Subject: [TechAssist] CTC186A-No Sound



 >> Hello!  I am working on this CTC186A that has no sound.  There is a hiss

coming out of the speaker.  I have done some research and have read that I
should re-initiate the eeprom.  How do I do that?  Any info appreciated.

 >> Thanks
To reinitialize the EPROM you need a RCA Chipper Check setup.

Or you can just order a new EPROM & install.
