My TV, a 21 year old Grundig is beginning to play up. O.K. I can hear you all say "Get rid of it and come into the 21 st. century". Well I probably will do that eventually. I am not sure that what is happening is terminal though, and it has a smashing picture. Every so often the picture disappears to be replaced with a horozontal whitish line across the middle of a blank screen screen. This line stays there for a few seconds, sometimes a few minutes, and then the picture reappears. It happens at random, sometimes once a night or sometimes two. Is this effect indicative of tube failure or some other electronic component? The sound is unaffected throughout which really isn't surprising. Please advise.
This is know as Frame Collapse, it's usually a dry joint that needs re soldering or a capacity that needs changing, it's not a big job either way so ask for a estimate, we charge £35, inc call out. ( nothing up with the tube )
