anybody know how to refocus a projection tv?

[tonydahose]

first off i realize that this site is more for computers than tv's. i have tried looking online and am having a problem trying to find an answer. if anybody here can point me in the right direction i'd appreciate it. here's the problem. i have a mitsubishi 65" projection tv. model ws65819 (that might be ABT's model # for it) it is aprox 6 years old. about a year ago the edges seemed to be getting blury. i called abt and for $165 the guy came out, opened up a little manual and with the remote refocused the tvin about 5 minutes. the warranty for the repair was 90 days...about 4 months later it started doing it again. it seems to be getting worse as time goes on. i have tried to get this manual with no luck. i got the repairman's number so i could just call him to do a side job but his cel is disconnected. i figured there might me some tech guys here that could help me out. maybe scan the individual page for my particular tv. any and all help is really appreciated. mods if this is in the wrong forum or shouldnt even be in this site please delete it and sorry for wasting your time. thanks

a full ISF calibration is $400 - $450 , no wonder he is out of business



see here for calibration tips though http://www.euras.com/repair_tips_1/Mitsubishi/WS65819/WS65819_Mitsubishi.htm

http://www.user-manuals.com/service-manual-MITSUBISHI-WS65819.html (but $15)

see also this thread as there seems to be an issue w/ these sets http://forum.ecoustics.com/bbs/messages/2/143561.html
