Are the sensor able to switch on the monitor, when you start rowing? The easyest would be to take your monitor to another rower and plug it in and test. It's not easy to measure whit a multimeter, but the sensor is generating about 6 uA when the magnet on the fan is passing the sensor. Row slowly an...

Do you got a multimeter?
Messure the resistans in the sensor,
Should be around 106-109 ohm.

It might be an open loop in the wire,
try to wiggel the wire from the plug and onwards...

Carl, Thanks for putting me in the right direction. The MAX1044 is changed. The keypad was cleaned from before, but I recleaned it and got all the keys working except from the on/off. Figured out that the on/off buttom had very high resistans, "shorted the bord with" 200 ohm resistor, and the on/off...

Update: Connected a spare RPM pick up sensor. When I touch this sensor with a magnet, the display works every time, pulling 2.64 mA, dropping to 0.1 mA, when it goes in to stand bye mode. The monitor would not start every time when connected to the pick up sensor on the rower. This sensor works ok w...

LCD and elasopolymer strip are cleaned...

Rev 1.7 Enhanced PM II Ser # 01/03/96 No sign of corusion. Display are dark most of the time, seems difficult to get it to work with on/off buttom. Need to row to get it started, ore replace batteries... Sometimes, the display are very dim, before it fade out after few second. (Replacing batteries) ...

Nice post,
I know this is an old post, but I have a simular problem.

MAX1044 IC don't seems to get any power when pushing on button.
Have to row to get any power on the chip...

Dark display
No battrey corusion on the bord

C10 is missing the -3 volt
