Ok now you can go ahead with your fuse story...  |
Rat.
Okay, this took place in the early 80s on a Zenith System 3 (which doesn't really fit this section). I was on a house call when I found the 4A slow blow fuse blown on the 9-160 power/sweep/HV module. Zenith guys know that when the 160 had a blown fuse, you swapped the module out - changing the fuse was a waste of time.
Meanwhile, the customer is all over my shoulder saying it must be the fuse - that's all it needs. I told him that a blown fuse in this board meant problems, but he wasn't convinced, so I found the biggest fuse I could find in my tool box which was an 8 amp IIRC.
I snapped the fuse in the holder, plugged the TV in, and had the customer get down near the fuse and keep a *real* close eye on it so he could tell me if it blew. I walked around the front of the TV and pushed the power button. I could hear the telltale soft pop of a blown fuse and the silhouette of the guy against the wall for a split second.
I asked him if the fuse blew. He came out from behind the TV wide-eyed. I'm sure he saw that flash every time he blinked for the next half hour.
He didn't question the replacement 9-160 board after that.
