Re: Samsung le46b530p7w
Yes LX6503. Please check pin 7 voltage, red probe on pin 7 black probe on chassis. It should be >2V continuously if backlight on.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung le46b530p7w
That seems too low. Does it increase when the TV backlight works? You could solder a wire to that pin to make monitoring it easier.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung le46b530p7w
If you checked ON/OFF and it's steady it wouldn't. Sounds like you have a thermal issue. Have you tried heating bits of board up and seeing if you can get it to fail?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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... -
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 -
HI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when... -
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... -
Have a Samsung UN50NU7400 which shows a boot screen and a screen saver if left on long enough but no picture ?
Would a moving screen saver confirm that the panel is ok or it could still be a panel issue ?
