Servicing Samsung LED Monitor 632NW

led monitor repair










This monitor was brought to me with the complaint that it was dead. On inspection, noticed that the AC female socket had fungus attack and burnt marks due to arcing. Noticed water seepage also, probably by rains splashing through open windows. It had rusted too! Opened the set and removed the female socket. Removed the earth pin as I wanted the holding metal cover riveted to it, since the replacement available was of a different type.     samsung led monitor repair

Fixed the socket, using the old metal holding cover, and manipulating the rear pins of the new socket, and adding extra tags to solder it firmly on the PCB.     how to repair led monitor

I had to adjust the socket perfectly by keeping the back cover in place, before I soldered the metal holding cover. It was a perfect fit as you can see from the following snap.

ESR of all caps was ok.   Just touched a few dry solder on the PCB. Powered it on through a series bulb and it worked perfectly well.              how to fix led monitor

Tested it thoroughly and found it to be working well.

Another job added to my satisfaction list!
