Hey,

Been fiddling with this for a bit and guess I need to post it here.

I have a PCI ATI All-In-Wonder TV-out card and the special cable that
goes with it. That's connected to a new SANYO 24" TV from my PC
running Win '98 - using all this for MAME.

Now, after being on for about 3-5 minutes, you can see two distinct
areas on the screen that look to be getting a "washed out" look -
almost like the screen needs degaussing. It's not a degaussing
issue,
tho. Then, as time goes by, they go away. Then, of course, they
fade
back in. Kinda distracting and unacceptable for a new TV. The best
way to describe where on the screen these appear - get ready for it -
if a woman stood in front of the screen, centered, and pressed her
ample chest up against the CRT and left two impressions there -
that's
where the areas of discoloration come and go.

I've tested the TV with my XBox (composite)- no such issue. Tried it
with my DVD player (s-video)- no such issue. So, I'm ruling out the
TV
itself being fux0red.

So, it just seems to be the computer/vid card. It does it with
either
S-Video or composite output.

Wondering if it's a simple matter of adjusting refresh or resolution
(trying all of that now) or I should buy another video card. I
wouldn't think it's a driver issue but you never know.

Anyone seen this? I get nothing on searches for this specific
problem.

TIA.

BTW, the email is no longer valid. Replies here appreicated!

I have seen two ATI tuner cards and one of the All In Wonder video
cards
suffer from bad electrolytic capacitors. One of bad capacitors is in
the
tuner AGC circuit which can cause washed out highlights. These are
thru-hole
components and are easy to replace if you are into fixing electronics
and
have an ESR meter to find the bad capacitors.

Interesting. Checked the ATI site and did some googling, but can't
find any schematics for these cards. Anyone know where to get the
schemes? Replacing a few caps is within my realm of capabilities -
used to collect/repair arcade games.

Well, if that's it, I can't replace those kind of caps. Damn small!
Anyone else with suggestions as to the potential problem, just in case
it's not the caps?

The AGC cap is inside the shielded tuner module. It is an electrolytic, is
relatively small, but not the very tiny surface mount caps you are probably
seeing.
