Tech - Colour vector monitors ...

[ukvac] Tech - Colour vector monitors ...
How bad is it???

I turn on my space duel for the first time (voltage converted to 240v) and almost crap myself ... there is a very load "cracking" or SERIOUS arcing sound from the monitor area of the cab.

This is not the normal hisssing or buzzing of the HV, this is LOUD and SCAREY! Anyway, I turned it off in around 2 seconds after power-up.

Any ideas? Dead flyback? I wasn't going to wait around to see if I had heater glow!

Reassuring words would be nice, failing that the truth will have to do!

Cheers,

Steve

Was it accompanied by any fumes or smoke of the "Exploding cap" or
"About to explode cap" kind???

I did simliar with an old Hantarex PSU and was treated to what can only
be described as a firework display with smoke instead of sparks )

If this is the monitor that you mentioned earlier (19V2000) then it
would by my guess that the guy would have been very right in suggesting
replacing the caps before plugging it in ), or should that be (

Sorry they ain't encouriging words! Look on the bright side, I could be
completely wrong!!

Hang on, Space Duel - that's color. Can't be the 19V2000 can it?

I still stand by the sound of capacitors taking a turn for the worse
mind...

is it dusty in there? sounds liekthe anode cap could be loose, or has found
a path thru some dust to give you the nice crackling noise..

Luckily? not the 15v2000 NOS monitor ... this is a WG 6100 19" colour vector!

I didn't smell anything that didn't emerge from my trousers!

Re: Re: [ukvac] Tech - Colour vector monitors ...
The monitor is not clean but not really any worse than an average cab ... having said that, it probably hasn't seen power for a long time.

I'll pull it, check the transistors, check the LOPT with a ringer and give it a good clean before anything else! I knew I built that LOPT tester kit for a reason!

Thanks for words of hope!

RE: RE: [ukvac] Tech - Colour vector monitors ...
This raises a fair question actually!

In this (or similar) events, what exactly should you do??

My reaction would be to switch it on (and off again quickly) for another
look, but actually facing it this time (maybe having put some glasses
on!), BUT I know this is the WRONG way to go about it really )
