Tray won't stay closed with or without dvd - Toshiba SD-V291 DVD Player/VCR

Have you checked to see if it is off track? Sometimes when these machines get bumpbed, dropped, or fall they can jump track. You have to take the cover off and inspect to see if it is off track when it closes and opens. It should go all the way back on the track when it closes. Be careful not to shock yourself. If it is on when you do it and your hand touches the metal parts inside you can get seriously burned or shocked.

check the close circuit switch inside the system. its maybe stuck, try to wiggle it a bit and it might work again.
the switch is at the end of the tray when it is closed, its a small black push botton swith.
be careful not to fry it when installing a new part

try wen u press the close button with a dvd inside just keep your finger pressed against it until the dvd starts to read then it will come on and your disk day will stay closed

i had exactly the same problem on a LG-RH278H resp. a Medion MD 81733. I solved it by opening the micoswitches, cleaning the contacts and streching the springs inside the switches a little. The Problem was, that one of the microswitches stayed conductive even when it was off/open.

is this the 360 cause i have never heard of a loose tray, try to take it back to where you bought it.

check and replace caps in the power supply as they maybe leaking causing the voltages thought the unit to be unstable.

It can only be repaired by the repair shop I think your son broke a lug on the inside it may need a new tray?

Deliverance

this problem can happen if tray-in sensor not sense. their r a small liver which press tray in sensor automaticly when tray stay inside. liver and sensor location is near emergency exit hole (when u use a pin for emargency exit actually u press this liver then it release try-in sensor). check this liver and its path any pice of cd is their or not. (to check open ur drive cover. to open it at first use emeargency exit hole to open tray then open cover)

you should try inspecting & servicing the tray transport mech first and then the tray sense swt.
