[QUOTE="Steerpike, post: 87825, member: 807"] If it changes depending on tempeature conditions - it sound like a failing component. The simplest way to locate it is to buy a can of freezing spray, from somewhere like RS, Rabtron or A.P, for example. http://za.rs-online.com/web/search/searchBrowseAction.html?method=searchProducts&searchTerm=freezing+spray&x=0&y=0 Spray the electrolytic capacitors (i.e., generally the vertical cylindrical ones) in the power supply in sequence , and ones on the video processig board in turn, until you find which one fixes or worsens the problem. If you are lucky, you will even be able to see failed capacitors since they sometimes bulge & split open as they die. New capacitors are cheap - around 80c to R8 depending on the value and voltage. If you are unlucky, it isn't a capacitor at all, but an integrated circuit; that is still repairable but requires quite a bit of talent in the de-soldering department. [/QUOTE]
