Hello all, I looking for schematic or boardview for Hp probook 640 G8 dax8qmb28a0. The laptop after water damage and have some missing components
-
I have a brand new 13.6-inch MacBook Air M4 that was only used for three days and now has water damage. A glass of water was spilled over it. I examined the motherboard and there was only water next to the display connector. I cleaned it with isopropanol and the components look clean. The MacBook obviously turns on and draws 20 volts from the power supply. The keyboard backlight comes on, but the display remains black. Where should I best start? Even when I shine a light on the display, I don't see any image. I have all the tools I need, including an infrared camera. Where should I best start?... -
Hi! My friend just brought this audio amplifier/speaker fro his music band saying they realized its got no sound. Led powers up but there no sound at all
I opened it and found 3 board. 2 of them are for input plugs and potentiometers, and the other larger board has the amplifiers for 2 large speakers that it drives
There's also a large toroid transformer that feeds a lower voltage to the first 2 boards and a larger voltaje (36x2 rectified close to 100v) to the power board. The power board has the plugs for both speakers
There is only one signal wire connecting the first boards... -
Board: DA0X9QMB8E0
Board was water damaged un 3 resistors are dead.
Does anyone know the values of the resistors? (see photo)... -
