If what you're describing is a Vertical Foldover ... Bad electrolytic in Vertical sweep circuit. |

This is a common problem with this model. Now there's a new problem, which may or may not be related, but first the component/rca inputs stopped working, and now the coax input has static for sound, and the screen is black. Any thoughts on what to do? _________________ Service and repair manuals custom google search engine |

If it's the same model check D541 to see if it's shorted, R541 1.8 ohm, see if it's open and change IC421, LA7832 and C424 10uf35v. |
