|
|
Hello,
I am new to tv repair but am willing to learn and extremely handy.
I have a older tv that when there is a dark scene on the picture, the screen is squiggly. I don't know the technical term yet and that is why I am here, to learn.
Can someone tell me what the cause of this may be and how I may repair it?
Here is what it looks like...

Thank you,

model number,
it is extremely hard to tell which one you have. |

Jim,
Since his video (prior to his report of a model number - which confirms) showed a set with Tuner / DVD / VHS / AUX capabilities, asking if it was affecting just one (or more) of the inputs was a fair question. |

You're absolutely right. I think I get so used to removing so many harassing comments that I think I got a little trigger happy on this one.
my apologies |

So is there a question that I need to answer to lead me to a solution? |

Your item has Tuner / DVD / VHS / AUX capabilities, I'm asking if it is affecting just one (or more) of those inputs?
Whether it ultimately leads to the solution ... who can tell at this point? |

I can tell you that it happens on the tuner, dvd, and VHS settings. I am not sure about the AUX input. |

Is there anywhere I should start looking to diagnose this issue? |

Whenever there are strange symptoms, I always pay close attention to unit's power supplies. Even a bad ground can't be ruled out. Make sure all supplies are there, within tolerance and don't have excess ripple. |
