I made an earlier posting urging people not to buy the Nec1000 ht because it gave a severely distorted picture after less then 1 hour of playing. The replacement projector also had the same problem but would occur after about 2 hours. It is apparent that this is due to over heating. I had to determine this myself as niether the NEC engineers could determine the cause and the overheating light failed to activate. I can overcome the problem by putting a fan next to the projector. It is because I need to put a fan next to the projector that I can only offer a partial retraction. I find rather unstatisfactory that the fan inside the projector cannot cope (even on high speed mode!) under normal operating activities and the overheating light failed. I should point that it does give an outstanding picture arguabley the best buy under £3500. So subject to the above proviso I retract my previous posting urging people not the buy the NEC 1000HT.
