can someone please tell me what the hot spots are for on the AVIA disc? My Tosh. 34 HF 81 has two very mild hot spots on the right and left side of the screen. They are really very light, but can be seen on certain material, can these be fixed during calibration, or in the service mode? Overall I am very pleased with my set, but this would really help to get this unit at its best. If someone can please tell me about hot spots, I would be forever grateful!!! Tried posting this on ***************, but got no replies. Thanks..
