I was watching a YT episode from Nick's TV Repair and he literally had a test jig comprised of all the internal components of a TV on a wooden board.
I thought that was amazingly smart as I always thought that TV repair businesses had a room of various actual TVs they would use to do testing.
My question is how was he able to connect this generic looking external display to the jig? The connectors are intentionally covered up by cardboards so we cant see it but i wonder if its a custom in-house device or something that could be purchased online?

i got myself a complete Antminer T17+ with 3 dead hasboards for a very good price.... for parts i bought S17PRO boards.... i replaced all missing resistors and changed some asics because they were bad... but wihout a tester... i used the miner instead and changed firmware to awesome miner firmware for better and faster diagnoses via miner log and lower fan speed...
for my understanding and what i read on the internet these asics should be interchangeable in one chain but in my case i´m getting no more communication to none of the asics on all 3 boards. 2 of the boards weren´t in... -
Hi,
please I have this APL6012 circuit on my NB defective - it heats up. I soldered it but the NB still won't start. All voltages are present - except for battery charging.
The NB can be turned on, the keyboard lights up, the current consumption is slightly over 1A. All voltages are present. But nothing happens. It's just that as everything heats up, the current slowly increases.
Should the NB turn on without this circuit or does it need it to start? I don't know if that circuit communicates with the EC.
Thank you very much for your responses.

To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment... -
Hello. I have a faulty Gygabyte Eagle GTX3080 GV-N3080EAGLE OC-10G revision 1.0video card. It was incorrectly inserted into the pci express socket and an integrated from pin 11 was affected. I don't know exactly which WAKE # Link Reactivation or PERST # PCI-Express Reset signal. I found an integrated circuit burned out that I found and replaced but it didn't start. I think it's connected to another integrated circuit near it but I don't know exactly what kind of part this is AL NB 0X 1F. I would like if someone has a schematic diagram of this board or if he knows the piece and what equivalent...
