Got a Kenmore Kenmore 790.74133311gas range with a control board 316630005 which has a blown PWM. Anybody has an idea what that chip is?

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
Hi all, I just want to share the repair of my 60PK550-UA TV set.
The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.
But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.
All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
C57: 3.30V

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

I am looking at the option of replacing my control/driver board to one with HDMI and/or Display port input on a 2K LED (I think IPS) screen.
The display is Samsung LTM270DL07.
I have tried using the model number to search for a compatible control/driver board but so far my efforts have been futile.
I am looking for inputs on what board could potentially be used for my display.
Attached are pictures of the display label information and connectors (CON30 CON40 only) and pictures of the current control board.
Also attached is a technical...03-14-2023, 08:52 PM -
Hi guys!
Firstly, I will apologize if my topic is in the wrong section, please move it if necessary.
I want to repair one treadmill from the brand Horizon the model is Omega II. Practically, the motor power control board has suffered one damage.One mosfet has blown and I suppose by doing that, the short circuit has damaged a couple of diodes, one zener diode and two transistors. I hope that is all. I will find out when I will put them all back on board. I have dismantled and cleaned the rotor of the DC motor, tested it, and it seems to be working properly. I suppose it was water...
