HELP!! My Sony plasma PFM-500A3WE is playing up after 2 1/2 years of faultless service (Yes only had warrenty for 2 years ). The problem is that it switches on and off and the on/off light flashes a deep red. I looked around the side and there's a "service code" LED display, it's flashing 22 then 12. Any ideas? Does anyone know what this service code means? If I unplug it from the mains for say about 6 hours it's ok for a while, but plays up again later on. Is it dying? Any advice on where I can maybe get it repaired (or seviced?!?). I live in the Bristol area. Any advice would help to increase the length of my marraige! Cheers.
