| Good, now we have to check our diodes and caps in the power supply and we should be golden. Nobody said TV repair was easy all the time. |

| Yep the Horz o/p was shorted. Was a prick to get to. Anyway so far I have replaced with new the flyback tx, horz output and IC601 in the power supply. The set still won't startup and is still making a whining sort of noise. I don't know if it's just a few caps need changing, but I'm stuck at the moment. Anything you recommend checking next? |

| Yes, you must test the horizontal output transistor any time changing a flyback becomes necessary. If shorted, replace. |

Is the horz out Ic601? (STR-S5741), or would it be Q801 (H-drive)?
It's been a few yrs since I worked on a tv. I now have a schematic of the set. I've replaced IC601, but now at turn on it make a whining noise, not a high pitch like before. Is there some caps or resistor values I should check around the IC before turning on again? |

| If indeed your flyback transformer was fried, it usually takes the horizontal output transistor with it. Did you check this as you were checking the set out? |

Sony CTV was squealing, replaced flyback tx, now the sets no go at all.
I have no schmatic and the circuit is filled with dust which is making it
difficult to service. Any suggestions to get it running? |
