Whites repair ?

[Koala]

It just decided to no longer turn on.
Cleaned all the terminal points, and tried 3 different battery packs, but no luck.
Few years ago now, & I replaced it with a Equinox 800 which I'm more than happy with, so I'm not desperate to repair it.
It'd just be good to have a backup though, as I've had a couple of occasions when a friend has joined me & it'd have been nice for them to have a machine, rather than just stand watching me.

Most of the intelligent bits are done within firmware and there's not a lot I can do about that

The PI that started this thread I am very confident with, even if with the water damage, I have built the surf and barracuda PI from scratch

I am less confident with yours, if you are around Cheshire you can drop it off for me to have a look at free of charge,

Just about everything is tweakable, so with some playing around it should still hold its own with more modern detectors

That's very kind of you to offer Koala.
I must admit, my original post was made slightly in jest to the fact that you were suddenly going to get inundated with White's owners wanting their faulty machines looked at.
(Mine packed up about a week after the service centre in Inverness closed!)
I'm in Yorkshire, so not a million miles away, and may take you up on your offer if I'm passing that way, but I'm not desperate so won't make a special journey.
Thanks again for your offer though

Thanks for your offer koala.
Have sent you a pm.

Had to clear some jobs off my bench first

But taken the PCB out and had I quick look

Looks very repairable

There's very little corrosion or arcing all fairly minor

The board is the same as I posted earlier,

Mostly working, battery test works, plus and minus 5 volts present and correct, headphones fine, coil fine

The two main transistors measure fine in circuit, resisting lifting them out at the moment as the holes are very small in the PCB

Put a oscilloscope on the output tomorrow if I get chance

That about as far as I got before getting side tracked with visitors

Great news thank you. Merry Christmas.

Finally everyone left me alone and I cleared some space on the bench

Some good news it's back working again and with good depth

Just doesn't seem 100% reliable at the moment

Could be just because it near electricity and a metal bench

I got some temporary work that needs soldering properly, I will resolder the board and take it for a test drive outside but fingers crossed it looks okay

That's great news. Much appreciated. Please pm when you're happy it's sorted.
