I believe Chip 2 is BIN is the main one as it contained the Windows product key, marked with XXXXX for now.
SN: PF3G1REP
MODEL: 20KW-00J1AU
PROBLEM: Turns on blank screen, charging circuitry motherboard looks good. I have tried another firmware here - but resulted in 5V will not go to 20v due to different PD firmware I believe - using the current firmware it does go to 20V.
Requesting a firmware clean/BIOS region cleaned. Here is output from ME Analyzer:

You have a laptop that does not power on, powers on but shows no image, crashes, etc… You want to fix it but you don't know where to start.

Sorry, but if you're in situation number 1, we recommend you to use the services of a trustworthy professional repair shop.
Unfortunately, if you're not serious about learning, you will waste your time and money, and you will make us waste our time as well.
If you are in situation number 2, then please continue and... -
I have a 5V 55A led Delta power supply with no output. I found this 7 pin IC 901 damaged as in the photo. All other elements look ok. I checked and every other surrounding componets diodes, resistors and capacitors look ok. I have 2 identical power supplies removed from a led wall which have the same defect with this ic burned but not a working one for reference. I founded by measurements that pin 7 goes to positive hot 450V 220uF electrolytic capacitor primary side. Pin 1, 2, 3, 4 connected together to pcb cooper trace. These four pins goes to negative side of 10uF 50V electrolytic capacitor... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi,
I have a Fujitsu Lifebook E547 vPro that does not boot anymore after Windows Update tried to install a new Bios version. Screen stays black no post - only the numblock light blinks.
What I've tried:
I have used my CH341A to read the bios chip (25Q128FVSQ) (Dump attached) - I think the dump is "good" because I could find the Serial number in the data and also the Winkeyfinder found a windows key.
for the lack of any other Idea I took the bios from this post (https://www.badcaps.net/forum/troubl.../troubleshooti...
