DSE G1928 DVD player PSU failure
Franc Zabkar
the BRC branded electrolytic capacitors on the PSU PCB
(ROCO-V22A.POWER Ver 2.0), if they are able. I've just had one come in
with catastrophic capacitor failures and one burned up resistor.
Judging from the following reverse engineered circuit diagram, I
suspect that this is, or will be, a common problem.

I guess that's why DSE can retail the DVD player for $29!
How much do the replacement caps cost? :->

capacitors?

Foaming at the mouth like that is not a good look.
Go have a cup of tea, a Bex, and a good lie down.

Pity the don't make Bex any more.
I would have suggested he take half a dozen and wash them down with a Coke.
Guaranteed to send him into a head spin. :-) That's assuming he didn't
chunder in the meantime. LOL

Why not just go to Strathfield Car Radios. and get there $19 box. And stop
wasting your time repairing the $29 DSE crap.
mark krawczuk
cost , mayne , he was bored , maybe he lives 100 km or more from a
strathfield, hey and just maybe, he WANTED TO. and why not if its only
going to cost a couple bucks to fix ??? and how do u know the other player
wont bugger up , at least if he replaces the caps , the machine will last a
bit longer.

It cost me about AU$3 for 8 Hitano EXR series 105degC low impedance
types. Needless to say I did the job for a friend. I believe the G1928
players originally sold for $79, and then were reduced to $49.
Anyway the G1928 has been fun to play with. At the moment I've added
an RS232 port in order to upload and download the firmware. I've also
managed to change the DSE background to a nice alpine scene. One extra
thing this player has is a USB connector on the decoder PCB. However,
there appears to be no corresponding USB module in the firmware.
Fortunately the G1928 looks very similar to an Aldi TEV1020 player
which cost $39 and which does have the USB module present in the
firmware (but not in the hardware). Hopefully I can transplant the
Aldi firmware into the G1928 and get a functioning USB port.
BTW, hacking players with Sunplus chipsets is relatively difficult
because most of the available tools are in Russian or Chinese, as are
most of the hacking forums. I spend most of my time trying to decipher
instructions or console outputs. Unfortunately Google's translator
produces some weird results. If a Russian speaker is watching this
thread, I would welcome some help with a few phrases.

That excellent circuit diagram is not my work. I'm sorry if it
appeared that way. It was submitted to eserviceinfo by someone named
"RE_King". I added it to my web site to complement the hacking work I
have been doing on this player.
FWIW, I replaced all the caps with original values, excepting that I
had to use higher voltages in some cases for availability reasons.
These are the caps I used:

One more warning. The same PSU board is used in some Chinese "Sansui"
branded supermarket players (not the same Japanese Sansui brand from
20 years ago).

There has been talk around of the traps of Philthy setting up a
toaster repair franchise. Perhaps this person is the first franchisee,
and newsgroup etiquette comes as part of the training package?

It doesn't matter.
Some of the funnest stuff I'm pulled apart to hack has been cheap crap.
Cheap crap is cheap crap, it's all good.

The same PSU PCB was used in a $99 Sansui DVD player sold by KMart. In
my experience buying a DVD player is a "crap" shoot (pun intended),
whether you opt for a snob brand or a generic. If your only problem is
the PSU, not the optical pickup, then you are lucky. A PSU failure is
usually a cheap, easy fix. I'm also finding that the current decoder
chips get very hot to the touch. As a rule I add stick-on heatsinks to
these chips and the motor driver chip.

I should add that the G1928 handles DivX5 and Xvid right out of the
box, even though the DSE web site makes no mention of this.

I've just had a look at another G1928. The caps are branded "Rubycon".
They are the YXA series which are "standard" 105degC types, not low
ESR. All are still in good condition, but I wonder if they are
genuine.
This is the datasheet:
http://www.szmuchang.com/admin/eweb/uploadfile/20071213103007566.pdf
The measured dimensions of the caps labelled 220uF/16V and 220uF/25V
are 6x11mm for both, whereas the datasheet specifies 6.3x11mm for the
16V cap and 8x11.5 for the 25V cap. The 1000uF/25V cap measures
10x20mm, which is as expected.
