I have a reason to wonder and ask. Here is what is on my mind lately for this camera which served me well when it was operational that is. You know people toss around the term CLA a lot, which either means nothing or an overhaul/ complete disassembly. The T90 is electronic so we know that the shutter magnets do fail,giving an EEE error and need "cleaning." So I understand,not my department. How about the internal flat cell battery? If that has not been touched in like 25 years does it automatically need to be replaced, and is that a tough touchy soldering job for a repair shop? How about the LCD. I hear from the grapevine that the LCD never has had to be replaced in non damage use. True? Any foam seals to be routinely looked at? Any lube points needing a touch of 'whale oil', etc? Is there any shutter calibration needed, another thought comes to mind.. And,if one has already had their T90 in for at minimum the necessary "CLA " treatment,( no new parts to be installed,) another question. For anyone still using /vice collecting on the T90.. So how much would be an average repair cost for an oldie but goodie do you think? Anybody actually go for a total 'overhaul.' If so, what was done do you recall and what did he/she hit you up? Thanks for any info, much obliged.
