Another view of the Problem Resistors
Using a FINE TIPPED soldering iron, and VERY FINE solder, simply resolder the
"Problem Resistors" back into place. Be VERY careful not to hold the iron
on too long, as you can damage the components from too much heat.
You will notice in the pictures that I have replaced one of the "Problem Resistors"
with a "regular" resistor. This is because the ORIGINAL surface mount component
resistor was lost by the owner during the removal of the unit.
These resistors are not soldered in very well, and they are subject to enough heat
that they weaken the solder joint and occasionally FALL OFF! If you find yours is
missing the SMD resistor, or the resistor is laying in your tray, it is OK to re-use
it. It is NOT DIRECTIONAL. If you lost your original, you can use a standard style
resistor. The 680's are 68 ohms. I had to replace one as pictured.
If you notice a "burn" mark on your display screen, it is OKAY!. All of them have it
and has something to do with the manufacturing process, and is not a sign of a broken
display.
The above details are by no means all inclusive.
