Hi !

I have a problem with my VH4.
Here the signal path : guitar --> Diezel VH4 --> Diezel 4*12 RL

the guitar is OK (my tuner find the signal).
All my cables are OK (tested).

When I push up the volume, I can hear a "hummm", but no sound.

All tubes are light up, all fuses are OK (no lights near the power tube fuse).

Do you have an idea to fix my problem ? :aww:

Thanks !
 
My speaker cab is OK.
How I can check the cabinet ? I don't have another amp to plung into it.

Main fuse is OK, and I think power tube fuses are OK too (no red light).
 
Have you checked the mains fuses?
edit: sorry, it's not this, that will cause the amp not to turn on.
 
I checked all these things again (except the cab), and I still have a "hummm", du no sound.
One week ago, everything worked fine :confused:
 
Can you change the channels by pushing the red buttons on the front of the amp?

Toggle the mute button a couple times for good measure.

Be careful and dont plug your guitar into the "thru" instead of the "in".............


I have seen it done before....... :doh: :LOL: :LOL:
 
Standby off, yes?
Mute switch - make sure it's not engaged.
Speaker/cable connections - make sure they're FULLY engaged into their sockets. Sometimes they don't latch perfectly.

They're fully engaged. I have tested and checked the speaker cable, but I will buy an another to be sure.

Do you have something in a serial loop that could block the signal ?

That's a pretty good shout actually. This happened to me the other day. I had one jack not fully engaged into one of my effects. It interrupts the whole signal path.

Thank you very much :thumbsup:

The problem was my Hartlan flanger, in the serial loop.
I have an another problem now, but serious less.
