ok, i observed the 5 green leds when i plug the tv in and this is what happends. They all come on right away, then the +27 and -27 leds go off first at the same time. The rest of the leds follow. Does this help out? |

Check F903 and see if it's open. |

those +/- 27V power supplies feed the convergence circuit. You probably need to replace your convergence STKs _________________ http://riddledtv.com/repair/ |
