I was watching the first LOTR and i noticed a slight redish tint to fast moving objects, only very slightly and it was for abotu 2 seconds of the movie, i then after watching it, put the 2nd LOTR about 10 mins later, about 2 hours into it in the battle scene i noticed the redish tint again, then about 5 minutes later the amp switched to stanby mode, i think it may be overheating, i mena i had it on for 5 hours at least handling the video and audio so its not anything major i hope. Im using the Marantz SR4500 with svideo switching and a digital coaxial cable running to the dvd player from the amp. I have about 15cm above it and unlimited (basically) to either side and nto so around the back of space, it recomends 20cm around all sides, i cant really have this without moving the amp out into the middle of the floor and i dont really see the need if it handled 5 hours of it fine without cutting to stanby. I havent turned it on yet again so im gonna do so now and watch LOTR the 2nd one the rest of the way through, ive left it for about 30mins now. Should i worry about this or is it normal for prolonged usage of amps? Also is the redish tint down to the heat problem or the fact im usuing cheapish cables and svideo. Im usuing profile gold cables, each costing me about £23 each for the svideo and the digital coacial, both 1m long. Thanks for any help.
