Hi,
i had a HP 640 G8 with a DA0X8AMB8E0 Board. I would Flash the BIOS, but i used a CH341A Programmer with 5V instead auf 3,3. Then I thought the BIOS was now defective. I have already replaced it with a new one (flashed the same BIOS).
With the new chip, the notebook has the same error. The charging port lights up once and then goes out again. The notebook does nothing more.
I iced the board with a cooling spray to possibly find a chip that gets hot or has a short circuit. Unfortunately, I didn't find any. I suspect a fuse might have blown. Does anyone...Yesterday, 02:47 AM -
I have a nacon controller which has some fancy RGB ring (4 RGB LEDs). 3 of 4 leds are not good and I am looking for a replacement. The size I measured is 3mm x 2.5mm and it seems a 3528 led would fit fine, and it's in common anode. But I am not sure what wattage it is. I have attached photos of led and driver ic (ak63rq1 I think).
Also one of the triggers is malfunctioning sometimes, I don't know what these pots are called. I measured across the 1st and last legs (in circuit) seems to be 1.1kohm pot. I found some xbox controllers have this but they are 10k. Any info?...06-05-2024, 08:28 PM -
I found my old Xbox 360 in storage and opened it up to see if there was anything that broke since it was built in 2006 (launch era Xenon revision, never red ringed, never been serviced) and didn't want to find out by releasing magic smoke. Upon moving the dust bunnies out of the way I was greeted by a bunch of capacitors with crud coming out of the top; it doesn't seem to have leaked onto the board so at least I have that going for me.
I'm posting here because I want to try to source replacement caps myself from Mouser or Digikey instead of braving eBay or waiting for places to have...Yesterday, 05:10 PM -
Hello,

Most Displays I have worked with are of course LCD Or Blueish Fluorescent Types. I Have a Marantz PMD800 tuner with sort of a white display. The display area is a sealed rectangular shape in a Glass Case. Looks like some sort L.E.D. display only not your typical section number type. I picked up this Tuner cheap as the display is very Dim. In front of the circuit is a dull red Plastic lens.
The display is very week and hard to see. I've got my DC 5 Volts allover and also a DC 32 Volt that runs some other section. Power supply looks good front to back. Not familiar with this type...Yesterday, 07:19 PM -

I have this 1707 with the 5V 0A power loop issue on 3 of the jacks.
One of the CD3215C00 had corrosion under one side U3100 to be precise.
This USB jack was drawing ~.2A and not boot looping.
After replacing the CD3215 I am having an odd problem. I can rotate the USB-C and it only works in one orientation. And now it boot cycles, like the other usb channels so I'm part way there.
After looking at the schematic and board view. It makes very little sense that this is happening since they both pin 59 and pin 60 both go to the same places on J3300.

Hi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.
