What's that smell?

[Big Phil]

Flicked on my Star Wars Data east whilst I was chatting without looking at the machine. After about 30 seconds I could smell something burning. Turned around quickly and noticed the DMD wasn't displaying. Quickly knocked it off.

Turns out a fuse has blown. It's a .5A Can you get these from the local B&Q or somewhere like that?

Maplins would sort you out.

No chance in a DIY shed.

Its a 0.5 A Slow Blow/Time Delay fuse.

Try Maplins or similar electronics/electrical place.

Will try tomorrow. Thanks!

Awwww man! It's still poorly. I replaced the fuse and the same thing happens. TR3(Black cover with screw towards top left of picture) sparkson the underside. Looks like there are a couple of solder points. Maybe they're shorting? You can see it's slightly scorched underneath then the fuse slowly burns out.

Something not right then at TR3 transistor - shouldn't spark :eeek: . Guessing at minimum this will need replacing.

And TR1 as the pre-drive tranny...

I've taken the board out and I've opened a can of worms. There have been some botch job repairs done to the board in the past.

Connector CN1 has had a pin burn out so a "repair" job has been done on the back of the board. A couple of wires soldered on to the board and then to the cable for that particular pin.

Think I'll just go for a replacement board. Anyone got one for sale?

Pretty common for some burn up repairs on those DE boards.

These guys do a new design replacement

Not in this country. And none in stock. Any chance of finding a spare in the UK?
