Default Toshiba SD-1700U DVD with distorted audio

Not a problem. Here's a little more I found on this.

"I fixed my SD-1700 Toshiba with the replacement of only one capacitor,
on the main board, that had a 25 ohm leakage. This bad cap caused a
disruption of all the regulated power supplies and that will affect
the front panel display and just about all the functions of the
player. My problem was just the loss of the front panel display and
I think that it was Mark that clued me in on the fix. I tried to get
a schematic for the player from Toshiba but they only sell it on DVD
for $50. Quit arguing and just replace the caps-------it costs less
then a buck.

I have read other messages about audio problems with this player and
they all seemed to center around bad capacitors on the main board. I had
a problem with my 1700, it was a loss of front panel display, and I
fixed it by replacing a shorted electrolytic on that main board (it
caused a loss of the regulated power supplies). I think that it would
be best to start out by checking all those caps.

Actually, I'm not the one with experience on these, but I've seen lots

of
posts on these Toshiba's and I've tried to re-post info I've found.

I'll be right back with the info.

I recently acquired two Toshiba DVD units; model SD-1700U that are
experiencing very distorted audio. I have followed several postings
regarding some of these players with bad or no audio, but I am still
uncertain what needs to be replaced, component-wise. Is the problem on
the PC-Main card or the Pwr-Sub assy board? Any would be very
appreciated.

The biggest problem with this model is the caps on the "main" board.
If you have a capacitor checker check all the caps on that board but
if the only thing you have is an ohmmeter than use that. The
schematic is very hard to come by as it's only available on a $50 CD
from Toshiba. Also, you might try to "ping" Mark Zacharias, he is
familiar with the problem.

Sorry!!!! I had a problem with my unit quite some time ago but lost
the correspondence that I had with the person that helped me out. I
really thought that it was you. Sorry for puting you on the spot.
