hello, i hav e a 2410012LF ver-3 board. it has problems. i replaced
R14 0.5 Ohm 3 Watt
R31 18 Ohm 3 Watt
R43 0.1 Ohm 3 Watt
still not working. on the board S1 (within the black enclosure) i found what appears to be 2 photo transistors, photo diode or ir led ??? im not sure what they are . one of them was corroded and it was difficult to remove .but i dont know what it is lol. anyway wondering what it would cost to just purchase another board or have this one repaired . thank you.
