Relay may not be for ON/OFF but degausing. They act different.
Yes its worth nothing but if you like it & it ran good give it a whirl.
My memory is bad after the 80's & my duties changed so take this with a grain of salt.
1) there is a small 'litic cap in front of the FBT. Caused video problems.
2) In the primary of power supply there are 2 small 'lytics that kill the set.
3) pull both boards & go over them for cold joints real good. You will find
some. Hopefuly one is the problem.
The set is in Sams 2921. I will see if I got it. Beyond the above you will
need it. DO NOT buy it from Sams. Too much $$ for a crappy PDF or
Xerox copy you cant read.
