Well I settled down last night and began watching some movies last night in my new cinema room. Everything was going great but when i started the third movie, Half way through the tubes shut down, but the fans continued to work and there was obvious power still going to the unit. When i switched standby the PJ kept trying to power up but was just making a pulsing noise and no picture. I unscewed the lid to investigate and nothing seemed to be too warm, but an led on the control unit was flashing next to processing cycle. I then disconected the unit from the power supply and left it for 15 mins. I then powered her up again and hey presto she fired up straight away and i was able to watch the end of my movie. The projector was running fine for 6 hours before the shut down. Then tonight i sat down again to watch three more movies(days off are the only time i have to catch up!) first two passed fine with no problems, but you guessed it 10 mins into movie three the very same problem reoccured. Again i disconected from the main power supply and after 15 mins she powered up straight away. I have a sneaky suspicion that she is overheating some how but i have checked all the fan and other cooling vents and all seem free from junk and working. The owner manual gives no indication that the unit will shutdown when overheating. I also remember reading that some power supplies cause thia problem because of poor soldiering when manufactured. So anyone have any ideas? The unit is ten years old and has 6077hrs on the clock.
