X300s shutter problem.

Recommended Posts

I have an X300s. The problem is even when i put new batteries in the

shutter will not fire and it then does nothing. If i switch it off and

back on, it looks fine the meter works but as soon as i press the

shutter release the camera is dead again. Any sugestions.

A common problem. Almost for sure capacitor C7 1s faulty. This capacitor is a Tantulum 150mfd 3.15 v . these capacitors cost about $1.20 Australian here for a 6.3v one.Tantulum type is necessary for leakage + space consideration. You access this capacitor by removing the bottom panel (4 small screws ,about 30 seconds with GOOD screwdriver).

The capacitor is directly under to one side, soldered to the flexible pc board. with care + attention to polarity etc, replace . Its a good idea to test capacitor first to confirm fault ,good readings can be taken while on board but if in doubt remove for test . The last one I did had drifted to 44mfd eg no shutter release. This camera had identical symptoms. So for about $1 and 5 minutes, fix your own.You should test and select the replacement capacitor to be spot on as some components can be poor in the tolerance area. Maybe dont take this on yourself without reasonable tool skills , tools, and a little understanding of what you may do to chips etc with a bit of static charge and the pc board is a delicate thing in relation to an overheated soldering iron.But a quick and easy job otherwise.

I checked the capasitor and sure enough it was low. I'm haveing a hard time finding another one that will fit. The smallest i can get is 16V and is twice the pysicle size. Does anyone have any idea where i can pick one up. Thanks for all your help. Jim.
