Question about Home Security
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.
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.
