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, I am asking for a little troubleshooting advice.
The laptop seems to boot up fine. Caps lock is working, the touch pad has haptic feedback, and even the "charger plugged"-sound is present.
Power consumption is about 15-30W at boot and idles at about 20W.
Unfortunately, the display and the touch bar are completely black (No signal and no backlight).
I don't get a signal on an external USB-C display either. Also not in safe mode.
I noticed that only the left fan (from the bottom side, hinge on top) seems to spin up. I think... -

Hello, I am looking for any and all files related to the mainboard for 820-2565-A (13" Macbook Pro A1278 mid 2012) schematics/board view.
I looked through forum search results and google and was unable to find a board view file, I found a pdf of all the schematics but I don't know where the parts physically are on the board as this is my first macbook board level repair attempt.
The macbook charger has a green light, the battery has been replaced and OS reports Normal status but Not charging. After cleaning a corroded capacitor it crumbled off the board. There... -
Good day all,
I got a 2007 MacBook from a friend. The fan was not working so it was overheating.
Once the fan was swapped, I installed an OS and it worked fine.
The board had quite a few corroded spots so I removed it, touched those spots with a soldering iron, washed the board in PCB cleaning fluid (I've done that many times), rinsed it with distilled water, dried it etc.
Unfortunately it doesn't work anymore. It does turn on, fan spins, power LED turns on. But no picture.
If I see that right, I have missed VCORE on L7100 (page 59)....
