Did you try using the crop/zoom function of your DTV box? |

My DTV doesn't seem to have that feature. Neither would the old video game, of course. Are you saying I should ignore the problem and just adjust the video source?

1976 RCA picture problem
Quote:
Not saying to ignore anything, just to be sure you identify the actual cause so you're not barking up the wrong tree. You really need to find some video source that outputs 4:3 format and connect that to your set. Then, you can tell with more certainty if your set is not displaying the signal correctly. It would be ideal if you have another 4:3 TV so that you can use process of elimination to determine what the culprit is. Incidentally, what is the make & model of your DTV converter box? |

For gosh sake, three pages and no one has said how to determine if the small picture is the TV or the source? Just turn up the brightness control, and the whole raster will get bright. If the sides, top and bottom are still pure black, it's the TV raster being too small. If light appears in the black areas, then the problem is the source.

Thanks for your input, everyone. I took it to a skeptical repair shop for a diagnostic. He seemed more interested in getting the $20 fee, but we'll see if he has anything to say about the problem.

Update: The electronics repair guy called me and said it appears to be a problem with the "flyback" ... this is not a part he can source. What steps should I take now? Is this a part for which I could just pull the parts number and order one on ebay? How would I know a good one from a bad one?

Your flyback is fine if you have a picture. It is about the same as saying the CRT is going on a set with a good CRT that you don't want to service...He just wants you to give up on it after paying the fee, without him doing any work.

You can drive 100 miles north and pick up 2 really nice 19 or 20" color table models that work perfect, free for the hauling. Either that or check Craig's list for sets nearer to you. |

Earlier in the thread, people suggested the issues could be low B+, and a dirty tuner.
Both of those issues are consistent with the symptoms, and my experience repairing old TV sets. I would never say never, but it seems fairly/extremely unlikely that any of your issues are at all flyback related. Maybe post an ad in the classified section looking for a local tech or forum member to have a look at it? I think a decent tech or even hobbyist could have this diagnosed properly quite quickly. My only wonder is why someone from Chicago would want an RCA, and not a Zenith or an Admiral |

Almost impossible the FBT is bad. Did you check for cracks on
the main board ? This set is quite simple, dosnt even have a regulator. if the board is OK I can give you a few voltages to check & maybe find the problem. Reason for diagnosis can be many. I could go into that if you wish. Reason for the $20 is 95% of sets not worth repair are abandoned. Then HE has to pay to recycle it. thats $10 - $30 around here. Lastly how many $20 bills do you need to make $50 K a year after 15% SS tax plus state & fed taxes. You would have to gross at least $70 K. And that dont cover shop expenses. 73 Zeno LFOD ! |

Here the disposal fee is collected up front, when you buy a new TV, so old ones are taken for free disposal. That would be extremely annoying for a tech to be stuck with disposal costs.

I picked up my tv from the repair guy. I said, "So, you think it's the flyback?"
He said, "Oh, I know it is! There's sparks shooting out the side of that thing... and it's an old style one too." I know many here said I should not have a picture at all if the flyback was the problem. Images attached below. Screen images in original post. Any thoughts?

I see nothing wrong with the fly. ANY non-plastic encapsulated fly from the oldest to the last generation(like that) even bran new and in absolutely perfect condition will arc from the tire to any metal object placed too close.... that is why older sets placed them in carefully laid out boxes to keep things from entering the arcing radius....

The flyback is bad. If you look in the left bottom corner in the photos you will see the core is cracked.
