Default TV shows stripes/lines at the top of the screen

Thanks a lot for the answer. Sorry for not posting the model because I did
not think it was very important just because it is a general problem. I
spent all night reading tv problems and found similar problem with the same
answer. I was wondering where can I get Service Manual for Panasonic
CT-24SL14J or just a schematic to find bad capacitor in the vertical
deflection? I checked IC yesterday but I couldn't find a bad capacitor by
an eye. Regarding safety I do understand it is very dangerous to put your
fingers inside of the tv because of the High Voltage unless your discharge
capacitors or follow safety code. I learned my lesson a long time ago. I
do know what I'm doing and it is not the first time. I also understand that
I don't have enough experience but again it is all about learning.

Hello!
I have Panasonic TV about 1 year old. It was working great til a few
weeks
ago, now it shows stripes/lines at the top of the screen that used to
get
better after tv was getting warm. Now I got more stripes/lines at the
top of
the screen and they don't dissapear even when tv gets warm. I removed
the tv
rear cover and found only 2 knobs for Focus and Screen and they won't
solve
the problem. I tried to adjust Var Resistor and again nothing. What can
I
do? What should I check for? Please help.

Thanks,

"What should I check for?" The nearest servicer in the Yellow Pages and
ask them what they'd charge to correct this. If the first and only
thing you try is to turn things that move to repair this, then guiding
you to the probable circuit would most likely turn the tv into dumpster
fodder. That's a nice product. Spend a little and get it fixed right.

The problem is likely a bad capacitor in the vertical deflection output.

But I agree - get it fixed by a professional and DON'T touch any of the
internal adjustments! This is a circuit failure.
