Toshiba 27AF43: noisy lines on top 1/5 of screen
I have a three year old 27 inch Toshiba TV. Recently a series of about
10 lines tracks across the top of the screen when a "normal" picture is present. The only time that the lines disappear is when the broadcast pictue is in 16:9 format. I tried calling Toshiba and after waiting 10 minutes a recording told me I would have to wait another 28 minutes. My questions a (1) is there a simple remedy for this annoying problem? Thanks David |

Thanks David There is not a "simple" remedy. For an experienced tech it's simple, but not a novice. More than likely this set has a capacitor failure in the vertical output section. If you are not experienced in the repair of this type problem a call to a service company is in order. Jammy |

Many thanks to ampdoc, David and Meat Plow for your help, Before calling
in the cavalry I wanted to make sure that it was neither "simple" nor "finger trouble". David |

This is usually caused by defective capacitors in the vertical deflection
circuit. Without the proper experience, training, and set up, I would suggest you give the set out for proper service. -- JANA _____ "david walker" wrote in message news:z4YXg.136250$5R2.109038@pd7urf3no...
