hi lads hope you can help me out on this one, the above tv when you insert the power lead the relay sounds once and the unit continually switches on/ off. you dont need to touch only hear the relay once when the power is first applied. the screen stays on for a second each time and there seems to be a large square on top left of sceen that is not black but different coloured lines.i changed the four 10v capacitors to 16v while i was in there and of course no change as the capacitors i removed were good. any if on this problem will be gratefully recieved, thanks in advance
