It looks like my remote is similar and unfortunately it works in the same way. That means not working.
Anyone found what is broken?

It never actually did work, but because i bought it in Iraq, i would have had to take it back there to get a refund or something.. which wasn't an option..

Presumably  "not working" means something like "the led is not glowing"

Did you build this or is it something you removed from a commercial product? It is suspiciously emptier than it could be...many "missing" components, although it doesn't necessarily mean much, since component counts can be modified by performance of circuits or differences in models.


If you built it, check to ensure that all your components were properly installed
Also, check each solder connection to ensure that there are no "cold junction" solder junctions.

In either case:


1) Is voltage reaching the board?

test for voltage at the points where the two feed wires attach to the PCB.

NO?>broken wire or bad battery/batteryholder

YES?> continue

2) trace the circuit from the red wire to the switch.

With the switch set to the ON positions, is there voltage between the point on the PCB where black wire connects to the PCB ( COM) and the circuit just "downstream" of the switch?

NO?> bad switch

YES?>  Insufficient data to continue debug. Aborted
