I replaced the 555 last night still same thing. I cleaned and re
soldered and cleaned all the solder points. I also noticed that when I
point a remote at the rear IR detector the right led lights. (It should
it's connected to the right side) BUT when I point the remote to either
front IR detector both leds light. (I tried shielding the oposite IE
and both LEDs still light)
Like I said the edge detector board works in Leah's mini- sumo.
I'm all out of things to try. HELP!
Grant or Dave you out there?
Thanks for all the help. If you have a sugestion let me know. (even if
you think I may have tried your idea all ready)
