A TV to Fix

[stormdog]

The person I'm seeing for electrolysis had an extra TV that stopped working. I was telling her about how I love fixing electronics and she offered to give it to me! I thought it would be nice to have an LCD TV as well as a plasma because the plasma does have some issues with burn in playing certain video games.

After I got it home I looked at it and realized it's also a plasma. It *did* seem rather heavy when I picked it up...

When plugged in, it makes sounds that I think are a relay engaging, and then disengaging. Just keeps doing that repeatedly. My completely uninformed guess is it's probably a power supply issue, and thus likely bad capacitors somewhere.

Oh you've started the dreaded zapping have you?

Trust me, I can empathise! :o)

There are a number of relays in any usual TV power supply. If you keep hearing relays clicking when you turn it on, I do suspect that one of the relays has gone bad, and/or one or more of the capacitors needs replacing. (I first learned electronics by hanging out with a guy who earned his pocket money doing TV repair, to supplement his pay for working in a gas station. He was a friend of my dad's, and he found it amusing that a 12-year-old girl wanted to learn electronics. When I was a few years older, he and I dated for a while, and he taught me how to ride his motorcycle.)

Apparently I have "very well-rooted" hairs. Yay me?

Ouch.

As far as I can tell, troubleshooting in broad strokes suggests a problem with the Y-sustain board, or related Y-buffer board. That's very broad strokes, since I don't have a multimeter at the moment. Following video guidance online, I unplugged and replugged boards from the power supply board to track down the issue. I ordered replacement boards. I hope they'll fix the problem and I didn't spend an unnecessary $65 CAD...

I'm hoping I can fix it, sell it, and buy a multimeter. :)

I suspect that means you don't have ingrowing hairs or kinked roots and that IS a small advantage!

Let me know if there's anything you think I might know- you can always mail me backchannel.

Unfortunately, it has so far meant that they're harder to remove than she expects, and they require extra zaps.

Deep roots.

I had a few, but thankfully only a few. Quite a lot of follicles will require multiple blasts.

Witch-hazel gel is your friend! :o)
