I've got two VHS players. One works fine.
The other is a Philips VR 608. Been used very little. It was bought purely to play NTSC VHS tapes - my main machine, a Panasonic S-VHS wouldn't.
On powering up, get the welcome screen. Can select the setup menu too. Connected via SCART, selecting that input routes the TV video and audio back to the TV. Tape loads and runs - but no pic or audio. Checked the combi head with a baby bud and AF spray - perfectly clean - as is the entire inside.
With something that age I'd suspect the PS, a SMPS. But no test points marked on the PCB. But since the electronics mostly work and the motors etc too, could there be one supply not working?
