There could be several causes of your problem, but top of my list would be:-

1. The driver circuit to the green gun.
2. The Tube

The only way to be sure is for someone with technical knowledge to monitor with a scope the three colour signals into the tube with a constant test signal the same on RGB, if the result is equal signal at the tube, then the tube is at fault. If the green signal is higher, then the problem is going to be in the driver circuit.

Frankly, unless you are an electronics or TV engineer, you will need to get your dealer to look at it.

Thanks for the quick response. I'm no TV engineer but at least that gives me some idea.  At the moment I can live with it.  How much should I budget if it is the tube?

I too have seen Avants with funny coloured screens, and it's almost always a tube replacement. 🙁 That doesn't mean it's GOT to be a tube problem though, it's possible (but unlikely) as Keith says, that it's just the green gun control circuit gone a bit funky...

Yes in theory Alex😉

The problem is that the tube pulls down the control circuit for the Green gun, so when you measure it. It looks like the circuit is broken.(gone a bit funky 🙂)

Thanks for all the help.  I guess I may have to consider the enevitable.  I had a tube changed on a 28'' avant recently and it only cost £400 which I thought was pretty good.  At least I can use that one when the 32'' finaly does give up the ghost.  These are such great TV's I'm really reluctant to just trash them.  I'd love a Beovision 5 but I'm going to wait until they come down a bit.  How good is the picture on a Beovision 5? Is it really worth the extra money to have an HD version?  I saw that 50'' B&O plamsa on ebay recently which I'm sure was a scam, anyone on here buy it?

Which version of AVANT DVD do you have, the easy way to determine is look at the 4 digit type number on the back ?

It can make a big difference to the price.
