Re: Acer C733-C37P Chromebook
It's the USB-C port above that's used for charging, so I would think any potential issues would be up there.

Acer C733-C37P Chromebook
I have a stack of about 15 of these Chromebooks. All of them failed in the same way. First the primary USB port stops charging, then the second USB port stops.
The Chromebook works fine when a fully charged battery in installed, but the charging circuit is bad. Really cheap, crappy chargers come with these Chromebooks. So something is zorking the USB ports when the laptops are plugged or unplugged by students.
I've attempted contact Acer many, may times about the issue, but they refuse to respond at all. Not so much as a peep. Horrible customer service.

Re: ViewSonic V2000s display issues
Well, this turned out to be a long project, mostly because of work... which is a good thing in this economy.
I replaced as many caps as as I could, plus I went ahead and replaced the crystal oscillator. Cost me about $4 in parts at my local surplus electronics store.
So far so good, and the picture looks clear. With my horrendous soldering skills, I'm just happy it turned back on and has a picture.
I bought a little bit of solder paste, and that stuff has been unbelievably helpful. My hands shake pretty bad, so trying...

Re: ViewSonic V2000s display issues
No pictures yet, I dont have a camera. But I took the board out and it had some brown residue along the edges causing a little bit of rust. I'm going to use a soft toothbrush to try and clean it, then let it dry.
It looks like one of the small surface mount canisters may have leaked.
The other thing that worries me is that it rattles. I haven't figured out where, but I think it coming from one of the capacitors. It's weird.
I'm absolutely horrible at soldering and I could never do surface mount if my...Leave a comment:

ViewSonic V2000s display issues
Howdy, got a referral from MacNN.
I got a ViewSonic V2000s for $10 at a computer recycler, plus $30 for a stand. It works 90% of the time just fine, but every now and then it looks like it's stuck in 256 colors regardless of the color depth. It flickers a little bit, too, when it's doing that. I've tested it on different computers when it's doing that, so I know it's the monitor.
Any ideas? I may crack it open and fiddle with it, but I'd like to know where to start.
Smacking it doesn't seem to change anything, so I don't think it's a loose connecti...
