iMac g4 problems when displaying black colour! What is the problem?

Texte:

Hi,

I've recently bought an iMac g4 on Ebay!

I've noticed a couple of things that are really really strange.

All hardware is ok, it boots up smoothly and everything else is ok. The problem is  when displaying pure black backgrounds or deep black colour. I notice blue flashing lines and dots all over the screen (invisible with other colors in the background). What is the cause? Inverter, LCD panel, loose connector on logic board, gpu?

Second question is that The seller said it was a 17", 1.25 ghz, 2gb ram model which should be named powermac 6,1 in system profile.

I've found it has powermac 6,3 which should distinguish 20" model.

I think that previous owner has changed screen and probably messed up with display or something.

Any advice? Should I try buying a new LCD panel?
