I know this doesn't really fit in this forum, but I'm sure there are people who can help me here. Last night I broke the RF jack out of the back of my TV. It is a 27 inch RCA. I have 2 questions:
1. How difficult is it to replace the RF jack (I am assuming that it will be simple once I've opened the TV)
2. Where can I buy a new RF jack? Does radio shack carry them? Can I just take apart an old VCR and use the jack out of that?
Thanks to anyone who can offer me a little advice.
if you can pull apart the tv then yes it would be easy - as long as you have the right tools...
Also you should be abke to salvage spare parts from old VCR's as suggested - if not stores like radio shack / Jamco etc will carry them.
If you ARE going to open the TV, be very careful around the CRT (The large glass screen). I am not 100% sure if its built just like a PC Monitor (Suction cup-like mechanism attached to the CRT) but I do know that even if its unplugged, no matter how long, it holds a nasty charge. The capacitor has been known to hold a charge for months on end.
In short, stay away from the CRT and be very careful.
Yeah, I have it on good authority that you can get killed from that charge if you were to say, piss on an old tv, even as long as 6 years arter they were unplugged. They hold their charge.
And the only way to discharge it is using a special device. My dad used to have a friend who owned a TV reair shop, and I was there when he discharged one. He put on welders gloves and when he discharged it, it made a huge booming zap. It sounded like a thunder clap.
I also have been the victim of a large voltage discharge and let me tell you, it is not pretty. I used to work at a place that makes lighted emergeny exit signs and I was doing what is called a hi-pot test. You ground the chassis and run high voltage through it to see if it will arc across the chassis to the circuit board and cause a failure. One day my gloves were not on right, and my wrist was touching the case. Needless to say I was thrown back about 20 feet into a pallette full of chassis and I was out for a few hours. Mind you, it is really low amperage, so it wasn't nearly as bad as it could have been.
But suffice it to say, always be extremely carefull when working around any electronic item.
I found a new RF jack at radio shack and it was a snap to put in. I just screwed it into the plate and sodered it to the post that was still sticking out of the PCB. The TV is "good as new"....even "better than new", I was able to make the new RF jack much more solid and stable than the original. Thanks for all your input.
