Hi guys, I need help from expert people (I try to repair at an amateur level I'm not a technician), I have this asus AIO ET2012E computer with a missing backlight problem, on the backlight cable in the central pins I measure 19V while from as I understood 45V should come out, the diode looks good as well as the resistors and capacitors, could it be a problem with the MP3394 chip? Anyone have suggestions? Thanks, I'll leave the schematic here

by CornitoHello 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.... -

I have a computer all in one Asus ET2012E v2.00 with a display issue. When I put it ON, power LED goes ON, cooling ventilator runs but not nothing on the screen. I had connected to external sceen by HDMI but nothing again.
I'm look for motherboard shematics . Any technical information will be helpful
Thanks you again!

by cheebsterHello, 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.

by MaineFixHello Everyone,
Today I'm coming to you regarding my issue which is no Backlight .
I have image on my screen but no light.
The Laptop was one that came into my shop. Originally it came into the shop with an HDMI port issue. We replaced the mobo and now have a backlight issue. I took off the LCD display and removed the ribbon cable and peeled back the adhesive covering over the board that is connected to the LCD to identify any issues. I took tweezers and wiggled every connection. Everything appears to be fine.
Looking for advice.... -
by CornitoHello 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.... - Loading...
