Why won't the drawer for the CD player on my under the counter trutech TV open?

if it opens back up when you close it the drawer mechanism is probably out of alignment. Most players have a slot on the bottom of the drawer that a pin must slide in. Look under the drawer and see if there is a pin sticking up that maybe should be in that slot.

the cd drawer will probably use infra-red to sense when the drawer is open or closed or maybe just a gear mechanism, either way these must be clean, I'd take it apart and lean it all with cotton buds and isopropyl alcohol

Half the battle can be won by just dropping a CD in and pressing Play. It WILL close.

We took it back

Remote control for under counter cd player model KC308S destroyed. need to buy a replacement

you will need to take your brand to a techn to change the main motor of the drawer. the motor is not working.

the cd drive should have a tiny hole under the drawer. push a small screwdriver into the hole and it will release the drawer.

my video stoped and the door will not open
this is the second this is happening to
please help me open door

Only a temporary solution....
Target sells a scam with their Trutech brand, this entire line deserves a recall, nobody is getting support or refunds. NOTHING. Target deserves a class action suit against them.
In the time-being, your DVD player probably still can play movies, just that the drawer gets stuck. What is happening is, the mechanism that raises the DVD to be scanned when the disc is in doesn't lower properly so when the drawer is supposed to eject, it is held back. You can manually eject this.
The cheap flip-down door is flexible so when you press the center of it, the outside edges become bowed and can be pulled down with a fingernail. Under the drawer (you may need some light to see for the first time), about 1/2" from the left inside, there is a black plastic wheel. Using a paperclip, you can catch the "teeth" on this wheel and turn it counter-clockwise (from left to right) and this will lower the mechanism and likely your tray will automatically eject.
You might be surprised that after this, your tray will open and close fine consecutively by hitting the eject button. But keep in mind, the problem is the mechanism that raises the DVD to be read is what holds back the eject from working.
Do yourself a favor and scream at Target. Make yourself heard, everyone is having problems with this line.
