Inop 14" B&W CCTV monitor

Monitor made in China for ADT used by Lorex for 4-camera security system. Power supply inop. Has three outputs: one for TV chassis,one for the cameras and the third for another pcb I have not studied yet. Data on the plate is: Model HD14Q2144-A serial Q0305-0150B. 100-240 v, 50-60 Hz. Power supply pcb has: HGF-SF33.PCB.B, 2003-02-12, SF7.320.141B. I am sure the problem is in the power supply since none of the outputs show any voltage at all no-load.

Suggested Questions And Answer :


How to hookup audio to home security sys


Do you have audio cameras, they don't usually give you the audio cameras with a standard setup, on the back of the dvr there is a plug for audio its either a phono plug or a mic input socket, this can be used in one room or outside depending on the mic you have to buy. you then wire this up to the cctv and have to setup the sound to the camara number.

How to hook up audio


Connect a microphone and enable the audio. It should all be in the settings. Check each camera to make sure audio is enabled. Usually it is off by default.

Inop 14" B&W CCTV monitor


You are correct. The power supply (trace) is a very high voltage device. If it goes out, you will receive no power anywhere in the unit. It will most likely be cheaper just to replace the monitor.
