Hi guys,
I have a Gigabyte GTX 1080 G1 Gaming 8GB gpu. The earlier life of this gpu is unknown.
Fans are spinning on full speed.
All main voltages presents but gpu not detected by motherboard.
The voltage on pin 1 of the bios is constantly 1.8V
During visual inspection i noticed a brown spot on the top of the chip.
Maybe burned this GPU?
Does anyone have an idea where I should go next?
How do I check if the GPU is still alive?

Hy guys, i have this Audi smart key with a touch screen not working, the key has a 450 mA battery inside that looks ok on the multimeter, but when connecting the usb c on the board there is no power consumption, no current going to the board.

Greetings, everyone!
Would need some help with this mini PC, the issue is - after turning on, PC starts, but there is no picture on the screen, no reaction on LED in external keyboard. Tested with another known good RAM. All voltages are present. Looks like BIOS issue to me, right? I tried binary from this site --> [URL]https://www.gigabyte.com/Mini-PcBarebone/GB-BXBT-1900-rev-10/support#support-dl-bios[/URL] ( version F9 ), but still same behavior. Note, I flashed only BIN file from that archive. Although, it says "1.0" in the linked site, but I have board with 1.1 revision....05-17-2024, 10:17 PM -

Hi,
I have an HP 255 G8 that runs for as long as its battery holds charge but won't accept AC power.
I have partially diagnosed the problem and the issue seems to be that there is no ACDRV output from the BQ24735 to turn on the two input MOSFETs. The 24735 has a VCC of 19.57 V, the ACDET input is at 2.93 V and the REGN 6V LDO is outputting 5.98 V, so everything looks good - but ACDRV is stuck at 28 mV.
I've already replaced the 24735 and both input MOSFETs and nothing has changed.
I'd appreciate some suiggestions as to what to try next.Yesterday, 08:45 AM -

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