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.

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about... -
Hi
Picked up another TV. Samsung UN43NU6950FXZA. No power and no standBy led on. Removed back cover and:
Main fuse = OK
Back light LED = OK. Power them with aux power source
LED output = OK 156V
I do get 12 V DC out of the power supply going to the digital section but no 5V or 3.3V. PS_on voltage is only 1.8V. I have looked everywhere on the PCB , I could not find i reference for 5V output.
Also removed connections to panel, speakers and remote but no luck. One strange thing is that even with the LED power supply working, backlight LED do not turn on...07-20-2025, 08:06 PM -
Samsung UE75MU7009TXZG Endless Power Cycle
Hi everyone and thanks in advance for any help I might get here
My Samsung TV is about 4 years old. The exact model number is UE75MU7009TXZG.
About half a year ago I started seeing occasional green frames pop up while watching movies. I mean literally green frames. Not the image turning green, but the entire screen turning green for a split second. This happened maybe once or twice during a 2 hour movie. So no big deal, but clearly something was not quite right.
Since a few days, the TV won't turn... -
Hi All,
First time posting here ... my name is Kevin but my friends call me Journey.
I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again....
