Having problems with your PC Desktops ?

My Medion TFT 15" LCD monitor (several years old) now just cycles when I try to turn it on (get green power light, screen comes on for an instant, then screen and green power light go off, and cycles like this about every second). It has an external power supply (AC to 12VDC 3.5A) which does read 12VDC on my voltmeter. I've tried connecting to different plugs and leaving it unplugged for awhile to no avail. I read online about a possible CCFD inverter problem causing similar symptoms. Any ideas?


Answers :

I ended up taking it to MicroCenter and their free Tech Support guy determined that the monitor was definitely bad (not the external AC adaptor). I was able to buy a relatively cheap replacement.
\015\012Incidentally, the monitor may have gone due to an electrical storm or when my PC's power supply went. At about the same time as this problem, the PC wouldn't power on... the power light would blink and I'd get clicking. The Tech Support guy checked the power supply output of one of my internal connectors and it was definitely bad. I replaced the 250W power supply with a Thermaltake 430W one (I wanted to add another drive and a couple more cards, so increasing the load) and voila "it lives again".
