Hi there,
First, I'm not sure it's the right section to post for this type of device, but could not think of something better.
Ok, so my son (a mechanic) bought a faulty Hofmann Geodyna 6300 wheel balancer (which appears to be mostly a re-branded Snap-on wheel balancer).
I'm looking for any resources (doc, manuals, schematics) that would be available for this device or anyone that would have any knowledge on this particular device (or its Snap-On equivalent).
I'm trying to diagnose the fault(s ?), but I can't find any schematic (appart from the... -
Good day!
I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.
Here are the voltage readings:- Input – 19V (stable)
- +LCDVDD – 3.3V briefly, then drops to 0V
- EDP_HPD – 3.3V briefly, then drops to 0V
- PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
- EC BKOFF# – 1.8V briefly, then drops to 0V
- PANEL_OD_EN – 0.3V
Is it possible that the EC chip is corrupted or damag... -
Hello, I'm stuck in troubleshooting…
The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.
In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
When I press the flash button, it's detected by the system, flash icon appear on LDC display.... -
Hi everyone,
I have a MacBook Pro A1989 that was likely exposed to liquid. It doesn't display an image on the built-in screen, but the screen is backlit (you can't see the Apple logo or any other elements when held up to light). The laptop provides 20V and 1.5-2A, and it works fine when I use it with an external monitor. Currently, the connector for the display (J8500) is disconnected. I'm writing to ask for help in diagnosing the issue. I've heard that when the J8500 is exposed to liquid, the processor pin responsible for the display might short-circuit, and I'd like to know... -
Hello!
Looks like I fried something when my EDP cable got squeezed on the hinge. I replaced the cable but still no display. Laptop works fine with external monitor connected through HDMI and Display Port-USB C port. I took it apart and I see a burnt component. Can anyone help me identify what this component is? I tried to use schematics for another G15 but it does not match on the amount of pins and size. I attached pictures. The component has a label on it - (21A29)
