Was doing a bit of DIY and turned the electrics off at the mains but forgot to power down the VU:bangshead:
Now it won't boot up,get the red light on for a second or so then nothing,tried a different PSU,still the same.Only thing I've noticed is the on/off switch 'arcs' where the spade connectors are on the switch?
Any ideas?
Cheers
 
Try a USB image flash

Doesn't power up edogg,bought another switch today but does the same thing as the old one,it 'arcs' on the spade terminals.
I'm a bit stumped with this one?
 
I have had many power failures and they have not damaged my vu2 plus do they have power fuses like a tv

It the capacitor on the motherboard itself that need to be replaced.

807 is the one to replace see this photo

Already done it before Ferret,do you think it's gone again?
 
you can slap a bigger volt on but keep the same resistance ect

strange if its the same cap ?

Worth a try as you know the symptons are the same it could also be the voltage regulators. Never purchased any of those mind you so im not sure where to get then.

I'll buy another,got the last one form Maplins,cheers Ferret
 
From my understanding of the original post, if the Red light comes on for a few seconds then goes off "[FONT=Open Sans, sans-serif]red light on for a second or so then nothing"[/FONT]

[FONT=Open Sans, sans-serif]I would be inclined to be looking at your power supply.[/FONT]
[FONT=Open Sans, sans-serif]Check all voltages from the PSU to the Main board (voltages are shown on the PSU)[/FONT]
[FONT=Open Sans, sans-serif]Take care though as there´s mains voltage on parts of the board though obviously

Right,changed C807 cap and a couple of others that where 'bulging',still no joy.Checked voltages on mobo,nothing.Checked the radial fuse on the PSU and it's blown,just going to order some off fleabay.
 
Oily, If your radial fuse has gone you won´t get your red light at all.
Worth bearing in mind.
I´ve also sent you a PM you may find interesting...
 
mine had the red light and starting and was repaired,now gone again and red light showing.
 
Right,I'm not getting any voltages at the white multiplug which plugs into the mobo?
Any ideas?
 
If there are no DC volts of either 3.3, 5, 5.5, 12 or 33 volts from your power supply and your unit suffered a blown fuse, it´s fair to assume you have a fault with the Hot primary side of your PSU (the 240v side) fault finding could be a real challenge. if I was you I may test the bridge rectifier but if that proved OK (and I expect it will) I would continue with plan B as discussed via PM

Was going to say one side is dead,the right hand side in this pic
Which is the bridge rectifier Dave?

Oily mate, the Low Voltage right side is dead (as in your picture) because there is nothing from the 240v mains side getting to it, problem is, I´m not happy getting you to probe and fiddle to much on the mains side of the board (the big Capacitor alone has enough charge to give you a shock if not discharged!!) short that with 2 screw drivers to be sure before you continue.
The bridge rectifier looks like this

A quick google will tell you better than me how to test it.
Also just sending you another PM
 
Well I bought a rectifier bridge but still have the same issue so moving onto plan B :)
