I have had my hs10 pj for 9 months with 250 hours on lamp. Normally I unplug the pj from the mains when not in use,and plug it into the mains when needed. But recently on 4 different occassions the pj has failed to start up, when I have plugged it into the mains and switched it on. the yellow led (lamp/cover) flashes and if I unplug from the mains and plug back in it then starts up. I think the problem is caused if I leave the mains on for a few minutes before pressing the on button, but if I press the start button as soon as I have plugged it into the mains, the pj starts up ok. My question is should I contact Sony and have the problem looked at by them bearing in mind my 1 year guarantee will soon end, or do i just ignore it because, I think others who have also had this problem, have not found a solution. Any suggestions please.
