I've accumulated quite a backlog of things I'm wanting to fix. I've got an LCD monitor that probably has a bad capacitor, an LCD projector to diagnose (it looked like a bad capacitor when I opened it, but I couldn't get into it enough at the time to confirm that), a PS3 that won't turn on, my old TI-86, and my old electric shaver.
UPDATE: My XBox 360 is now intermittently making a low humming noise, too.
UPDATE 2: My keyboard lights clearly have a bad connection; they only light up if I apply pressure near the lights.
I opened the electric shaver today and discovered that a wire had broken free of its solder; the shaver seems to be working fine now. About a year ago I opened the PS3 and wired it up to a PC power supply and it turned on. Unfortunately, the replacement power supply I bought didn't fix it and I haven't had time to diagnose the issue further. The TI-86 remains frustrating because I can't find a tool to open the thing. It has a faulty horizontal line on the screen, but to open it I have to have an unidentified screw driver type with a very long driver. It looks like a Torx 6 screw, but my bits are too thick to reach the screw through all the plastic.
Most of these were given to me broken or have been broken for a long time, so it doesn't affect me that they aren't fixed. The only thing that truly affects me is my refrigerator, which occasionally makes a loud humming noise from the back. Sadly, my experience doesn't yet encompass mechanical stuff like that.
Does anybody have thoughts what to do about the refrigerator or the TI-86? The internet doesn't know the driver type I need for the calculator, Home Depot and Lowes both said they didn't know, and the guy at Radio Shack said "Beats me, but you can melt a BIC pen tip and shove it into the screw hole so it cools to the correct shape. I used to do that with my Nintendo."
...I think I'll save that as a last resort.
