Vibrating lines across top 1/3rd of tv when turned on

When I turn my tv on there are vibrating lines across the top 1/3rd of the tv. After it warms up in time they seem to go away. One technician said it was the video display board, which he said is about $280. He just looked at the picture and did not open up the tv. What would you recomend to do. The set is just 4 yrs old. I am pretty handy and if told what and where parts need to be replaced, I am confident I could do it. Please let me know your thoughts and where I could get the correct parts to fix my tv .

Your problem is the hyper board, or whats also called the scan board, not the video board. This board is right behind the input board in the back of the TV set. This is a little tricky taking this board out. There are a few tabs that hold the shielding for the onto the printed circuit board, and if your not careful, you can seriously damage the main board. If you get this hyper board out of the set, go to ptscorp.com, call them and give them the number on the shield and they will tell you if they can overhaul this board. Most of these they can and the cost is about 135 to 150 bucks. A new board, if you can find one, cost about 350 bucks or so. Just be very careful un-soldering the metal tabs at the bottom of the circuit board directly underneath the hyper board. The board itself simply plugs into the main board, but like I said before, it is held into the main board by metal tabs underneath it. Good Luck

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF

sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

TV has a line across the screen when I turn it on.

You have a vertical deflection problem ; probably a shorted vertical output IC.

Insignia 32" TV Thin line across screen 1-2" from top

The original white line problem was caused by improper adjustment of the vertical size for which there is an internal adjustment. The current problem could come from two different sources, one an adjustment again, the other from a capacitor that is losing capacitance and gaining losses; = sick.
If you are fortunate enough to have a surviving TV repair in your area, none of these problems is expensive to find or correct.
Don't be surprised to find the only TV shop operating out of a messy garage since those of us doing this kind of service are dying off and the price one can charge for labor has shrunken to the point that a real business address is too expensive to have.

Insignia 32" TV Thin line across screen 1-2" from top

This is usually caused by bad capacitors in the vertical circuit. If you have an electronics background you should be able to find the defective ones with an ESR tester .

bad caps in the vertical output and jungle IC section. Check all boards for black runs, leads near/on caps, they leak and eat the copper runs.
