Long story short, saw a cheap listing in the local classifieds section for a T90 and a Canon FD 200mm F2.8. I bought it mainly for the glass which turned out to be a turd that needs cleaning, but then I had a look at the T90, put in some batteries and fired it. Seemed to work, but then after a few clicks i got the EEEE error and it would not fire, took out the batteries and put them in again and got it to fire once more before the same EEEE, this process could be repeated predictably. Batteries out and in again, fire, then EEE. Tried googling a bit and found suggestions about bumping it and whatnot, but it didn't seem to do anything so after a while of doing amateurish testing I just put it away in the hoard of other faulty cameras, then fast forward a couple of months and i decided to take a look at it again and whaddaya know.. it now fires every single time and without issue.

False alarm, it fucked itself again. Put on a lens and started firing in program mode in a slow shutter speed and it decided that it didn't want to lay game anymore.

Putting it in bulb mode is a surefire way of getting the error. It seems to like faster shutter speeds.

Nice, a T90. I found a youtube video with someone saying that you can still send them in for a repair but that might be more pricey than you are willing to pay. You could look for service manuals and experiment, sometimes things can be fixed by cleaning.

>>4401770 You obviously didnt google it that well, these all get this when sitting unused. It's a simple fix, you just use a little magnet.

>>4401770 T90's are very nice to shoot with but they will often do this.
Reset the batteries and try again and they seem to keep going.

>>4402011 Strangely enough It does seem to be working now even on the slowest shutter speeds. I have probably fired it a couple of hundred times and not gotten the EEE error message. It is possible that the magnet somehow cleaned itself a bit after firing it a bunch of times, but I am fairly certain the problem will return.
I also found out that pressing the battery indicator button has the same effect as taking the batteries in and out so that part was redundant. It is the first time I am handling this particular type of camera.

Camera repair tech and T90 owner here. Is there any oil on the shutter blades? There is a foam seal at the bottom of the shutter that deteriorates over time. Can you verify the shutter is actually opening and closing? The problem will go away if it gets heated up enough to where the viscosity o the oil is thin enough to permit shutter blade travel.

I left it without batteries in them for a couple of hours and the EEE problem reappeared, but after firing it a few times it started working again. Shutter is opening and closing. No oil on the blades.

It doesn't like long exposures so that is a piece of the equation it seems.

Cleaned the blades gently with an alcohol wipe although they didn't seem dirty. Managed to fire off 6 consecutive 30 sec exposures without issue.

This thing works now for some reason. Didn't touch it for a few days after it started functioning properly as in no EEE and now I can even do long exposures straight from the get go with no failures. So I don't know what did it, probably just needed to be worked in a bit.
