Starting off nice and easy with this one. A colleague at work is complaining that his secondary monitor is temperamental - taking a long time to power on and randomly blacking out.
Having recently joined this site I thought I'd take it home and have a look. Once apart I could see one bulging CapXon capacitor on the power board. I've also invested in the Atlas ESR70 meter which came in really handy.
This cap was 1000uf 16v - the meter showed less than half capacitance left and a high esr value as well. I also replaced the one next to it (470uf 50v) as well because it was also on the low side for capacitance. I replaced these two with Panasonic caps.
Monitor works like a treat and my colleague is mega happy. Thanks for the great posts on this site - I am learning all the time.
