HP PROBOOK 650 G1 BIOS
Hello,
I have an HP ProBook 650 G1. I lost the original BIOS dump, so I flashed a BIOS file taken from another device of the same model. However, the laptop is now slow to boot, and displays a red warning message before startup.
I've attached the BIOS file I'm currently using. Any help to restore the correct or cleaned BIOS would be appreciated.

Nvidia Quadro P2200
I’m troubleshooting an NVIDIA Quadro P2200 graphics card that isn’t recognized by Windows. I’ve discovered a missing SMD probably 180 Ω 0402 resistor on the opposite side of the PCB from the GDDR5 memory chip labeled M1.
To proceed with the repair, I’m looking for a schematic or boardview file for this card — or any other confirmation regarding proper spare parts needed.
If anyone has access to service documentation, layouts, or high-res boardview screenshots, I'd be grateful for any shared resources.... -

HP OMEN MAX 16-ah0006nf bios
Hi,
Can you clean this bios with a new image or clean the intel region please ?
Because the laptop starts but no display, the shift key flashes 5 times long 3 times short, this indicates a corrupted bios according to my research, I did not find a bios like this model, so I attach the original one.

Hisense 65R6E3 double-image / horizontal strips - TCON?
Hello all. 3 years back, with your help, I replaced the LEDs on this TV. It's been working great. Yesterday, I turned it on (garage TV), and it has blurred horiz / vert lines as you see in photos. Definitely no physical hit or damage. Top 1/6th of the screen is perfect. Could it be main / TCON board? No tabs to cut on this model. Thank you...

Tx-pr42gt30 6 blink
👋🏻I recently got a tx-pr42gt30, I bought it in non-working condition. When I opened it, I saw that all the transistors and diodes had been removed from the tnpa5330, and several microcircuits were in poor condition, so I decided not to try to repair it. Instead, I bought another tnpa 5330 (also AB), which was already repaired (according to the seller, the board was repaired and worked before the screen was damaged), transistors were also changed on it, but Chinese copies were installed (there is no round hole in the middle, the inscription is easily erased) and a pair of transistors that... -
