by Jedi134Hi I have inherited the above desktop scanner, all seems to work correctly but there is no sound output. The only sound I do get from the speaker is the beep confirmation when you press a key. No output from the headphone socket either. Not even radio static with squelch fully turned down, tried a reset by holding 2, 9, and hold buttons but still no sound, does anyone have any experience with these scanners, thanks.

by AlexVGHi,
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....05-17-2024, 05:17 PM -

by ShulginHello 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

by OficinadopcI'm trying to enable this Asus X512DA. This model came without backlit and I ordered a keyboard with backlit. As I've been searching on the internet, It seems that the bios as to be modified at the offset DD to 7E. Since I don't have enough knowledge to the task, is there anyone who can make it for me? I attach the original bios file.
Really appreciate the help...-

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?05-06-2024, 01:36 PM -

by madjid911Hi 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
Thanks for your...Yesterday, 12:33 PM -

by lostoneHello, 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...-

by sewsulleGood 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 advanceToday, 01:29 PM -

I was wondering if you guys know anyone that sells Super IO chip ITE IT8390-256 flashed with your specific laptop. Im debating to see if this available out there vs buying chip and programmer myself. Right now the chip plus programmer is about $60. But i still need the file that goes on chip. The laptop is RAZER BLADE 15 RZ09-0369.Today, 01:22 PM
