Swann DVR system, model H264 started giving me issues. First issue started with it unable to format the hard disk drive. System would freeze up and require it to be un-plugged to resume function.
Then it started to display a message and only this message "incompatible video signal" followed by a blank screen. Nothing else worked.
Finally it would not boot up at all anymore. Replacing this capacitor repaired my machine fully. I actually even think the image it displays is brighter than before. Hope this helps someone else out.
