symptoms of a failing inductor?

Bredsticz · 14 May 2013 at 12:05

Hi all, I have a samsung syncmaster 2032mw monitor.

When you turn it on it comes on for 1-2 seconds then switches off again. I took it apart, presuming capacitors would be to blame but they all seem fine.

The connections on an inductor coil however look a bit iffy. Wondered what the symptoms would be for this, or where else to look on the board for a fault.

I'm still a bit of a novice with circuit boards so may not understand anything too technical. There is a resistor/ transistor next to the inductor coil (can't remember which now as I'm not looking at the board) It has orange enamel coating on top that has a slight crack in it. This is the only other thing I'v noticed on the board.

Hope this all makes sense and thanks

See if you can still see an image on the screen when it goes blank.

Could be the backlight inverter?

Get up really close with a torch and see.

Then you will know if you need a new inverter or not, as normally they are the first to go.

This is usually caused by a capacitor.

Capacitor failing, was the same issue on Samsung 226 monitor, three or four bulging capacitors, cost lest than a fiver to fix.

See if you can pick up a power board second hand and do a straight replacement, it will be more expensive but saves messing about with soldering etc and you will then know for certain if it's a capacitor issue.
