Hello everyone,
Inside the console there is a small circuit board (see photo) that contains the main power switch, the one on the front.
This circuit board connects to a 10-pin flat cable called NEXUS that terminates on the motherboard.
This NEXUS connector broke.
Can anyone tell me, while waiting for a replacement, if it's possible to turn on the Xbox by disconnecting this circuit board and making some modifications (like adding a small power button) on the motherboard?
The Xbox has a power supply that provides 12 volts on all outputs, so the power... -
Hello.
I have jut got my first analogue oscilloscope. An Isotech 620 20MHz.
I want to learn how not to damage it, and I found instructions on the internet obscure.
They talk about ground, earth, floating ground, this, that....
But they don't actually say anything anything useful so far.
I want to know:
Don't connect exactly this to exactly there or it blows up.
For example, I am tracing a signal from a function generator in an audio amp, or testing for voltages in different parts of a circuit.
I want to know what not to connect... -
I did an hdmi port repair for a PS5 and I lost the small diode z71 SOD923 on the back of the port. I did a trace repair for pin 19 of the port as well. Without the diode I get no display at all. I tried replacing the diode twice but after I get flux on it the marking comes off so I can't tell if I have it on the right orientation. When I measure I get a reading of 1(open) and 923 in diode mode. Is 923 a normal reading for these and also which side should the reading be with regards to the arrow on the board?... -
Hi there!
My friend wants me to help him repair his old-real-vintage strong-hammer machine. Well it's only 90% real as the force applied doesn't lift the weight itself but it is measured and it moves a motor that lifts the weight
I am attaching several pictures of the machine.
It basically has 2 sides, left side has- 2 x 220->12+24v transformers
- 2 relays (1 moves motor UP, other moves motor DOWN)
- IGF and breakers for safety
- Logic board. Receives 24AC and recitifies it into DC. Contains a uC (M80C85)

Hello,
I have a CFI-1215A PS5 (EDM-030 board) here that won't boot normally. It currently will immediately boot into Safe Mode upon power button press with a screen that says "Processing" and then a progress bar that usually begins around 75-84% and slowly climbs up to 99% where it will hang forever. The console will not ever escape past the 99% mark.
Things I have tried:
1. Tried force booting into Safe Mode by pressing and holding power button for 2 beeps so I could use a reinstallation USB, but the console still boots into Safe Mode with the...
