I've got a cheapo Chinese paper/cd/credit card shredder that I bought over a year ago. It worked perfectly until just a few weeks ago. Now I have to operate it in manual mode to shred, then switch it off. It runs constantly in Auto mode.
The only info I have on it is that it's a Model CD71, but without any name brand on it. Upon taking it apart, I see that it uses what I believe are photo-transistors because the circuit board connections are labelled as transistors and the transistors have only an E(mitter) and a C(ollector), no B(ase).
My question is: How do I troubleshoot these components? If anyone has any ideas, I am open to any suggestions. It's not a big issue, but I'd like to just know what happened with this shredder.
