Urgent help on iMac PowerPC display problem.

I have had my imac Power Pc G5 for over 1 year and my screen has started going off colour, as a photographer this is a big problem that i need to resolve fast... Can anyone help?

The screen goes fuzzy (like interference) then it goes a light tint of blue, sometimes it reverts back to normal after a few mins but most of the time it stays blue for ages the sometimes goes red. I have been told to take the back off and hoover it out (so to speak) but this does not seem to resolve the problem. It is out of warranty and to get apple out it will cost me £95 for them to even look at it (not including fixing the problem) I have thought it may be a graphics card problem but do not want to buy a new card to find out i have wasted my money and he problem is still there.

I have looked on the forums but have not seen anything similar to what i am experiencing, has anyone else had this type of problem??? As i said i need this sorting asap.

Oh and I am using OS X 10.4.10 and calibrating the screen does not solve the problem, it just alters the tone of the tint

ANY HELP WOULD BE GREAT...

Cheers.

 

No it does not, thanks anyway.

 

My imac is 2 GHz Power Pc G5, 512 MB DDR SDRAM, I will have a look on the net for a service manual now. Thanks.
