While troubleshooting why an older LCD TV (Viewsonic N3751w) wouldn't turn on, I noticed several capacitors on the power board were swollen. Through my friend Google, I found that on this particular power supply (FSP271-5F01), it was common for the capacitors to go bad. I found a replacement kit, ordered it, and replaced the bad capacitors. However, the TV still did not turn on.
Now here is the part I need help with, and I'm hoping this is the correct forum to ask the question in. While troubleshooting further, with the TV plugged in, I touched the voltage regulator heat-sink to see if there was heat being produced, and received a shock. Not a minor one, but a pretty decent, better than a shot of espresso type shock. I happened to be touching the metal frame at the same time.
I measured the voltage at 86v AC +/-. I measured the voltage in AC because the shock had the back and forth feel of an AC shock, versus the continuous muscle spasm of a DC shock. I am fairly certain there shouldn't be this kind of voltage present here, but as I only have a limited knowledge of circuit boards, was wondering if this is normal, and if not, where should I be looking for the bad component?
