I second that. One can often do more harm than good trying to modify or "repair" something that still works perfectly well. I learned that lesson years ago, when I first started in electronics, and ruined some perfectly good radios in the process. This did not carry over to televisions, however, because of the high voltage shock hazard
; the most I ever did to repair the many old TVs I had in the basement of my former home in the '70s was to replace tubes. I did replace an open fusible (sand) resistor in an old radio years ago, but that was about the only underchassis servicing I ever did on any kind of electronic equipment.
The shift from tubes to solid-state components ended my electronic-servicing days forever. I would not dream of trying to repair any of my solid-state gear today, as I am sure one needs to know special techniques to work on surface-mount technology as is found in just about everything electronic these days. I understand that one careless or even accidental (!) slip is all it takes to cause real problems on PC boards, from breaking the board to lifting printed circuit traces to causing shorts
-- and heaven only knows what else.
