[Coco] An interesting computer repair story

[Mark Marlette]

Not singling you out here but this is the problem with society today....It is easier to just throw it out and go buy new. I can't, I can't.

Robert could have done that as well, but he wanted to see what 'made it tick' and was successful. Nice job Robert. I look at it as, heck it is already broke, so what harm can I do to take a look? I can fix anything, that was evident by just getting rid of a TV from my Grandmother that past away many years ago and I fixed for her several times. I couldn't let it go and it had to be 25+ years old. It was her gift to me after she past, but eventually I had to let the old Zenith go. :)

Had a brief conversation with my son this past weekend as he commented to me 'that he isn't as smart as Dad and can't do these things'. I replied, do you think I was born with this knowledge? I work hard and spend many hours learning, the same things you could learn, if you truly wanted to. He didn't want to talk anymore about it. :) He is 27.

Electronics are electronics, just packaged differently for it's final application. What is learned in a monitor can apply to many electronic items.

I'm surprised anyone does repairs anymore. I just throw stuff in the trash and get another one, though sometimes I wish I had the time or skills to save a few things I've had to toss.
Could anyone imagine throwing a whole computer in the trash back in the day? haha no way. Now I even throw out working ones when they get too old or slow, though I often try and 
give them away.

Those 2 caps have also go to pasture in the 205bw sitting in front of me 
right now.  It is a common problem with LCD monitors that use a CCFL 
backlight.  There are no brands immune to that.
