Check for leaky capacitors in the vertical section of the TV or cold solder joints.
I would also check in the power supply.
Good Luck.

Screen has gone grey and has fine horizontal lines on entire screen. Blue screen is out.


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.

About 2 inches of the top of my screen won't show. Sometimes it will turn into a line that runs through the center horizontally. If I hit it it will go back to normal except still missing the top 2 inches


hit your TV lightly on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board at some soldering joints crack develops....then due to loose contact picture becomes small in size or disappears ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears for some time............so solution is ......TV main board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again (2inch on top will also gets solved )................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer

Panasonic 32" GAOO just atarted doing this...Turn


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.

I have a KF-42E200A Sony Bravia LCD tv. Recently we had to replace the lamp. Since then a horizontal line appeared at the top of the screen and it has grown to about 3 inches now. The picture itself is...


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.

Horizontal white lines across top of TV screen


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.

Panasonic GAOO TV


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.
