Cabs in storage - not working

[RetropiVin]

I was talking to a friend that has a few cabs. They were working when put away but after about 10 years in storage they are not working. I am assuming the issue is the crt's. If it is them, would this likely be a recap project? if so is it difficult as a diy job. Note, I know there is a high voltage issue and will have to take advise on how to manage this.

If they've been in storage for 10 years it could be anything. Dodgy PSU's, batteries died on the PCBs etc.

Disconnect all pcbs at least, and test voltages, those are your expensive parts to replace.

Depending on the value of the cabs, it’s not something I’d go playing about with.

Try and compartmentalise you’re issue. Have you got a SuperGun or a cab that’s working?

If so, take the boards out and test them and see if they work. If they do. Keep them to one side and get a cheap substitute board in there to test. Making sure your pinouts are the same.

You can disconnect your monitor via the molex and test your power supply voltages at the molex outputs to see if you’re getting the correct voltages.

If that’s alright then get it all connected and check your monitor for output. Take picture and post them on here for diagnoses

What I would say is it’s probably the absolute worst time you could be firing up cabs that haven’t seen the light of day for a few years. Very cold old cabs pumping electricity through them for the first time in a while is likely to to crack solder and give you other issues.

Monitor stuff, get pics, diagnose, send to Gunblade. If it costs you £100 a chassis it’s money well spend depending on the cab.

The cabs are generic type ones - I think with cheap boards and I dont have a supergun, I can do a bench test.

I will see how I get on but given that they are generic it might be easier to replace monitor if required.

Thanks guys.

get the monitors repaired.
its no big deal (usually)

It depends where they are stored first, if it's some old damp barn then could be trouble but if there somewhere dry at least probably not much wrong

I've had machines that people haven't tested in years just been stored and they fired up straight off and working perfect, if they are somewhere cold need to get them in warm for 24hour before doing anything

Yeh its a matter of Visual inspection first realy and then firing things up separately to see whats what. Not always easy when they have been stored for 10 years. I doubt they will fire up, but depending on the condition I suppose.

Storage places are bound to be damp and cold so I would do as Bods says above.
