Popping capacitors Who has post 2006 hardware with bad caps?

I bought a bag of 30 1500 ľF 6.3V nichicon 105° caps from China on
Ebay. The caps were $10.99 and shipping to Sweden $5.99.

Here is one such auction:

They shipped quickly, ~1 week, and the price is very reasonable.

I have no affiliation with them, other than I'm a happy customer.

I have also bought LED:s from another chinese vendor, and I'm very
happy with these as well.

The vendor didn't state they were Nichicon though. Seeing as they come from China, I'd be suspicious of their potential origin.

But they don't have motherboard caps, only normal 10mm ones.

You're confusing size with application.

I replaced some buldging caps in my old cheapie MOBO
with nichicon equivalents and the board still runs great.


That said, there was a genuine issue a few years back where one
(or more ??)
of the major electrolytic manufacturers had a batch of 'fake'
electrolyte
swung across them, which resulted in hundreds of thousands of
substandard
caps appearing on the market, and finding their way onto
computer
motherboards, and failing after a relatively short period of
time.
Obviously, the mo-bo manufacturers thought that they were
buying full spec
caps, and the cap manufacturers thought that's what they were
selling, so
not a penny-pinching situation in that case.

I just recapped the power supply of a Cyberhome DVD recorder
Click to expand...
(manufactured 2005?). It's a pretty nice unit that I got for next to
nothing ($25). Two 2200 mf caps were bulged. The unit was exhibiting
lots of strange behaviors; display scrambled, erratic remote
operation...and finally complete failure to function at all.

OTOH, I expected all of this based on web research of the unit. This
particular unit (DVR 1600) has some pretty well-documented shortcomings.
It also has some pretty neat features, reasonable performance, and can
be had for a song.

In addition, I heatsinked the regulators on the board (one even had a
silkscreened outline of a heatsink on the board, but none installed),
and added a cooling fan. I think the fan might have been overkill--the
real problem being the result of only *10v* rating on the original caps,
but better safe.....

It's now working like a champ. I'd like to find a BIOS upgrade for it,
but I haven't located the download. Cyberhome is defunct--no factory
support--but reportedly there is a later version.

mF ? You mean it has 2.2 FARADS of smoothing ?

Do please use the correct terms. I assume you mean 2200 uF.

m = milli = 1/1000

Wow! You figured it out. I wonder if anybody else did?

On my last 2 TFT monitors teapo and jackcon, on the power supplies it's
tah-ken and fuhjyyu (fake fujitsu?).

Fuhjyyu isn't fake Fujitsu. I may be wrong, but I believe Fujitsu
makes only solid caps now.

Why does Fuhjyyu use the round Hitachi symbol?

Unless someone knows a good supplier for 105° caps suitable for computer
who has no objection to ship to or is located in europe.
Any suggestions, i would like 1000 or such of each common number.

RS Components, http://rswww.com

Farnell, www.farnell.com

Both located in UK and will ship to mainland Europe. I have used both
to obtain caps for motherboards (including hard-to-find 1200uF and
1800uF ones.)

Hi All
As per subject really. I have the user manual and service manual, but I
need the schematics to debug a start-up issue.
This unit has been out of support for 12 years. But it is (well, it was!)
a damn good unit.



You can buy a copy of the schematics manual for this unit from:
http://www.manualsplus.com

It ain't cheap!!!

Thanks for the link. It's only $60. And if that keeps it going for years to
come, it'll be worth it. A 500MHz sig gen of this spec costs much more than
$60!

The unit has started working again after taking it apart and re-seating a
few cables. Fingers crossed.
