Didn't really run into any issues with my consoles breaking until we got to the generations with discs (beyond the odd blowing in the cartridge trick here or there). NES, SNES, Genesis, N64, even Sega CD and Saturn all functioned and still function fairly ok today when the mood strikes me to break one out for old times sake. My Ps1 was close to breaking, but continues to work (even to this day) if I find the right angle to lean it up against the TV stand.
First console that did break beyond my ability to repair was my Ps2. Disc tray broke and I was unable to insert games into it.
My Original Xbox was next, it started basically ruining my game discs at a certain point and had to be scrapped.
Xbox 360 then Red Ringed a few times requiring sending it off.
I did not get a Ps3 until the slim and a couple price drops, so that console still works perfectly fine (and I still use it for the Blue Ray player some).
Ps4 is still alive and kicking, as well as my Wii U. All my other consoles are in a box collecting dust, but hadn't broken on me to this point.
