when a television turns off by itself and flashes as you say, it indicates that there is a problem inside the tv. If you keep trying to turn it on you may do more damage. It could be something as simple as a faulty fuse inside. If you have no expierience with electrics I suggest you get it checked out by a professional. I had a similar problem with another tele model and it was the fuse in the back of the tele that needed changing. I did try to this on my own but unfortunatley didn't have the right fuse so i took it to a repair shop and he done it really quickly.

it sounds like you could have a signal board problem they are pretty expensive but there is a web site that sells refurbed parts

Thank you for the help. I actually changed the whole main power supply board and it still did not fix the problem. When I put the new one in, I had the tv on for about 3 hours and then I shut it off. No sooner did I get it back up on the wall and the problem started all over again.When I pulled the original board, the caps all looked fine so I am not even sure the board is bad. Problem is there is no one around me to test it. I am not going back to the same shop that already told me that it was a bad main power supply board. Any other suggestions?

I had the same problem, no picture, contacted Philips who put me on to NESN (0845 610 4105) for local agent, they diognosed a falty "Inverter Board" all costs will be £365as the set is only 18 months old Philips are looking into some compensation towards the costs. I await there reply. Looking at several web sites worldwide this seems to be a problem with this set between 12 & 24 months old.
