Re: Asus VL279 (VL279HE) - possible short?
No, that can't be it, I tried 3 different known good adapters. I'll try replacing the NIKOS PA410BD TO252 MOSFET....

Asus VL279 (VL279HE) - possible short?
I have an Asus VL279HE, PCB model is 4H.42101.A21
The symptom is that there's no power at all with it with the AC adapter hooked up. The fuse tests ok, but when the AC power adapter is connected, I do not get a voltage reading with my DMM from the pins on the back. The connector itself tests ok, which leads me to conclude that there's some short on the board which is triggering protection in the AC adapter and causing the voltage to go to 0.
I am not certain where to start looking beyond the fuse though.
Thanks... -
MSI K9VGM-V (MS-7523) - How Do I Diagnose Short
I have this motherboard, I replaced the VRM high and low caps as well as a couple 6.bloated 6.3V 1500uF 8mm caps by the memory slots. I purchased the board in this state and I'm pretty sure nothing I did caused the current symptom of it not working.
The particular symptom is that when I apply power, the CPU fan will turn on for the briefest amount of time and then turn off, and then it will not even attempt to power on unless power is completely removed.
So this sounds like a short somewhere, but I was wondering if someone could help me out with the best way to test... -

Ah yes, didn't Brent Spiner (Data from Star Trek) make an appearance in an episode?
Ah, so [i]that's[/i] the T3500... I was thinking of the T3400.
What about those China special X79 2011/1356 boards? They're nowhere near as good as the T3500 which is properly engineered and put together, but they're standard ATX. Wouldn't trust the polymer caps they use on those things though.Re: Intel SDE AVX and SSE4.2 patch

Re: Intel SDE AVX and SSE4.2 patch
Good luck finding a reasonably priced 1156 motherboard.
You're better off buying one of those Chinesium motherboards that take the Xeons with the triple-channel memory support. The boards are like $100 or so and the Sandy Bridge Xeons go for very little... And soon they'll be doing the Haswell version of this if they're not already....Leave a comment:

Re: Intel SDE AVX and SSE4.2 patch
Time to ditch Wolfdale/Harpertown.
I picked up a nice ATX Socket AM3+ board locally for $5 with a bios mis-flash, and then paired it with a bargain-basement $20 FX8300...
One day I'll put some GPU in there that makes it shine, that is, if they ever come down in price.

Re: Lelon quality
Lelon electrolytics are unpredictable, sometimes they do ok in innocuous areas (furnace mainboards for example), sometimes they don't last more than a year in other applications.
Their polymer caps are ok though. I wouldn't hesitate to use them.Leave a comment:

Re: Dell Optiplex GX260 - Advice Needed for Polymodding Motherboard
Just a piece of advice - give some attention to the PSU as well... Dell uses several OEMs for their PSUs...
Depending on the one used in your particular machine, the caps may need to be replaced.
If they're Taicon but don't show outward signs of aging, then leave them (this is not a general rule, just advice for your particular case). If they're LTec, replace, whether bloated or not.Leave a comment:

Re: Modern Samxon and Teapo caps much better these days?
Yes, I have a SP-450 here (SmartPower) I re-capped years ago... There's something else wrong with it. It's in my "PSUs that have odd issues other than caps pile". It works for the most part, but it had some odd intermittent issue which I don't recall that forced me to take it out of operation. I'm currently using a trash-find (again, I remember the street and house where I found it) Antec EarthWatts EA-500D (Delta version of the EA-500). Most of the caps in it were Japanese and I replaced the Taicons...Last edited by mockingbird; 10-31-2021, 09:16 PM.Leave a comment:

Re: Modern Samxon and Teapo caps much better these days?
Nah I find them in the trash... People are abandoning them en masse and adopting inexpensive IPTV subscriptions instead.
The way it works is, if the box was a rental and the person threw it out, it's attached to their account and it's practically worthless unless you somehow trace it back to its owner.
So those boxes get taken apart and scrapped.
The boxes which are not attached can be sold in the classifieds.
Taicon can be good, but good luck finding out who they...Leave a comment:

Re: Modern Samxon and Teapo caps much better these days?
Sorry to resurrect this thread, but I just had to comment on Samxon SK.
Our local cable provider started using these in the cable boxes... Where an identical model would hade had Japanese caps, SK our there in their place.
TheLaw, you make a good point, but now that there's a materials shortage around the world, can Chinese companies be trusted? Sure, Japan and China are shame-based cultures as opposed to the guilt-based culture of the west, but if faced with an electrolyte shortage, would UCC release...Leave a comment:

I would have went about this differently... You're right about JMicron - it's not reliable at all. Someone whos more knowledgable once mentioned that it doesn't even follow the specifications properly...
What you can do is install a PCIe IDE card with a Marvell IC. Marvell is probably the best chip for IDE in terms of compatibility.

Re: Are this caps something special?
I doubt it.. It could be you butchering the traces on the board with the iron... If those capacitors leakes, they may have weakened the traces or pads.
The caps you linked to are fine... I would probably use something like Panasonic FT, it has a higher endurance, and the last item you linked to is out of stock....Leave a comment:

Re: Any more info on counterfeit Nichicons?
I ran a PSU with Behemot's caps for several years, 24/7. They were his custom-ordered 16V 3300uF UCC KZN series. Quite genuine sir.
If you want proof, then that's not a problem (pics, esr measurement). I can't give you leakage current measurements yet though, still working on building that tester....Leave a comment:

Re: Panasonic FC series - leaking? quality gone?
Pay no heed to what brethin said, you were right to post and it is a good post.
Yes, there are definitely issues with FC. I set aside all my FC and no longer use them in my repairs.
For comparison, I purchased some 'recycled' FC a long time ago from China (but I know they are authentic because they have 'patina' on them from the sweatshop where they were removed by someone who got paid with a bowl of rice noodle at the end of the day.
These are fine I think, I don't...Leave a comment:
