If you would like to improve the brightness of the display this how you =
can do it. On the inverter board, there is an 18 OHM 1 Watt resister. =
( R3502 ). Replace this resister with either two 10 Ohm 1/2 Watt =
resisters, in parallel, or one 5 Ohm 1 Watt resister. The result will =
be as follows.. Hi will be brighter, but not too bright. A more =
pleasant looking display. DO NOT jumper the resister as you can cause =
components to fail on the display board from over heating. Note if you =
use a single 1 watt resister, the leads will be too large for the holes, =
suggest that you cut out the old resister and solder the new resister to =
the leads. Otherwise you will have to enlarge the holes. The resisters =
that I used were radioshack 10 ohm's. Which fit nicely.. Once the =
display is warmed up I can now easily see it across the room as well in =
sunlight conditions. =20
TIPs: If you ever have a problem with the display, check these items =
first. A. R3502 B. Fuse F3501 C. Thermo fuse F3502. D. Make sure =
there is 13v at pin 2 of J3501, if not, the problem is on the display =
board.
This should work on the MP & Field.. If some one has the schematics =
copied of the field scanned into the computer, please Email them to me =
......=20
The original resister drops the 13V dc down to about 10V dc. The new =
resisters will only drop the voltage to about 12V dc.... There are NO =
heating issues from this mod. ONLY a much better display...
I make NO guarantee with this mod, do it at your own risk.. =20
