I fixed my first LCD computer monitor

[Spinning Head]

I think Dell monitors may have a general quality problem. Excluding laptops, the Dell monitor we purchased from Fry's in August of 2012 is the only flat panel display in the house. Tonight it just went black after being on for about a half hour. No power light, nothing. Tried replacing the power cord, still dead. Left unplugged about 5 minutes and yanked the video cable and it came back to life after plugging back in. In our house CRT monitors and TVs seem to hold up a lot better.
