REVITALIZE YOUR VIDEO!
With STAR*TECH Journal's
step is to remove this carbonized material. Scrape
the stuff away with your X-acto knife, pointed
probe, small screwdriver tip. Even if it makes a
hole all the way through, all that carbon has to go.
Any thing you CAN scrape away MUST be
scraped away. Don't be afraid. Good PC board
material is sturdy and stands up to scraping with a
hobby knife. Anything that moves has to leave.

Once you clean up the board, you have to restore
the circuitry. One usual casualty of a fire is the
tracework, it just bums away. Sometimes traces are
left in mid-air. Tempting, but don't use them. Trim

Repair as much of the tracework as you can di-
rectly, in the same way as repairing a cracked
board. Some traces are best replaced by jumper
wires. Just make sure you are taking care of the
just-passin' -through stuff. That is, the trace that dis-
appeared may have gone to a transistor leg, but it
may have continued on to somewhere else, or the
component that burnt might have erased a trace
that wasn't related but had the misfortune of pass-
ing underneath. You could leave a whole section
of the board without ground if you aren't careful.

STARTING FROM SCRATCH
Worst case scenario is the board not repairable. If
a transistor goes and just bums away the board
completely, you have little alternative to building
a new board section.

4 Design Improvements to
the Industry Standard
The "Quick Release"
Ticket Dispenser
Improves serviceability
& reduces
maintenance
Sometimes the shattered portion of a broken board
is best replaced. It is not so bad as it sounds. I use
a hobbyist experimenters board to rebuild the cir-
cuit. In the example of a burnt solenoid driver tran-
"Sometimes your board
invents fire, and the results
can be pretty spectacular!"
sistor, I would mount the replacement and maybe
a couple of supporting components on a small area
of a PC board. Then I would trim the board to
size with a saw. Run jumper wires of appropriate
length back to the original board. Use your discre-
tion when mounting this new board, keep it as close
as possible. For a relatively small piece, I use two
side sticky foam to mount the work nearby or even
stuck right on the old board. Alternatively we could
drill a hole in the board and mount it with a screw
or a bracket.
"Quick Release" face plate
Dynamic, new design allows the
ticket dispenser to "quickly release"
from it's face plate on your cabinet
or ticket door, no tools needed.
Easily replace one dispenser with
another in just seconds. No tools
necessary! The new face plate
retrofits any existing Deltronic
Labs machine.
Bottom METAL ticket guide
The extended, durable ticket guide
prevents curled tickets from catching.
This kind of board damage can be pretty dramatic,
but it needn't be traumatic. A little effort, and per-
haps a bit of tedium, will restore your circuit to
operation.
Foolproof braking system
Our impressive new braking system
eliminates brake slippage, allowing
foolproof, accurate dispensing.
You don't need to pull your hair out.
If only I found that out earlier ...
Optical sensor dust cover
Eliminates dust accumulation and
increases accuracy of the ticket count.
