Re: eMachines T3092 random no video; bad caps?

I can't believe it. I followed all the advice and instructions on the website and... it's working perfect! I honestly thought I would screw something up and melt the circuits and install the wrong capacitors and the board would never function at all afterward. But no, not only is it working, it's performing better than before in many ways. I didn't realize it would be so much more responsive - after fixing. How is that? I must not have even noticed it had been slowing down over the years. If you ignore that the hard disks are completely...

Re: eMachines T3092 random no video; bad caps?

Wow that's a relief, thanks again for the continued support guys. I wasn't sure what you could identify in the pictures and I didn't even mention the series or other markings. (I figured out the focus issue on my camera btw if any higher-res pics are needed...)

United Chemicon eh? Hmm...

10mm x 20mm.
OK. Can't do anything to the motherboard yet anyway. Currently having trouble *removing* the caps from my practice board (a PCI winmodem, which thanks to my efforts has lost some of its traces); but...

Re: eMachines T3092 random no video; bad caps?

OK, even with magnifying glass this camera sucks. While I try to figure out how to improve the focus, these shots should help you see the placement of all capacitors including the obviously bad ones. (you'll just have to take my word on how they look)
I've identified and labeled all of them as best I could, so hopefully it
should be easy to figure out the missing values (the ratings of the one by the PS2 ports and the fat one near the IDE cable slot) by their location, and what's best to replace them with, if you're so...

Re: eMachines T3092 random no video; bad caps?

:O
Uh oh. I didn't see those reviews. Maybe it's not built for gaming?
How do they build a 500w power supply that puts out <300w?


That's a great idea. I would have never thought about it. I'll post some pictures of the caps in the next post, in case anyone wants to help identify them and what to replace them with. I can read most of the markings and brand names though. It (the computer) has nichicon, rubycon, and teapo among others. Havn't opened the PSU yet. Thanks for the advice....

Re: eMachines T3092 random no video; bad caps?


Yes, I read over that a few times already. Without having money to spare, just getting it replaced will be cheaper. (but then I'd still want the old one fixed eventually) Have also read his Recapping tutorial.
Thanks for the capacitors link. Bookmarked it. Still have to find out what rating they all are.

You think the Bestec one is usable? It seems the consensus here has been that Bestec PSUs are death traps. Is that just the 250w ones?
Might be good to recap it anyway for practice. (but going to...

Re: eMachines T3092 random no video; bad caps?

Nevermind I found it. The failed ones say "2200uF, 6.3v"....

Re: eMachines T3092 random no video; bad caps?

Thanks for all the replies!

Sorry I wasn't specific about the replacements. Actually the eMachines part is a "Replacement Upgrade Kit" which includes:[INDENT][B]ATI RC410 Chipset Motherboard
Intel Pentium-4 2.80GHz Processor & CPU Fan
1GB DDR2 PC-4200 Memory
Power Supply 300 Watt
Software/Driver CD[/B][/INDENT]

They don't sell the exact AU31 MB any more, which accounts for the high price.

Hey there. After a few hours of web searching I found this forum and hope the experts here can give me good advice. I had never heard of "bad caps" before yesterday.

This is on an old eMachines T3092 AMD XP 3000+ w/AU31 motherboard that's worked flawlessly until now. (Well not really, the CPU speed dropped to 1.3MHz a few months ago)
While just surfing the web, the machine clicked and the video cut out. Since the case fans and power were still on, I assumed it was just a problem with the graphics card, and switched to on-board gfx. At that point it would boot up...
