Generally, I have no problem taking anything apart including the Dell.
Should I assume the same danger applies to LCD's as CRT monitors regarding
electric shock from the charge stored in the capacitors? If so, any safe way to
discharge them? Probably won't try a fix anytime soon, too many more pressing
tasks to do.
FYI, I'm 63 and in reference to old TV's, I remember as a child of maybe 10
years, when the TV (a relatively new technology at that time) would go in the
fritz and start rolling, usually while watching a favorite show, my dad would
frantically go to the back of the TV to "adjust the horizontal hold" -- his
words.
Apparently the really old TV's had some sort of knob on the backside you could
turn with a screw driver to the fix the problem. On the rare occasion when Dad
failed to fix it, he would call the TV repairman. They made next day house
calls
in those days;, ahh the 1950's ;0 --glen
