Sentinel 21'' Security CCTV Clicks when powers on

Hard drive lights flash on and off; clicking sound hear from unit with no picture. One electrolytic capacitor is bulging and this condition has caused visible damage to the hard drive integrated circuits.

I will be taking voltage readings this week to track down the culprit in this switching power supply. Has anyone successfully resolved this problem?

Just replaced the capacitor that was blown wasn't easy to find since it blew out the bottom. C924 a 2200uf 10v capacitor replaced with a 2200uf 35v. also replace the hard drive, that was taken out cause the voltage to it rose above 30v. all working fine for the last 24hrs.

Multiple issue,power light flashes


Sounds like first loose connection on circuit board. I would first look around the relay this is what clicks. Then also the low voltage transformers. These problems are always concerns when set is moved or bumped hard. Try this first. Or it could be a heated issue.

Power clicks on and red power light flashes but no picture


The problem might come from the fuse inside was blow out. if you have a multimeter then open the rear cover. The fuse lays near the power cord. Take it out and use Ohm meter to check it connectivity. If it is no connectivity meaning the fuse was blow out. Replace a new one with the same value (Ampere and Voltage). If it does have connectivity, the problem needs technician to find out as it relates to many parts on the circuit board.

Powering up my Lacie ethernet disk 250


When I had this problem it turned out to be the power supply unit. Lacie replaced it - if you are out of warranty you can buy them for about £25 - and this solved the problem.
