Here's a totally off topic question...

[John]

I have 6-7 year old RCA 27 inch tv. On occasion, the sound will just revert to static. I have found that unplugging the set for a few seconds, and then plugging it back in, will retsore the sound. Is there like a sound card in these sets that can be replaced? Is it worth trying to repair the set, or should I get a new one?

Sounds like my SWMBO, too!

Hey John,

Sometimes I get static from SWMBO too, but darn, if I can't find "HER" Off switch!

So, it apparently will only RESET if you unplug it? Will it reset IF you turn the power on and off with the REMOTE? As far as I know, the sound circuit is part of the main circuit board, like computers that have video and sound built into the mobo!

Perhaps you're just getting in the way of it's reception with all of that hardware in your back!!! ...had to do it!!

Shocking the circuits with a plug/unplug cycle sounds like either a loose/cold solder joint, or possibly a marginal capacitor going?

You'll want to be careful if you pull the cover off, I've heard that there are capacitors in there that keep a charge with the set OFF, and could give you a wallup of a jolt!?

27" TV's are now very commonplace and cheap, and at over $35.00 or more per hour tech fees, you're probably better off just getting a new one for a couple of hundred!

If you are good with a soldering iron you can fix it yourself..just pull the back off the set ..with this model rca made the tuner into the main chassi..the problem is the solder joints around the tuner..just resolder the ground points around the tuner and the sound problem will be fixed...the longer you let it go the worse the problem will get....like the screen will colapse verticaly and intermentant snowy picture...worse case you will have to replcae the eeprom....easy fix right now.

Here's the points that need to be soldered

I'd agree, sounds like a bad solder joint. I'f you feel brave, it may be worth a try. Stay away from the yoke on the tube, as well. It hurts. Most modern tubes have a bleeder resistor now so they discharge much quicker, but they still can give you quite a wallop.

I learned to repair TV's in a high school vocational class. One day while trying to look at the picture in a mirror while making an adjustment I reached around and caught the yoke with my (sweaty) forearm. Knocked the bejeezus outta me. Threw me up against a wall and there I sat for about 5 minutes trying to reclaim my higher brain functions.

I don't recommend it.

Redo all of the jonts circled, or just a certian color? Any special solder/flux to use?
Thanks for pic. It will sure help.

Solder all the connections thats circled...just pick you up a small roll of solder from radio shack..just make sure its for electronics..you dont want to use sorlder thats for plumbing..

John? JOHN ARE YOU ALIVE? Let us know 1) You didn't get electrocuted by the capacitors 2) If you got your problem fixed. This is real neat! JACKS OF ALL TRADES.................?
