33 inch Panasonic gaoo bought in 95 picture trble

try changing picture size

Either the screen voltage to picture tube is more than normal, or the video processor IC has damaged. There is an other possibility that there is no voltage at the video output card, plugged on to the neck of the picture tube. Anyway, your set need a through checkup, and the work is somewhat skilled one. Just check this site. Soemtimes you might get some details about this fault. The fault is called vertical retrace lines. Thin horizontal lines all across the screen with an inch apart. One among the posts published in the following site have details about this fault.
Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. There are more than 1250 posts to different brand TVs now. Pull up older posts there.

The Panasonic Gaoo sets were top of the line in it's day, the problem you are describing is a vertical deflection issue caused by bad solder joints and a few parts. I recommend a tv technician to fix the set.

horiz.output IC going bad,need to replace it

The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

You just need to have the lenses realigned and the red shading will go away.

REPLACE VERICAL OUTPUT IC ' LA7838

Hi

what line started? from Left to right? or from top to bottom?

Thanks!

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

Do you have to tap on the left lower side (facing the T.V) are the lines thin and white?
Has the T.V. ever turned off by itself?

This set was made in Mexico and Panasonic have HAD problems with dirty solder joints, "dry solder joints" as thay are called, expand and "open" with heat and age. Thay can "fix themself's" when the set is allowed to cool down or if you tap the joint back together. That is untill the set gets hot again and the joint expands and.........you get the picture?
Try re soldering your power supply solder joints, you MUST desolder and clean joints!
Hope this helps, sorry about the delay never been on this site untill today!
See Ya from Waterloo, Ontario CANADA.
