MDS-JA333ES

Just went to turn on my MD deck (it's been in standby for years) and the display is not coming on, the deck works fine apart from no display.

Any ideas?

Any ideas if Sony would even have parts for this and what sort of price it might cost?

Could it be cheaper to get another used unit?

Thanks

you could try to reseat the display cable

Tried that and nothing...

If you turn on the unit on in a dark room, you can just make out red horizontal lines running across the display, when you drop the unit into standby they go away. Then come on again once unit is powered up.

Didnt notice that before.

That's the filament wires glowing, a good sign. I can't remember if they still glow in a cracked display tube (they are vacuum tubes), but I think not - been some years since I worked regularly on calculators, cash tills etc. Presumably you don't even get a ghost image on the segments. Probably not the DC bias zener diode on the filaments, then, as I would have expected some ghosting. Most likely cause then is the 35v supply line to the tube drivers. Has the recorder had a knock? I know some models suffer from cracked PCB tracking when the AMS knob gets a hit, as the boards used are only SRBP and crack easily, especially near screw holes and the like.
