psu clicking

[ncamacho2000]

Hi all

I have a 2008 6040 and noticed some banding on an engraving and then the PSU started cicking when i ramped up the power, i have since noticed some arcing inside the unit near the negative wire and turned it off straight away.

I have had banding issues before but HPC changed the tube and seemed to go away, does anyone know if a faulty PSU could be cooking my tubes too???

Thanks in advance

1st of all, check all the wire connections are good and tight - if you are comfortable doing that ?
If not, get someone else to have a look.
The transformer output can remain charged for quite a wile after it is switched off
