Toshiba portable DVD player

[D Yuniskis]

Hi,

A friend dropped off a Toshiba SD-P1900 portable DVD player
for me to look at. No mechanical sign of life -- power indicator
successfully illuminates to indicate charging vs. charged.
Backlight illuminates screen as power is turned on (enough
to show the screen has no blemishes, etc.).

But, no motor activity. Nor does the optical pickup move
on its carriage.

I think these things are cheap enough that this one should
just find its way to the recycle bin? (a shame as it really
is pretty!)

Thanks!

I'd start by tracing the voltage back from the deck to the regulators
on the pcb. Could be a protection device open
-B

Also, you can pick up parts units on eBay dirt cheap. Something with a
bad drive or screen but good mainboard might be the easiest way to fix
yours. Anything beyond a blown fuse or broken connection makes most of these
unfixable by mear mortals.

Hi Reverend; Sam,

I'd have thought I would lose the backlight, charging/charged/power
LED, etc. as well with such a failure. I think it more likely that
the motor servo amp is toast -- since neither the head positioning
actuator runs *nor* the spindle motor. (I think these amps
run both?)

Yeah, I am more inclined to just toss it than throw money after it.
I note the unit had an extended warranty (sheesh! when will
people learn??!) on it -- that expired 3 weeks ago. :>

Well, by "dirt cheap", I've picked up parts units for $10 or $20 delivered.
Most problems were trivial to remedy. They weren't that precise model, but
of 6 or 8 I bought, 1 became the donor and supplied parts to fix those
that required more than duct tape to repair.

Late to this thread - but I'd certainly check the lid switch. It will never
focus or home the laser or indeed even run any motor if it doesn't see the
lid closed...

Aside from backlight, nothing on the screen.

Hi Mark,

The only thing that may be working is the backlight and lid switch.

Normally, the Toshiba DVD players will display a welcome screen even if
the DVD drive is dead.
