Red streaks across my screen of my tv

your tv needs a y-load board its like a grafix card as computers have due to overheating the board components are affected this is a manufacturing fault it tends to happen with samsung aswell

possible fuse. if the red is curved or bent, if the red is straight try covering tv with blanket so the sensors get a good reading. again if the red is bent, and fuses are good..... bad convergence ic's.... local service center

The Convergence Amp IC's are bad. You should call a good TV Tech for this repair.

im assumiong you checked the tint in the menu options. if not go check it. other wise it sounds like you have a weak tube, or you do not know how to adjust the screen brightness. this is how i adjust the brightness (you dont need to touch the focus). turn the red up until your whole screen is tinted red, then do the same with the blue and the green. then go through each one and turn down just a little till your pic darkens a little. good luck

Have you tried with a new scart or htm lead?

I have the same problem the tech told me that the picture tube is bad and costly to repair or perhaps not

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?

Yes the red tube is shorted. I will post a link to the site where I work as they have an entire AV48WP30 with a bad tuner they are selling parts off of including the Tubes. they also provide free info on how to switch out the tubes as a unit which is a fairly easy job. Heres the link.
