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.

D52W20 won't turn on.


Do you get the high voltage coming up? You can check for this by measuring if there's any voltage at DL231 or/and DL221 (diodes off secondary of flyback). If there is voltage momentarily then the hv is trying to come on and the Flyback is likely at fault (excessive highvoltage detected) if not then usually power supply problem is indicated - Start there - tip-use the tuner shield as ground/return

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.
