    Exclamation Monitor Backlight Problems

    I have a Hanns-G HW191D 19' I've had it for about a 2-3 years and now its starts to develop this annoying problem. After about 1-2 hours the back light starts flicker between full brightness and ever so slightly dimmer. I was wondering if anyone had any similar problems with LCD monitors, and how to possible solve it. I'm not scared of opening it up and fiddling around with it.

    Often it is the inverter that drives the backlight. I had a problem with one - turned out to be a capacitor on the inverter board. If you can get to it, it might be worth investigating that area.

    Yeah, 2-3 years timeframe generally equals knackered capacitors. Sometimes you can't tell from a visual inspection. I fixed an ebay "faulty" LCD like this a while - £30 for a 22" LCD; awesome.

    You will need a soldering iron, solder sucker, 60/40 rosin core solder and some small snips to cut off the new caps' legs - non-pathetic scissors will do at a pinch if you don't mind blunting them slightly. You can get caps with free delivery from Farnell.
