EVGA Nu Audio Sound Card - Not Working

I have an EVGA Nu Audio sound card that is not working properly and I need some help diagnosing the fault (preferably by someone who owns this card and is willing to take some measurements).

The card sort of powers up (LED lights are coming on and the relais is clicking, some voltages are present) but it is not detected in Windows. I tried installing in two different PCs and tried several driver versions but the card was never detected anyway. So I thought this is probably not a driver / software-issue and then disassembled the card to take some measurements.

I found...

It could be a lot of other things too. Is your bios on the latest version? What operating system are you on? Sometimes the "fast startup" option in Windows 10 can cause such problems. There could also be a device (network adapter or USB device) that is allowed to wake the computer....

Could be a faulty power button.

Same situation here. DRAMRST# not present. I don´t know where to go from here. I made made some pictures where all my findings so far are marked. Maybe someone can explain what to check next.

The cap side you labeled 0V in red is the ground side. If there is a connection from there to the coil you may have a short somewhere downstream.

Well, I might have been a little to enthusiastic about this one. The fault came back after one day. It worked fine initially, I did a fresh windows install with multiple reboots and everything was flawless. And then the next morning I get the same 2 yellow 3 white flashes and the device doesn´t boot anymore. This is driving me nuts...

I eventually revived the machine. For reference, this had the 2 yellow and 3 white LED flashes which is described by Dell as "RAM not detected". The solution was to flash the following bios kindly uploaded by user "hardware1":

Many thanks to Hardware1 and the clean bios he uploaded in post #45. It worked fine in an Inspiron 3793 and eventually revived the machine. For reference, I had the 2 yellow and 3 white LED flashes, which is described by Dell as "RAM not detected". Flashing the bios has solved the problem and the device is working fine now.

Panasonic AG-1000B VHS player with bad picture quality

Hello!

I recently got an old VHS player from Panasonic and just for fun I want to try to repair this device. It is an AG-1000B portable VHS player from 1990 and it has a problem with picture quality in playback mode.

Picture in playback mode is very noisy and often loses sync but the still images are nearly perfect.

I want to know, is this something that could be solved by recapping or is the video head likely gone?

Also, what mechanism is this?

Any feedback is appreciated!...

There is a BIOS with onboard RAM disabled in this post:

Is that a burned spot on the board just below the BQ chip?

Thanks! Board is still not working, it probably has other problems. When I plug in the power adapter it idles at 0.015A and briefly jumps to 0.200A when pressing the power button but it goes down again immediately. Keeping the power button pressed heats up an IC which is likely the 3.3V LDO. Should I replace the IC or does it indicate a problem with the EC or PCH?

Can someone please take a look at this bios? The board does not power on at all but voltages are present (19V/5V/3.3V/1.8V).
I already tried to put together a fresh bios with the existing ME but it did not solve the problem so I guess I must have done it wrong.

The problem was related to the flex cable that is attached to the screen. This cable is prone to get cracks over time from opening and closing the lid. Unfortunately the only option is to replace the whole display assembly. Look on Lenovos forums, this was a problem for many owners of this model....

Make a backup of your current BIOS before doing anything (can be done with GPU-Z).

Flashing a new BIOS can be done with Nvidia NVFlash or with a USB programmer.

Latest rom for your card is here: [url]https://www.techpowerup.com/vgabios/219116/msi-rtx2080ti-11264-200203[/url]

Besides all the VBIOS stuff, check your display cable as well (just in case it´s that simple...)https://Make a backup of your curren...SB programmer.
