Your TV has some loose contact in the circuit board. Usually it occurs on the soldering of picture tube base board. After long use the soldered contact will get loose sometimes. This fault cannot be detected by normal multimeter test. The only remedy is to resolder all the suspected soldering points. You just call a tecnician for support. You can assure it whether this is the problem or not; by make a small hit my hand on the side or top of the TV set while the screen goes off. Never hit it with any hard material. Only use your palm.

No Picture after it's been on a while. Audio OK.


ok you have a vert sweep problem and yes its probably connected to in a way to the "tap and fix" problem! Seems to be n intermittant connection on the vertical out put Ic or maybe even on the rgb convergence ic?? The total loss of sweep though tells me that theres two differant problems! Maybe and intemittant connection on the vert output Ic as well as bad connections on the convergence ic??.
