Came across a 75" QLED TV with restart-backlight no boot and it was headed to the dumpster. Asked the owner to let me have a crack at it. They said the TV went out during or soon after a thunderstorm. I noted this but didnt out too much stock into it as it could have been anything.
VERY big TV and i was worried about the display cracking during the moved as well as the repair but it was alright as i try very hard to handle with care.

Hi All,
Need help.
I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.
So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard.... -
I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down

Hello,
I have a display problem (bad size and color) on a Samsung U28E590D and i'm wondering if someone have access to the service manual for this monitor. I used a faulty Lenovo thunderbolt hub connected to it and now i suspect a problem on the HDMI part of this monitor. The main PCB board part number is: BN94-10748G.
Thanks for your help.10-02-2023, 05:30 AM -
