Start simple by using different cables, whether they be HDMI, VGA or standard COAX cables. They could be losing the connection. Also, it's possible the power supply is wearing out and it gets too hot. You might want to simply try some spray air duster type thing to clear out any dust that can make it hot.
Hello
Your flat panel TVs picture tube base board has soldering loose contact with it. Just unplug your TV from AC mains socket, and open it. Pull out the picture tube base card from the picture tube neck. Pull it out straight, no shake must be there, as it will damage its connecting pins.
Normally, loose sodering are very difficult to loacate, as they will be quite micrscopic in size. Just resolder all the suspected loose sodering point on that board, by applying a little more solder. This will solve your TVs problem. OK.
your dose not use lamp, it is a crt driven TV . One of com problems for that model was loose connection on one of the yokes. When that normaly happens , there is a sudden flash and screen gose dark and sometimes it can flash back if not you get red light blinks. If you you know where the yokes are at check little small board . A small mirror will come in handy, access from front of TV. adios ... john
