From: D Yuniskis on 1 Feb 2010 21:08 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! --don

Anything beyond a blown fuse or broken connection makes most of these unfixable by mear mortals. :) -- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

Could be a protection device open 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?) > 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.

I note the unit had an extended warranty (sheesh! when will people learn??!) on it -- that expired 3 weeks ago. :>

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. :) -- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.
