Question about JVC AV-27F702 27" TV

JVC 32" flat screen I Art AV27F702

Please Help! There are several rows of dash like horizontal white lines at the top of the tv. Some of the lines are steady and some flicker? Sometimes there are more rows than other times. At first they were only there sometimes but now they are there all the time. What could be causing this problem? I tried all the connections as I thought maybe it was some kind of interference but to no avail. If anyone has any kind of idea, I would greatly appreciate your help. Thanking you in advance, Lady D

My 15 year old Toshiba Televisiononly shows a narrow horizontal band in the middle of the screen. Sound OK.

Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,'s can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

JVC AV-32F704 32" TV Picture is blurry - cannot read any writing on the screen

You didn't mention if you saw fine white diagonal lines running through the screen from top to bottom. If so, you likely have a shorted Picture Tube which is not usually fixable. If there are no lines seen running through the screen, then it is possible the High voltage transformer which also has a screen voltage and focus control built in that could be bad. I would expect the cost of that part to be about $100, so the repair cost total could approach that of a new set I would guess.
