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... -
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,
I'm a beginner at laptop repair. I bought a MacBook Air A2681 that doesn’t turn on, just for practice. PPBUS_AON and the other always-on voltages are present and look fine. I did some diode mode measurements and got unusual readings (compared to reference values I found online) on LC320 (44mV) and L82D0 (40mV). LC320 corresponds to the PP5V_S2 power rail, and L82D0 to PP1V25_S2.
I injected 1V (current limited to 100mA, the board consumed around 86mA) into PP1V25_S2 to see if anything would heat up, but everything seemed normal. I did the same with 5V (current limited...
