I have a Magnavox plasma tv model 42MF130A/37. When I turn

Customer Question

I have a Magnavox plasma tv model 42MF130A/37. When I turn the tv on it works well for about 45 minutes, then the picture becomes unstable. If I set the input to no signal the image of a box with the words no signal appears. The upper and lower lines of the box are clear while the left and right lines as well as the words are jagged. If I turn the tv off and let it cool down the cycle will repeat. What circuit board needs to be replaced?
Thank you, Joe
