Hi guys, it's my first post in LYN and hope to find some help. Hv used my panny AE300 for >3 years and logged >2.5K hours and bulb is dim. It's still OK 'cos it's in full light controlled room but what troubles me lately is the CRT pj like "burnt-in" problem, e.g. after watching 4:3 or 2.35:1 movie and back to 1.78:1 movie, I would get "burnt-in" effect of seeing the previous AR "box" appearing in dimmer light ouput. However it will recover after a movie or 2 in the same AR. Anyone knows what's the problem? Aged bulb or aged LCD panel?
Is it time to upgrade? Have tried to find excuses to upgrade (getting the CFO's approval).
I have the exact same problem as yours. My panny AE200 "burnt-in" after 1000 hours of usage. It is getting more difficult to recover now. Sometimes, the projector has to be rested for a day to get back uniform light output for 1.78:1 movie.Is it time to upgrade? Have tried to find excuses to upgrade (getting the CFO's approval).
It was due to the aged LCD panel. The aging problem of organic material in the LCD panel is the biggest weakness of LCD projector.
The latest LCD panels which are equipped on AE1000 and HC5000 are using inorganic material. Epson claimed that the new LCD panel has no more aging problem.
There is the only reason which is holding me back to upgrade to another LDC projector like TW700.
