Subject: Re: More on my flickering DEC monitor
I'm curious what a leakage and corrsion looks like with flux
left on the circuit board?
So am I, for future reference......
good, has to dug out. I do sometimes on the TV &
monitors at
work. I work for a electronic repair shop daily.
You're a handy man to have about then :)
This is called fractured joints, fix them. Before
soldering,
get a pink eraser or rod eraser that can take off oxidization
on old penny, give it a few scrubs over those suspect joints
I just sucked off the old solder and put new on - it's nice and shiny now.
Remove the CRT tin cover, you will see some cracked
rings on many
parts too. Ditto to any hot parts, heavy parts and/or large pins.
Yup, I went over everything that was dull and tired looking. The only real
cracks were the ones I photographed. Having gone over the PSU and logic
boards I got it all back together last night and it's sitting next to me now
running my second desktop. So far it's producing a much better picture than
the the Compaq monitor I'm looking at now.....which is 4 years younger.
it is junky or too little estimate, do good job but no
clean
up. Those excess solder in that photos is sign of a rushed,
lazy tech.
So it's been repaired before then.....
What kind of digital camera taken those outstanding
photos
that showed those cracked rings in those solder side joints?
'tis a 2 year old Fuji 6800, possibly the last half decent camera they
produced before coming up with the awful A601. Works best on a tripod though
- those pix were hand held so I'm surprised they came out so well!
Cheers
