Minnie I have here a tip for the chassis ctc 175-76-77-87 about the eeprom no audio ,since they say when it come up to a no sound situation on the ctc 185 chassis to fallow the ctc175-76-77-87 the same troubeshoot technics,
the tip is,.With the AC desconnected from the chassis, wick out pin 8 of the eeprom,use a pick to short the pin to the Pad to temporarily apply B+ to the eeprom. Plug the tv in and turn it on, and then remove the pick to allow pin 8 to float free of the Pad.Use the menu function to sellect the speaker on/off feature and turn the speakers back on. Finally unplug the tv and resolder the pin.
Ok there are some stuff i don't understand for exemple. Use a PICK is this same as a tool? also to the PAD what in electronic terms is PAD ?in the end it says resoder the pin, any help in understanding this points is wellcome. |
