Toshiba 50L420U/49L310U TV, press power button, it shows Toshiba Logo then backlight off.
Tested the backlight stripes with backlight tester, all 3 sections seem to be good.
The problem is the power supply PK101W1100I , 2 backlight feedback resistors open in my case, the value mark 101, they are both 100 Ohm.
I replaced the 2 resistors with same value fixed the problem.... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hello, I have an "ASUS ROG Strix G713QR" laptop, and for approx. 3 months I have the following problems:
1. Laptop keyboard doesn't work
2. The backlight on the laptop keyboard doesn't work
3. The x2 side LEDs (red) on the laptop don't work
The power button works, the touchpad works, and all the USB, HDMI, Ethernet, etc. ports work.
I already tried to reinstall all the drivers and reinstall Windows. So I don't know what to try anymore that is software-related.
But I am strongly aiming that it is somehow a BIOS-related problem,... -
I have a Panasonic LED TV TC-40A420U. The TV was given to me as an attempt to fix or throw out. I replaced the Backlight LEDs and now the screen lights up, but there is no image/display. If I play with the up/down buttons I can get the display to change from black to garbled. I can't get sound from HDMI but not sure of what input is selected. I have no remote control. When I connect a laptop to the HDMI ports it recognizes a Panasonic TV for display and sound output but I can't see or hear anything through the TV. This makes me think the mainboard is OK, but not sure if mainboard can...
