I have fixed the GPU fan on my Ti4400 AGP by using sewing machine oil and white lithium grease, however, the fan died yet again and the fan connector totally ripped off on the fan itself.

You can use a case fan on the heatsink temporarily, however, the size of those things will prevent another add-on card from being installed, which can be problematic and using the regular fan is the way to go these days.

My recommendation is sewing machine oil and white lithium grease in the bearing shaft area (center of the fan underneath).

How is the phone wired into that? 🤣

How else is he supposed to dial into a BBS?

Ah man I wish I was around for the days of phreaking phones and stuff. I remember watching a BBS documentary where people they interviewed mentioned using 2600hz dial tones to get free internet.
Then they'd dial into a sketchy bbs to grab a copy of the anarchists cookbook.

Todays retro activity case mod like its Y2k ! Lan party grab handles, blow hole with obnoxious case fans, cold cathode lighting, led temp displays, fan toggle switches and custom paint job. Pc case was in really bad shape! I wouldn't cause any harm to a clean beige tower. I'll post some pics when its done. still have to make harness for the fans and some cable management to do 🤣

Changed the display panel of my Libretto 100CT.
The panel for this 100CT is Sharp LQ71Y03

Would you please share where you got a replacement panel from? I've a 100CT with flickering vertical lines on the left side, a common spot, I could clamp it all down and hope for better but a replacement panel would be rather good.

I bought the panel from a Chinese online store called "abctay.com". Paid 50$ (+shipping, taxes, customs..) so not cheap, but I was unable to find these from European sellers or locally.

It was bit of a gamble to buy from some random shop, but the panel is working and seems to be new old stock. I was searching for the lowest price for LQ71Y03 that I could find. There are also several sellers in AliExpress that also have this panel for sale.

Received my Sharp LQ71Y03 for my Libretto 100CT (110CT actually just realised) from abctay.com; jury is out - it was not NOS, it has no lines on the screen, but the contrast is too high giving the panel a washed out appearance and very fine "scanlines" up close. Windows looks OK but DOS games appear very pale. I quickly switched the old LCD back in, contrast good, LCD backlighting not as consistent as the replacement panel. There aren't any interchangeable parts on the LCDs, and the Toshiba DOS utility to adjust brightness doesn't improve contrast.

So jury is out; I appreciate they can't test their LCDs and they've been sitting on a shelf. I'll keep playing around with things to see if I can adjust contrast, gamma another way. They posted it quickly and even called me in Australia to double check my address which is a first.

Doing some testing with the MediaVision AudioPort sound cards.

They work in WFW 3.11 using the Control Panel > Drivers> Add > Other > C:\AUDP method and they work in the OS itself, however, DOS isn't recognizing it and the INSTALL.EXE file says the Multimedia Extensions are required to run first.

I imported two parted LCDs from the UK for a very obscure laptop I've been trying to refurbish for years. Just my luck that each of them had a single dead pixel on them. Finding a good replacement part can be both tedious and expensive.

I had one of these laptops in my youth but had given it to a relative whose house flooded and it was destroyed. Terribly luck. 🙁

There are Windows 3.x versions on the internet that include Multimedia Extensions. Maybe it's worth trying?

Thanks - the panel I received here is definitely off, like it was a "warranty return" panel years ago and sat on a shelf. Let's see if the seller understands/is willing to replace or renew.

Here is another related horror.

I bought a screen once that was otherwise in good condition but the seller didn't take care to place the inverter connector behind the panel. Either in storage or in shipping, the connector had scraped and scratched against the surface of the screen and damaged it severely.

Welp, following my post about that AIW Radeon 9000.

Found it. Resoldered the joints on some suspect caps, made sure there are no bridges.

This is what I get.

I assume that it worked at some point? Besides capacitors, the most common point of failure I've seen is a broken or cracked SMD component on the rear. The second most common is a weakened solder joint due to a defect or thermal stress. Both of these are best found with a microscope.

Worst case it could be a cracked solder ball under the GPU.

The fact that there is video at all is very promising. It doesn't strike me as an issue with the memory, despite the impressive output.

Could very well be the GPU chipset that's dud.

Oh well, time to crank out my old heatgun and some solder paste and see if I can get it working.
I still think there's bad RAM BGA though, or at least the chips' leveling look sketchy to me.

Well, it's an automotive heatgun 🤣, of course it sounds a bit terrifying.

Though, it managed to bring a HP Pavilion DV6700 back to life and it's been running for 4 years without a crash already, so I guess that's something. Intel + Geforce 8400M GS though, not the AMD counterpart.

All of the GeForce 8 series mobile GPUs have a manufacturing defect that caused early failures. The exact cause I think was unclear but there was a class action lawsuit and a moratorium by manufacturers for years on NVIDIA mobile GPUs.

I had the opinion that this was early in the ROHS transition and the formula used in the solder balls or flux was defective. That's just my opinion though.

Honestly, getting 4+ years out of it after a reflow and considering it's still kicking alive, that's really impressive.
At this point, if it's still gonna hold this good after so much time, it's a miracle.

Back onto the 9000 - I haven't yet tried reflowing (it's Christmas) as I'm going to work on another project but I'll keep in mind to first try and reflow the GPU, and if anything fails, aim for the BGA SGRAM.
