Having problems with your Samsung SyncMaster 940N Flat panel Monitor ?

My monitor 940n samsung syncmaster gone in black...

\015 My monitor 940N suddenly went in black. Power supply indicator (blue) is on, but the screen is totaly black. Menu buttons are not responding.\015\012Is it about capacitors again?\015

Answers :

I have just had this same problem. The problem mostlikely is a blown fuse on the inverter board. Mine was blown on the board and also a Capacitor (470nF/25V) was bad beside the Fuse.

\015\012I replaced both and monitor is working now again. After install the picture was a little grainy with little artifacts. In another post i found that the Power Supply board needs to be cleaned for unwanted residue. After that picture was fine again.

\015\012BEWARE that you need a soldering iron and a steady hand to replace these parts. If you are unfamiliar with soldering at all have an expert take a look at this. The Power boards uses 220v so DO NOT connect it to the Power when opened.

Hello,

How old is the monitor? Have you replaced the capacitors in it before? Your problem is either bad caps in the power supply or blown transistors in the inverter circuit. Email me and we should be able to get you back going.
