Hi, After 6 years of pleasure our 56WH08B has stopped giving a picture and the Standby light flashes Green/Red. If I unplug the TV and plug in, now and again it will give a full picture for a minute or so before going back into standby mode and flashing Green/Red. 1. Has the lamp gone / about to go? 2. Can I change the fuse in the interim? 3. Is it easy to change the fuse / lamp? 4. Where should I get the fuse / lamp from? I know not many ppl have this TV, so any help will be truly apprecited!! Many thanks, Sonny.
