Take the lenses off and make sure that everything is clean under them. make sure to so one at a time and put them back on exactly how they came off. otherwise clean the mirror and look for some debris in between the screens

Small red dot in center of 53" Hitachi projection tv


hi, not good news it`s probably a burn in on your red crt (picture tube), tv has to have back completely removed, which means top and bottom covers, (carefull with the top cover it`s heavier than u think, has mirror bolted to inside), turn on tv just long enough to light up all 3 crt`s to identify the red one, turn set off & look into red lens,(may need flashlight) if you see any black specks in center of tube it`s burnt and has to be replaced, be advised u will see gnats, ect. inside but your looking for specific speck, if no visible burn mark have tv man come out, otherwise it`s very pricey, hope this helps and not crt, video-tek

Hitachi 53" rear projection is losing its picture.


If you are not experiencing any shift in colors, it sounds like the power supply is failing since this will affect all three colors.
