Sounds like it doing a auto deguass you could try looking in the on screen displsy propeties to see if you can turn it off.

Checked that Aco... no auto degauss tho I admit thats it sounds like it is degaussing.. all crt's make a clicking noise at start-up.. might be the thing that starts the monitor(a relay of some sort???) that is working its ticket or out of adjustment... i'll have a look on the Compaq site... cheers for now

I had a television that behaved similarly. One day, the "thump" was twice as loud as usual and that was the end of the television.

Some capacitors in the EHT circuitry failed. This caused a short circuit on some other part which caused something else and so on. It just wasn't worth repairing.

We had a number of Sony and Illyama monitors that had this problem. Their life expectancy was no less than non-thumpers. We ran them for several years before upgrading to TFTs.

So is it a case of "live with it"?

Live with it?
Christmas is coming
Get an extra large sock you never know you may find a nice TFT in it.

also dont let us get into the TFT/CRT debate..thanks all ..I'll keep prowling around the web .. must be an answer somewhere,, the trouble is the picture on the monitor is pure dead gorgeous ... just that annoying thump is a bummer

It's just the mains surging into the thing, I think. If i think any more, I'll let you know.

Dont turn it off. We leave all our monitor on 24-7 just us the pc display settings to blank the screen after about 15 min of no activity. They still last for years.
