Anyone repair a TV before?

[CocheseUGA]

Here's the situation: SDTV, 27" has been cutting in and out (from clear picture to snow) for about the last four months. Lately, it's gotten seriously bad. So bad, we pulled the 13" spare from the attic, and it works fine (so the cable et al is not the problem). I was thinking of seeing if there was a loose connection from the coax to whatever was inside.

Two questions: What safety precautions should I take, and what should I be looking for? I'm 98% sure the TV is repairable, and I'd rather wait and replace the 27" flatscreen SDTV in the living room (replacing this one) in about a year than have to buy a crappier TV now to get to that point.

Thoughts?

No help on repair but what your describing sounds like a past problem my family had.
The backside of the coax connector came loose and the tv acted as you described. Someone else fixed it for us & I don't remeber what they did but I know it wasn't too difficult.

Yeah, my wife said she thought it had happened before to this TV as well.

If I can get in there safely, I'm sure it would be an easy fix. I'm just a little reluctant to get fried.

I know how to fix sound on TV, smack it really hard, but on this no help, sorry.

I ran into a problem with a Sony 32 inch that I thought was repairable, found the part online and everything. More I read though the more people warned televisions hold a lethal charge even after unplugged, nuts to that.

Do your nuts still function?

Very well, unfortunately the t.v doesn't anymore

Yes, tv's can shock you good. The capacitor will hold charge for a very long time. You could probably bring it some place to get it fixed.

I'll also put a vote down for "take it to a repair shop, the capacitors can kill you if you touch them."

Televisions tend to have a few high discharge circuits that can still be lethal to anyone poking around back there. I used to repair TVs in my high school electronics class, and the instructor took great care in using proper discharge techniques and a minimum time between that and actually working on the TVs. If you aren't very familiar with energized equipment and such, I would highly recommend leaving it to someone else who is. I've been bit countless times due to carelessness.

QFT. Same with microwaves - PLEASE do not take them apart and try to fix them. Especially if you're not skilled with reapairing electronics.

Wow, this is shocking to me. I have no skill at fixing anything (though, I've gotten lucky fixing a few VCR's), I would never have guessed that a tv could kill you if you unplugged it. Glad I never tried to fix my own before.

I probably wouldn't have messed with a microwave, only figuring if I messed up, it would start an electrical fire, and I'd rather not deal with that when microwaves are so cheap.

Lucky for you I just so happen to have a degree in TV/VCR repair, computer programming, and I'm also an electrician and animal care specialist! Thanks ICS!

Do not with repairing a TV if you have no clue. If you are not familiar of properly discharging the CRT, then you have no reason to be messing with the insides. In my electronics shop back in high school, one of the upperclassmen failed to discharge the tube properly and sent his 6' 3 / 270lbs ass flying. He was alright but visably shaken.
