hmm, if i got you right, it's better to analyze the fault first before opening the case? like in tv:s, brightness, flickering, colours etc....
as for how i've learnt, well, there is simply ONE teacher at school who knows how to teach. Then there's one teacher, who has huge acknowledge, but he speaks mumbo-jumbo all-the-time.....not wonder students dont learn! how come people would learn if they don't even understand language?. like example, he asked ''you do remember what is phase-shift right?'' and most of the class said that they've newer heard of it.....oh well, they're lazy people, that's the problem with them. they prefer to just ''hear'' but not listen. I'm probadly the only one who takes notes. But it has the downside, i'm like second teacher, and it's pretty annoying to repeat myself just because students don't ask. Why? there are no wrong questions....
Ok, i might hear bit, broud, or something. But, there are simple reason why i'm so different compared to my class. I'm 22 and they just hit 18 this year. They simply don't have that motivation, and no surprise.
To me, motivation is simple, i have that goal which i knew already way before i even went to school. When i watch these guys i wonder ''why did you came to EE class if you don't care what teacher tries to teach?'' My whole summer holiday has went totally in electronics
.
Again, i MAY be wrong, i can accept that. I've been wrong that many times that i can accept that
.
And other thing that ''angers'' me that when i go to job interview. Couple of days back, i was willing to travel about 100km each day to work. When the decision day was on, their reply was ''your knowledge and skill is marvelous, but your education isn't needed and bit wrong'' i asked how come? ''your current education is for 230v line, as we need electronics'' But i know much more of electronics than mains.....
oh well, back to school, luckily its only one or two years anymore
.
i wish there would be more teacher like you tvtech, or like others in here forum....
and sorry if i sounded like i was wining
. but that's true what i wrote....
