I have tried again, with all remotes draining power etc etc only the power button will turn the TV on. No other functionality on the TV works at all. Shows input source at startup and all clicks are unresponsive. Except for power button which is super friggin odd. This is all with the backlight off.

Hello Team,
I'm back with another backlight issue that I thought was simple, but it turned out to be more complex than expected.
Let me provide a brief history: The TV was working well, then one day, the backlight started and shut down. I thought I had an LED issue leading to this behavior, so I replaced the LEDs with brand new ones. However, the issue remains the same.
Next, I replaced the electrolytic capacitors attached to the LED power supply, but the results were the same. I then replaced the driver, a OB3365RP, and did it twice due to the same result.... -
Hello, got an iPad Pro A2378 12.9 5th gen with no backlight. Got another test unit without screen, tested the screen, still no backlight with the test unit.
Figured out the backlight on the screen was bad, ordred a new backlight from mobilesentrix, *carefully replaced it* without damaging the lcd, oh well.
Final result, issue is still there, the screen has no back lights. So i'm back to square one, with 3 hours less and 100$ out, issue still on the screen.
The panel is still ok, i can see the apple in the middle of the screen when it kicks in, just no backlight.
Anyone... -
Hello team,
I'm back with another topic.
It's a 65C715 TCL tv with backlight issue.
But the problem is a bit strange.
When I took this tv from the marketplace backlight didn't work but picture was ok.
Back at home I checked with led tester if led are alive and I can find something different in term of voltage supply => nothing
Putting all back together the tv worked fine for weeks. => Contact issue??
Few moment later the tv has started to have backlight issue back, turning off and on worked sometimes and tv was working.... -
Back Story
I just recently purchased a RZ09-01652 Razer Blade 14 Touch v4(2016) as a project. I suspect the original motherboard had overheated and caused board damage to the vrm's for the CPU and GPU as now that motherboard works however will lockup on you often due to hardware clock issues.
So after some research and looking at options for replacement motherboards I got a replacement RZ09-01952 razer blade 14 motherboard which has the 1060 vs the 970m that was in my original motherboard. I have contacted the seller about the motherboard being bad however I doubt they will be... -
Hello All!
So here is the issue I am having. When everything is plugged in as normal, the TV turns on and I get a quick flash of the backlight. After that the backlight never turns back on but the rest of the TV works fine. If I pull the PWM pin from the cable between the main board and power board the backlight turns on and the tv works "normally". If it is plugged in I get nothing. I did do a factory reset but that didn't solve my issue. When everything is plugged in normally I get .6v at start up and continues rise over about 10 seconds. (~.6v then ~.8v then ~1.8v...
