Yes, I know it’s potentially lethal

The volume on our television has been growing progressively less responsive lately. Yesterday, the whole set shut down. It was making an admirable effort, but it was failing the critical image on the screen test. Being the cyberguy that I am, I could not just leave the thing alone, or call for a so-called “repair man”.

Televisions contain enough juice to provide a one-way ticket to the cemetery, but I was undeterred. Being a graduate of what passes for Boy Scouts in North Carolina, I’ve seen folks eat poison, chop limbs and burn down medium-sized sections of a National Park (true story). I take this as evidence that the natural consequences of risk-taking behavior happen to other people.



I cracked it open and low and behold, was able to find a spot on the main circuit board that had corroded. This section was responsible for the volume subsystem, so I was feeling pretty confident in my ace deductive reasoning. I had hoped that the problem was caused by the corrosion creating a short circuit. If this was the case, there was a chance it could be fixed by simply cleaning it. Unfortunately, no dice.

My sister-in-law gave me a swanky portable microscope for Christmas, so I whipped that out for a closer look. Some of the wiring had been completely eaten through and simply wasn’t there anymore. Electricity had been flowing through a mixture of oxidant and a steadily decreasing amount of wire. Poor little TV, it tried so hard.

Anyway, it’s dead and I’m alive so that’s the end of the story.

Dad asked me who I knew who could walk 50 miles (his latest effort to make me feel better for pulling out of the race) I replied "Certainly not a boy scout!"
Dad: "true".

Good work on the TV- I am much the same- why pay someone to tell me it can't be fixed or plug somethign in for me?

I tinkered with a CRT one time and got the shock of my life.

I'm glad that microscope saw some use. Good for you for giving the fix-it-yourself a try. Consumer electronics are becoming way too expendable.

It took me a second to figure out how you had a sister-in-law. I'm not the smartest of the bunch.

You're a brave man. I would have just hit the side of the damn thing.
