After power outage front display blinking "16".
I had a similar issue where after a power outage, the player would not power up.
I removed it from power and took the cover off looking for a fuse. Could not find anything so I put the cover back on and plugged it in and it worked. My theory is the electronics needed time to fully discharge in the circuits. I would leave it unplugged for about 24 hours. I left mine unplugged for several days. I hope this helps.
Toshiba sd-3990 Disc-drawer won't open
I was given one of these the other day. I was told the drawer wouldn't open yet the machine seemed to function fine. I removed the six screws holding the top on the box and then removed the four screws holding the drawer assembly in place. As you lift the drawer assembly out of the box, make sure you release the two pieces of black retaining tape holding the data cable to the box floor. Turn the drawer over and you will see that there is a little sideways bar mounted on the front underside of the drawer assembly. This is sticking. As you press the OPEN button, jiggle this bar and the drawer will open. You may have to manually move the drawer cogwheel a little to help free it up. Hope this helps.

Disc won't spin
Check the spindle motor (this is under the disc table - which the centre of the disc sits on). If it measures open-circuit, it is faulty and not economical to replace, or (in rare cases) the voltage rail to it is short-circuit (it is more likely to be the motor itself which has failed).
If it is simply siezed, carefully lubricate its bearing (the base of its shaft just under the disc table) with some RP-7 or WD-40 spray (available in most auto shops) or CRC electronic switch lubricant (this is also a spray like WD-40 but also cleans contacts as well as lubricates), while gently rotating (edge of) the disc table in both directions. Don't get dirt and grease on the top of this - or it will transfer to discs.
Don't use too much of the above spray cleaners. A little bit is all that is required. It may or may not fix your problem. ONLY do this if your player is not under warranty; otherwise submit it to an authorised service centre and get them to quote for any replacement parts and labour involved, then decide if it worth repairing or cheaper to buy another player - up to you.
You should only consider replacing the whole unit as a last resort when you have exhausted all other possible options.
Player will not read discs.
Easy option first , clean laser with a laser cleaning disc ,if that doesn't work then (I assume you have tried more than 1 disc). a laser won't read a dirty disc, you may have a laser mechanism fault ie laser sticking in its tracks. you could try oiling the cradle that the laser sits on. other than that it is a costly repair.
DVD will play but not
If the unit still plays dvd's then the laser diode used to generate the laser for the cd's has been fried - when you unhooked the cables a static spark was generated and it has fried the diode, and strangely only it, it happens.
You can't fix that easily - the diode is in the laser head and it's a sealed component that isn't sold separately. You must find out a replacement optical unit and change it as a whole. Unfortunately the mechanism isn't sold as a part so the only source will be a defective unit.
DVD player won't play DVD, says "load"
The unit can recognize that a disc has been loaded but can not read the contents. This can be as simple as a dirty lens or more drastic like failing optics. Try cleaning the lens using a cotton swab and alcohol. If that fails to correct the problem and a music CD will play OK, then the optics are failing. DVDs require more laser power to read than a music CD.
I have very low volume when i go to play a dvd on
Press the Audio button
on your remote to toggle between different audio modes(Stereo, mono, dolby etc.,). Atleast one of them should give you a proper audio level.

No disc message appears
Just re-seating the flat cable, many times, didn't work for me. Instead, I very carefully cut about about 1mm off the end with a straight, smooth edge scissors. Then I plugged it in, pushed the clip down, and it worked! Be sure to cut straight, or the fine pitch contacts might not line up.
