JVC TV 27" Black line on top of screen
Hi all,
I hope someone can give some guidance. I have a 27" JVC TV Model AV-27D302. It is about 3 years old. A black line has appeared across the top of the screen. The line is about 1 - 1 1/2" thick. Under the black line is a double image - the top of the screen inverted on top of the regular picture (sorry if this sounds confusing. It is hard to describe in words!). I have looked in the manuals, but did not find anything in the troubleshooting section that helped. I looked in the back of the TV - no horizontal or vertical control buttons to adjust. I disconnected the cable line and the problem is still there, so it is not my cable signal. Any suggestions before I carry it to a service center? Thanks, Brendan |

Vertical circuit problem and a shop can take care of this for reasoable fee with one or few parts since vertical is still working but poorly. If the vertical circuit burns out, cost only increase slightly. Go ahead and find service shop. JVC is nice sets. Cheers, Wizard |

Thanks, Brendan It's nothing you can adjust or configure, one or more capacitors has failed in the vertical circuit and will need to be replaced. This is one of the least expensive repairs you can have done, so just take it to a shop or someone competent with a soldering iron and it'll be fixed. |

Wizard and James,
Thanks for the advice. I will take it to a service center, and I will post the diagnosis once it is fixed. Thanks, Brendan |
