Daewoo SD3500P VCR+DVD player, 2004

Supposed to be just changing the tray drive belt. Press DVD select button on the front panel, and DVD legend appears in the display, but no sled,tray movement or laser. ovrlay 12V line for 5V VR, overlay 5V line for 3.3V VR and overlay 3.3V for 2.5V VR all present. The user manual has use of r/c only , no reference to the selector on the front for remoteless basic play, and I've no r/c with this machine. No response to open/close button. Anyone come across a machine where you cannot use simple front buttons , although physically present and wired up.

Failed SMD ATC 17-25, 2.5V 1A VR on the DVD pcb. Giving 1.1V in circuit,

2.5V no load. With a 4.7R load only 0.1V. Robbed a topcode N13A, 117 type 2.5v .8A VR from a video card and DVD back in operation via fron buttons. The slack tray belt was just a bum steer.

Well, sony had some commercial VCRs with a key inhibit switch that locked out most of the front panel. Obviously not related to your problem though.
