My Samsung plasma tv ps42c7hdx shows flickering mainly white but a bit green and red horizontal lines across the whole of the screen with the picture in the background (in all modes including dvds). They are worse at the top but do cover the whole screen, after a minute or so of viewing it then turns itself off and back on again when it comes back on it has no tv signal until i manually turn off and back on again then the cycle repeats. i am a complete tv and electronics novice but have done a bit of research online and after taking the back off can see a couple of possibly bad (bulging) capacitors on the psu could this be causing the lines?
