I have this TV and for few months it has started given me problem. When I switch it on I get a horizontal line with sound. If I lift or press the corner of the circuit board a little bit, the full picture with sound appears. The picture is more stable when I lift the corner at the scart side rather than pressing it. If I leave it at that, the picture remains but unstable. Even walking on the carpet makes it unstable.
I took out the Tuner and I did not find any dry or crack solder joints even with 3.5 X Loop. I have examined the board under the light with the same magnification and re soldered many joints which I thought suspicious. Still the symptom persist.
I would like to know if anyone knows a specific cause and cure of it. Thanks.
