Look for high voltage cap like 200-250v 100uf that could be bad around flyback. Also look to see if reg. shorted, and horz. output bad.

Come on then line horizal across screen then turs off


Horizontal line (up and down) is know as horizontal collapse. This is usually located around highvoltage section of the circuit. Because this circuit depends on certian frequencies and voltage protection circuitry will shut the set down. This will need a trained tv technician to fix this and can be expensive depending on the parts needed.
