I am trying to troubleshoot a dead paper shredder. It is a rather beefy looking thing from Staples. Big motor. It will not power up. None of the LEDs on the panel come on. I checked the simple things like power cord and fuse and no problems there.
Looking at the main board, it is a super cheap design. It has no transformer, just resistors, a few electrolytic caps (zckj or something like that -- a known bad brand) and four diodes. Then there are a couple of relays to control the motor. The board also has an 8-bit Samsung microcontroller on it and a couple of polyester or ceramic capacitors. That's pretty much it. I was going to start by replacing the 5 electrolytic capacitors with high quality ones and see what happens since it's only a couple of $ to do that.
Any other ideas on what to check? Thanks!!
