If you have the service manual don't forget to check the + and - 28vdc pico fuses that feed the IC's. |

I have the board out right now and waiting for the ic chip
all the fuses checked good the only question I have is your saying the
convergence IC's but this set seems to only have one stk393-110 |

Recheck the pico fuses. STK393-110 is a 6 channel amp. So yes, there would only be one in this set. Usually when you unsolder the IC half of the pins fall out of the IC.  |

I have been looking for the pico fuse but I can't find them I found resistors,I found the chasis grdI also found a fuse that states its A heater im thinking it may be a thermistor I still have not been able to try and see if the voltage is present to feed the IC chip i was waiting to get the new IC before I put the board back.would you know a coponent number for the fuses  |

| Looks like it's 24 volts. R8C60 .47 ohm 2 watt protects the -24 and R8C59 is the same rating and protects the +24. Look closely at the signal board for fluid leakage also. Look good everywhere. |

I installed the convergence IC and made sure the resistors where good
when I went to turn on the TV nothing happened  I could not find any leakage of antkind on the signal board or any other boards.
I will have to start tracing back power to see which component might be at fault....I dont even have the led light on the front either ..hope I can find the solution |
