can anyone help. convergance ic were bad stk392-560.replaced both ics same pic when turned back on. went to g board (power supply) -22 volt pico fuse blown and 1000 uf. cap bulging. replaced both and turned on set now power supply tuns off by itself. if you try to turn it back on turns off. could conv. ics have been dameged with out -22 volts when i first turned it on.
He means the connections on the convergence IC's. Each pin connection needs to be by itself. No solder connections between pins.
yes i checked the solder on the ics . this is somthing i always check before powering up.the set didnt go out until i replaced the -22 volt pico fuse on g bd. as well as 1000uf cap was bulging from the top so i replaced it to.when i repowered up set goes in to shut down with six blinks.
Double check the capacitor. Did you replace both IC's?
i re-replaced the cap and i re-replaced the stk 392 560 both of them twice. all set does now is blink six times.im going to replace the g bd. maybe smothing shorted when i took out the pico fuse and cap.the six volt line comes up before the set shuts down.so i dont know why the processor is turning the set off.any other thoughts.i did not go neer the a and b bds.just the d and g bds.
Perhaps you pulled on a plug and it is not sitting all the way down into the connector? I have seen this a dozen times if not more.
well i found the problem. the g-board went bad. i dont know why but i replaced it and set works great. thanks for the advice.
My Sony MODEL#KP-57WM500 powers up & the screen turns red, but then shuts down. Any idea what may be causing this particular issue?
