My TV broke up, I looked up in YouTube and it was a common problem with that model, the backlights stopped working. I bought the replacement for like 10us and changed it myself. Still flying on that accomplishment.
See? People like you is the problem, the cause the economy is in shambles, you should have thrown that shit to the curb for the garbage truck to take it, and buy a new one
If i was doing HVAC for a living I'd get a resettable blade fuse for this task, but i got a box of fuses for a few bucks and I was able to isolate the problem after 3 guesses so I think it would have been overkill.
Probably, i think they need to get some other quotes though, that price seems pretty high for retrofitting some control systems, granted I don't know how many endpoints they are managing from this single point of failure.
