200V 520mA, right now you are seeing over 300V because the power supply is not seeing the load, so you have open circuit some where in the LED circuit path.
Do you have LED tester for testing the LED strings?
BTW:
Pin 1 (1+) and 3 (1+) are tied together, they are Anode pins for LED string #1.
Pin 7 (1-) and pin 9 (1-) are tied together, they are Cathode pins for LED string #1.
Pin 2 (2+) and 4 (2+) are tied together, they are Anode pins for LED string #2.
Pin 8 (2-) and pin 10 (2-) are tied together, they are Cathode pins for LED string #2.
Your report in your post #27 does not make any sense because the pins assignment are 1+, 1-, 2+, and 2-, you do not indicate what the 1+, 1-, 2+, 2- readings are.

Re: Samsung UE55KU6575U SHOWS ONLY HALF SCREEN
Now the things goes better, the main problem is the backlight but have you noticed that also the screen matrix is defective (black vertical bar)? is it worth repairing? You better contact an electrician to install a surge discharger in the electrical circuit breaker panel.... and sell the beast fort parts...Last edited by Davi.p; 09-18-2020, 01:56 AM.Comment

Re: Samsung UE55KU6575U SHOWS ONLY HALF SCREEN
Hello and thank you all for helping me.
budm:I could not figure out what was on the label above the contact
because it's the first time for me with such tv plus I'm not a technician except I try and learn through your wonderful help.
Davi.p:that's exactly what I usually do. when I saw that this nice TV almost worked then hoped that maybe it was possible to fix for myself to use because I can not afford such stuff.
budm,Davi.p,Davi.p:the conclusion is it possible to repair or wasted time?
Davi.p:thanks for the reference i will check it outComment

Re: Samsung UE55KU6575U SHOWS ONLY HALF SCREEN
So you have picked it up for repair? Check the link well, it spoke about a broken corner after failed led replacement, not the best start, my advice after many years of this sort of business, two question to always make are if the tv is already been serviced because this reveals often bad surprices if you don't want to go mad, the second if you are not a smoker ask if the previous he was, the smell of them is really disgusting!!!Last edited by Davi.p; 09-18-2020, 01:38 PM.Comment

Hello 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... -
I’m working on a Samsung tv for my son. When I brought it home the left side of the screen was dim, right side ok. I’ve replaced the LED edge strips, main board and now the power board. The only difference is that the dim side has switched from left to right. Is there something else I should be looking at? I’ve also replaced the ground tape (Faraday tape?) from the LCD screen to the chassis. I probably have a week left on returning the parts.
Any suggestions would be appreciated.
thanks. -
Hi , 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 -
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... -
The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...
