Hi
Can anyone help with this please?
Turned cab on this morning - all fine game played correctly.
Left machine on while out for a couple of hours - returned home to a black screen, started the game got music / gameplay but no screen.
Turned machine off, left back door off for a while, plugged back in - no screen and a clicking sound.
Thanks

Think clicking usually means the flyback or HOT is toast. Really not a good idea to leave these old machines on if you're going out, TBH. Chassis can catch fire when they fail, albeit not usually.

I was out for less than an hour, but good advice, thanks.
I thought running them for several hours once in a while was a good thing.

Yeah as said above probably either the HOT (horizontal output transistor) or the lopt. The clicking means it's in ocp (over current protection) mode, almost always caused by the HOT or lopt going (or both). The fact it's gone bad is just one of those things, these chassis are all getting on in years now, even if they've already had some parts changed! If the big long ceramic resistor on the side of he chassis is getting hot, HOT or lopt is the cause. :)

Ok thanks, are there people who can repair this?
