The only real problem on the Marquees was a batch or so that have LVPS voltages the float up and fry the tube filaments. You can check this with a voltmeter, as well as checking the manufacturing date of the projector too.
Other mods are more performance oriented, such as MP boards, tim's fan mods, etc. Welcome improvements, but certainly not necessary in terms of the reliability of the projector. Perhaps necessary for PQ gurus though .
Originally posted by RobertV The power supply and anamorphic squeeze modifications are the most important. The power supply so you do not fry your tubes and the squeeze so you can get 16x9.
How do you determine if these mods have been done on a potential purchase, where do you get them done if they are not and about what kind of $$$$ are we looking at to get them done? (or are these the mods talked about here http://www.avsforum.com/avs-vb/showt...hreadid=209943 )
Also what about fan mods. Are these do-it-yourself type mods ( a kit you purchase or something) or a mod a tech has to do that has done them in the past. What do the fan mods cost?
The acoustic fan noise mod is available from E-Tech by sending us your lvps, usually a two-day turnaround; we test and fix the filament problem in the price of $249 in the lower 48 states, more if offshore. Look here under Tech Tips, Gray Scale to see how to measure your filament voltage and set gray scale: http://www.etechvideo.com/
