Acer predator XB241YU Component identification

by Shulgin

Hello everyone,
I have a problem with my Acer predator XB241YU screen. When I plug it in, the startup LED turns on instantly, and I can't turn off the screen without unplugging it.
After disassembly and inspection of the electronic cards I found what looks like a broken inductor, it is marked with the letter A and is at location L58.
In the first photo you can see the broken component, in the second photo you can see where it is on the board, in the third photo you can see the silkscreen and in the fourth photo you can see the identification sticker of the main board

BOSCH Microwave CFA634 error E1006

by AlexVG

Hi,
I have Microwave BOSCH CFA634
It runs, but after 10 -15 seconds stops working.
Sometimes it shows error E1006.
I can't find this error explication.
Some people say it's communications error between main and display module.
Probably somebody has an experience with this issue?
Can you help me please?
Thank you an advance....

Quecoo T12-958 soldering station - INVER error?

by spleenharvester

I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.

Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.

Any idea what the problem is?

A1706 short PP3V3_S5

by madjid911

Hi friends,

I have a macbook pro A1706 820-00923-A that won't start no signs of life, no liquid, checking the voltages I found PP3V3_S5 was shorted, I removed all the processor coils, but when I 'injects a voltage it is the processor which reacts, can you confirm to me that this is definitely coming from there please?

I have 20V on the usb-c connector, and 13v stable on ppbus_g3h.
I saw that a track had burned out on PPVIN_2V7NAND_LB after resistor R9350
I injected voltage on L7660 pin 1 in short but only the processor reacts

Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

A1708 820-00840 20v 0a

by sewsulle

Good Afternoon,
This is my first post here so I apologize if I miss something.

I'm working on an A1708 that draws 20v and 0a with the board removed.
When installed in the machine, it takes 20v and 0.1a. The fan spins up and the trackpad clicks.

Some measurements:
PPBUS_G3H: 13.13v
PP3V3_S5: 3.3v
PP5V_S4: 5.1v
PP3V3_S0: 0.6v

Any help would be appreciated. Let me know if more measurements would help.
Thanks in advance
