Help with my TV!
I have a Tv given to me from my parents when they got a big screen. It
is an RCA I think. It is a "CabinentTV" for lack of a better term. It is my main TV in the living room. Even since my parents had it, when watching "over air" channels, especially 2 and 4 all of a sudden the picture goes out or gets week and there is a terible "shrieking". I can jiggle the coax in the back and make it go away but it does it again. A year or two ago I took the back off and my guess is it is something in the coax connection on the tv itself. How would I go about diagnosing and repairing this? |
stryped:
Do not continue to operate the television with this problem..... get it to a repair shop and have it fixed right away. If you wait and try to nurse this along it will get worse to the point that the resulting repair will be much more expensive. Right now, based on the limited information that you posted I would guess that this is the "common" CTC 175, 185, 187 etc...chassis problem with on-board tuner ground solder connections. This is not a repair for the novice, take it to a shop for at the very least a repair cost estimate so you can make an intelligent repair decision with facts instead of internet guesses. More than likely at this point the repair will be fairly economical unless you wait too long or try to perform a buggered up home repair attempt. While you don't have to be a rocket scientist to perform this repair, it does require the proper knowledge, experience, tools, procedure, etc. -- Best Regards, Daniel Sofie Electronics Supply & Repair - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - wrote in message ups.com...

This TV has been doinghtis for years and was given to me. I would not
mind taking it to a shop but it is very heavy and my wife is expecting a baby any day now. Is there a way I can "attempt" to do this at home? What exactly is the problem? I will have to get the numbers tomorrow. For some reason it only does it on over the air channels that are not really strong. Strong signal channels and satelite do not cause the problem. |
What are the Magic Numbers please.?

You seem to have diagnosed it pretty well yourself, wiggling the coax fixes it, likely if you open it up you'll be able to see cracked soldering that your wiggling is effecting, this is a good beginner TV repair project, just read up on the safety stuff in the FAQ first. |
Be advised, if it is an RCA with the imbedded (On Board Tuner) you best read
all the info at the "repairfaq" site before even attempting to do this. Cheers. As posted, need the actual CTC number and at least the Model number to give really qualified answers.

I wouldn't recommend repairing it yourself, especially if you have no experience soldering and/or if the set uses an inline tuner module which was known to develop solder joint cracks for the tuner grounds. But, whether or not this set has an inline tuner or not depends on the chassis number, which is followed by a CTC prefix. This important number is printed on the lower right hand corner of the rear label for the television while the lower left hand corner has the model number of the set printed on the same label. If the set, according to its CTC number, has an inline tuner module, it is highly recommended that you call a reputable repair professional and ask if they can perform an in-house repair. Continued use of a Thomson set with bad solder ground connections in the inline tuner module with chassis so equipped with it can eventually damage the system control EEPROM, which will require a much more extensive and expensive repair to fix provided that parts are even still available for it. - Reinhart |

The typical problems I read do not seem like my problem. The picture
just "cuts out" and there is loud screetching. Flipping the channel back and forth sometimes fixes it. Wiggleing the coax sometimes fixes it. Seems like it only does it on the weak channels. @ and 4 the most. Satelite or vcr is fine. |
The numbers I got last night a
Model # G35830WK Chasis # CTC169JS6 Does that help? Sure it helps now we know what you have... Most probabaly the Tuner ,if you feel up to it remove the Tuner pull off the shields and resolder the ground points then reinstall. Done many.. kip |
How hard is it? Do the problems I have dictate this is what it is? I
have never soldered a board before. I have an electrician at work that is good at it though. Could I just buy a replacement tuner and pop it in? |
Could I just buy a replacement tuner and pop it in?
Yes you can... kip |

Can I not buy a new tuner?
How hard is it to take out the board if I was to take it to a repair shop to resolder? |
Stop using the onboard tuner and start using the VCR's tuner, since you've
already got it connected via RCA cables...won't cost a dime. |

Will the new tuner eventually have the same problem as the old? How do I determine this is my problem? Have somebody experienced look at it, if you've never soldered before you're just asking to have to buy a new TV if you try to save money and fix it yourself. |
wrote in message oups.com... Can I not buy a new tuner? Yes but you'll still have to solder it so what's the point? How hard is it to take out the board if I was to take it to a repair shop to resolder? Depends on what you consider hard. If you can disconnect a bunch of connectors and remove some screws while remembering where it all goes then yes. |

You can usually remove and reinstall the chassis without any soldering, but as someone else said, you still may have a hard time finding a shop to fix it, at the very least they likely won't give you any sort of warranty. |

Your are taling about the whole chasis, not the tuner, right?

give it up.... and take it to a repair shop.

The 169 tuner will not cause collateral damage to the chassis that the later models will John Del Wolcott, CT It's bad advice in general though to ignore a problem of any sort and keep using something, breeds bad habbits that are hard to kick. |
