Re: Viewsonic VA1912W's No Blue

So just to recap (pun intended!), I was able to fix five out of six monitors and all are working great. The sixth one did start up after the initial recapping, but then it made a snap noise and the backlights and video went out. I've checked the fuse (good) but there is simply no power output from the power board to the video board or to the backlight inverter. I suspect the transformer itself went but at this point I don't really care. Saving 5 out of 6 from the trash heap is pretty good. I'll hold onto the LCD screen itself (which still works fine)...

Re: Viewsonic VA1912W's No Blue [solved]

DOH! and LOL. The laptop's video port was the culprit! I used a different laptop and the monitor is working fine.

I've since recapped my third monitor and it's also working great. Three more to go. Thanks guys!

Re: Green Screen of Death on Compaq nx9010?

With laptops, it's often very important to install the manufacturer drivers for chipsets, video, audio etc, first before updating them to a generic one. Often times they will have some proprietary hooks in those drivers for manufacturer specific functions (like volume buttons and the like). For example, many dell laptops (and even some desktops) need the dell intel chipset drivers installed or certain audio cards will simply not work.

Re: Viewsonic VA1912W's No Blue

Thanks for the replies guys.

Yea, the OSD is in full color, but there is no blue color available. I get a windows desktop but it's just greens and reds. I did use the same laptop and video cable for both tests and you make a good point. I'll try the setup on a known working monitor tomorrow. Perhaps the problem is with the laptop and/or vga cable.

ben7, I'm not sure I'd know how to do this. Is it shorting certain pins while powered on? using the OSD menu to reset defaults? Any elaboration would be helpful!

Re: Green Screen of Death on Compaq nx9010?

While in the BIOS look for an integrated devices section then network or NIC, see if it allows you to turn off PXE on the NIC/Network card. Otherwise, as radio fox stated, disable or move network boot from the boot menu.

Hey all, long time lurker, first time post. I've started fixing a batch of Viewsonic LCD Monitors. I found the power board with bulged blown caps (capxon greenies, 2x220uf, 1x2200uf and 1x1000uf) and I'm replacing them with same spec Panasonics.

My problem is, the one is working now, but there is no blue color on the LCD. In the OSD Menu, all colors are set to 50% but adjusting them does nothing. This is the second one I recapped, the first I think also has a blown inverter chip for the ccfl bulbs, the screen stays black on that one (though the power LED no longer flashes on and...

Re: New Members - please post your introductions here

Guess I'll introduce myself as well (joined a few weeks back but never got around to looking through all the other sections until now).
I started off in the early 80's with an Atari 1200xl (buggy computer though). I upgraded to a 130xe and had the memory doubled to 320k (oohhh...ahhhh) for a killer huge ramdisk (for an Atari anyway). I ran the Riverboat BBS (east coast Philadelphia area) off of it with 2 stock 1050 disk drives and 2 modified 1050's that did true double density. Those along with my HUGE ramdisk gave me...

Re: Thinking of doing my first recap

Well, I got the 6 1500 uF caps out of my practice board. It went very smooth and easy. I went and bought a 45watt Radio Shack desolder iron with the vac bulb on it. I wasn't so good with the bulb itself but the iron worked great. 3-4 seconds of heat on each cap leg and they were out and everything looks clean. The practice boards caps all blew out the bottom. I'll solder some new caps in and see if it still boots (it did before I started, just gave lots of memory errors or windows would crash while booting). Anyway, the desolder irons hollow...

Re: Thinking of doing my first recap

Thanks for all the tips. Yea I have an old PIII 433 mobo here that is also flaky...runs but crashes alot, though the caps don't look blown, guess they could still be bad. Anyway, it's not worth saving so would make a great practice board. I'll definitely play around on that one first. Again, thanks for the encouragement. I guess I'll plan on ordering up a bunch of new caps and give this a go.

Hey everyone. I guess like everyone else I ended up here after finding blown caps on a computer and figured they can be replaced. I was actually hoping I could find someone local to the Philadelphia area to do it for me. I've done some minor soldering before, but never a multi-layer pcb. Anyway, I've read all of the faqs and other posts but I guess I just need some confirmation before I begin. I have an older IBM P4 Desktop (1.8ghz) that I bought for 99 bucks for a friend that just needs a cheap computer (to replace their still functioning P166 Packard Bell on Win95). I can return this one and...
