Re: 2005 tyan motherboard capacitors

Could we see some pictures of your board? Perhaps we may be able to spot something that you haven't.
I don't think the polymods could have killed a MOSFET or a regulator... but if push comes to...

Re: Got 4 LG L222WS 22" for free - psu recap

... which is better, IMO.
I strongly prefer 16:10 monitors over 16:9... and 1650x1050 is a really good fit for a 22" screen - at least to my eyes (I don't like really high resolutions that make text...

Re: LG L1715s with failed Samxon GF

Hey, terrible caps or not, that's still way better than where this monitor was headed for. At least now it gets an extended lease on its life, even if only for a little while until the replacement...

Re: Nfren nf-1500ma

LOL, them old LCD monitors were pretty thicc, weren't they? :D
Aside from the crap cap brands, the rest of the build quality looks pretty good.
Generally these older monitors weren't as susceptible...

Re: LG Flatron L207WT repaired

Nice work! :)
... and wow, a lot of patience to swap so many parts between so many monitors around. Pretty cool, though.


I have actually found a really good solution for that: drill holes in...

Re: Learning to repair monitor's PSU

LCD monitor power supplies operate the same as any other Switch Mode Power Supply (SMPS.)

Component (1) [bridge rectifier]: turns wall AC voltage to DC voltage
Component (2) [capacitor]: stores...

Re: can a flyback transformer for USB charger isolate?

If it is what I think it is... I've done it, it's supper easy, and works 100%... but I've only had good success with ATX PSUs.

Basically, take any old crappy ATX PSU (but preferably one that won't...

Re: Universal LGA775 VID mod question.

Thanks for sharing this!
I find it quite cool how all of the VID pins are so conveniently located next to a ground pin, as if asking to be pulled low by this mod. :)

Re: sancon china caps

Sorry I didn't put enough details in that post.
By "better ESR and ripple current", I meant that the replacement cap should be rated to have same or lower ESR and same or higher ripple current...

Re: Failed Panasonic FL

Yeah, that's what happened most likely.

Even Panny FL can take only a finite amount of use/abuse before they fail.

Now I can't recall if this was with FJS or FL series, but I also had a...

Re: sancon china caps

Well, increasing the voltage rating on a cap will net you higher ripple current and lower ESR (due to larger can size compared to a cap of the same brand and series, but with a lower voltage...

Same here.

Re: Bernina control board

Even if the transistor is bad (or not), I still think the caps that show short-circuit on both sides are the ones to worry more about.
I don't have a LeakSeeker either, nor a good enough lab power...

Re: Repurposing a 2004 Athlon 64 system in 2021

Ah, so you have an Athlon 64 3500+. That's a pretty decent overclocker CPU.
Running at 2.2 GHz and 200 MHz bus, that means it has a multiplier of 11x.
Not sure how far you may be able to push it,...

Re: Modern Samxon and Teapo caps much better these days?

I've only seen CapXon KF with black sleeves and silver printing... but I don't think that really makes a difference, since I've seen CapXon use other colors for their KM series (e.g. Apevia/Aspire...

Re: My first TFT repair - Nec LCD1703M

Re: Hard drive reliability

Holy-moly! 119k POH?! :jawdrop:

I always knew those 80 GB Seagate Barracuda 7200.7 HDDs were built like tanks... but that lifetime really is something you don't see every day.

Re: Power supply build quality pictorial. part 2

WOW!
This must have been one of their earliest ATX-compliant designs.
I mean, it has a regular transformer for the 5VSB instead of a switching circuit - that just says A LOT about this PSU's age....

Re: Dead but clicking Hanns-G HC194D?

I agree.
Just remove the 7812 regulator and see if the PSU can start up.
To remove the 7812, first unscrew it from the heatsink. Then, using a sharp blade or flat screwdriver, separate it from the...

Re: The (now the death of) Dolby DP600 Build (OK, this one is BEYOND COOL)
