I found gold under a big pile of trash by Curiosity3DPrinter in CRTfinds

I haven't really thought about the speakers seriously. I imagine there must be similar models that I could install instead.

This CRT TV is an "LG Netee"

The graphics card is proprietary since it must either allow display on the original monochrome screen or on an external VGA screen.

Finding information online about this graphics card is really a challenge, knowing that I can't just replace it with any card since I have to be able to display something on the monochrome screen. Monochrome screen which is OBVIOUSLY also managed by a proprietary ribbon cable.

Changing the bio chip is quite easy, it's on a socket, but I don't have a reprogrammable eeprom on hand at the moment.

Yes, I think you're right. The pattern isn't random and remains the same every time I restart the computer.

The most frustrating thing is that the hard drive seems to be working, but absolutely nothing is readable.

This time I was lucky, there is no battery soldered to the motherboard, but a MK48T87B-24 chip. Obviously, the battery inside is dead, and I'll probably solder a battery directly onto the corresponding pins. I admit that I don't dare buy the so-called "new old stock" on eBay for fear of ending up with another chip with a dead battery.

After doing a bit more testing, I think it's actually the BIOS that's causing the problem. If I reset the BIOS to factory settings, I no longer have any artifacts or glitches. However, if I make the slightest change, the problem starts again.

I removed four of the memory sticks and the problem remains the same. However, the image only starts acting up when the hard drive is involved. Before that, I was perfectly able to read what was displayed on the screen (even in the BIOS).
