Does any one have a print and or trouble shooting guide they could share. I have be trying to fix this set using information from a CTC177 chassis but notice some of the I.C pinouts are different. I have changed the EPROM and have a good regulated supply. There is momentary data at the EPROM at plug in. thanks Bruce.
