Hi all, Decided to have a little demo session this afternoon on my HT300 (not +) with the Two Towers DVD. Anyway after about an hour I noticed the fan noise was gradually increasing, it was becoming more and more high pitched. It definitely didn't sound right so I switched the unit to standby for a few minutes and then switched it on again. The noise was back but also the picture started to become very white, gradually increasingly so - this occurred both on the DVD and on my Arcam players' setup menu. Switched off again and left for several minutes, back on again and the noise had gone along with the "white effect". I tried several more times to replicate what had happened but it didn't re-appear. What I did notice was a flicker on only the top half of the screen which only happens once the pj is switched on. Also possibly worth mentioning is that the pj hasn't been used for at least several months, could it just be some sort of long overdue warm-up problem? I guess to be sure I need to watch a film through to give it a good test but wondered if any of you had any ideas or suggestions? For info: Sim2 HT300 ver. 2.13, 111 hours Arcam DV88P via component Mounted upside down in a dedicated room - could dust have got into the fan area? Any replies welcome, thanks for looking.
