The whole picture is a thin horizontal line. I can tap the TV and the whole picture will come back but them goes away. after about 20 minutes the tv seems to be fine. Is it worth getting fixed? I am pretty handy can I fix it myself?

Re: thin horizontal line
Defective components in vertical deflection and output circuit inclusive of vertical output device, coupling capacitors, and yoke connectors. Passive devices such as electrolytic capacitors, coils, and resistors to/from power supply circuits. If your tele is more than 10 years old dump it and get a newer product. $100 USD is a fair price to diagnose and attempt service, depending on age and configuration. Older products may not have replacment
parts available at any repair cost.
There may be a pot for adjusting the vertical size. If so, it may be dirty. If you can find it, try adjusting it which could clean it. BE CAREFUL -voltages are very high.
Thats almost definately bad solder connection. look at solder joints for cracks around teh lead.
better yet, suck outold solder and put in new on any connections that have anything larger than a standard resistor lead.
yoke plugs, tuner, etc

Turn the TV off and unplug it from the wall and also unplug everything that is connected to your TV for about 1 minute and plug everything back in again. There could some thing wrong with the power supply or a problem with the t conn board here.
The t con board or LCD panel of the tv is faulty. Can confirm by replacing the t con board. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
This sounds like a loose solder joint, or overheated component. I know this may sound like a **** question, but have you tried tapping the TV to see if it goes away? If it does, you will need a tech to re solder the loose component. I have also seen this type of line and color bleed problem, believe it or not from poor cabling or loose connections.
All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If no reciept then call 1-800-SAMSUNG.
Sounds like something is getting hot causing voltage loss or drive pulse loss to the vertical IC. Maybe you have a bad solder joint. Try tapping the circuit board around the vertical section. A capacitor could be heating and opening up.
Also you might try using circuit cooler spray and make the problem show up.
the whole picture is a thin horizontal line. Started yesterday. I turned it off and unplugged the television, waited a few minutes, turned it back on and the entire picture was there as it should be. Came home today and it's doing it again. What's wrong?
same problem, can unplug tv for a few minutes turns back on then i get horizontal line after awhile
