TV screen turns dark
My 24" Sharp TV periodically turns dark. The way I get it to come back to a
normal screen is to smack it real hard on the side of the cabinet. It will then be all right for a week or two then it happens again and then I smack it again. What is your opinion of this problem, is it on its way out, and is it worth repairing. Thank you all for your help. |

Your temporary fix is called "percussive maintenance" Probably a very simple repair, but in reality also likely not worth fixing. TVs are pretty much a disposable item nowadays. |

Thank you all for your help. It is my belief that your television set has developed masochistic tendencies. It has come to enjoy being smacked by you. Thus it will continue to act up so that you will smack it some more. Throw it out NOW. No good can possibly come of this situation. |

Thank you all for your help. Most any repair is going to be $50 to $150. How old is the set? How much is a new one with better features? If the TV is fairly new would cost $500 to replace, get if fixed. If it is five years old and can be replaced by a WalMart $129 model, bang it until it dies and buy a new one. The price of the LCD models is coming down. Nice pictures on them! |

Thank you all for your help.GTO is almost certainly correct. I have been collecting "discarded" TV sets for 30 years to use for spare parts, and , in almost every case, found that if I re-soldered connections on the PC board, they would start working fine again. If you can do this, it is worth the half hour investment to have a TV that will work another 20 years or so... If you don't know what I am talking about,... then just toss it into a dumpster. It ain't worth your trouble when youcan buy another one new from Walmart for $69..... Party on, Andy |

Thank you all for your help. "Periodically" -- like once an hour? Or do you mean "sporadically" as in random and unpredictable? Does the sound go off at the same time? If you normally hear a high pitched squeal up close to the set when it's functioning normally, does this change when it goes off? If the horizontal oscillator stops, the high voltage will stop as a result. Do you hear a sharp snap when the set comes on or goes off? Does the set "bloom" (get bigger, dimmer, fuzzier) as it is failing? What's it look like just after you wrap it up the side? How long does it take to recover? And, ahem, is the wall plug solid? If you look in at the neck of the pix tube, can you see the filament glowing? |

Thank you all for your help. My TV screen turned black a month or so ago. Surprisingly, I haven't really missed it and now enjoy listening to radio and Internet radio. |
