Instead of hundreds on a new control board, I used about $1 in parts (if that) from my junk box and about 20m to do the fix. Even if you don't have the equipment, it might be worth bringing the control board and a printout of the repair instructions to a repair shop and have them pop on a resistor.
Thanks for the input, that post has been seen and mentioned several times in the past. Yours is the first response and with positive results as well. Thanks Again
