As requested... pix of antenna connection to board.
Made some progress... installed my one good speaker, resoldered the antenna connection, tuned my DTV converter box to ch 3, swapped out Video board and was rewarded with a decent pix and sound.
Still much work ahead, tuning voltage is low. Although I have about -34 volts to the hot end of the tuning pot, I can't get full range. (that's why I moved the converter box to ch 3 as the tv tuner was maxed out and not quite tuning the signal on ch 4.) See pix from last night.
I still have not got supply voltage from either of the rear jacks to operate the set, I supply 5 volts to the "bat" terminal on the sound board to power the set. Likely more corroded open runs will be found... the tuner boards are plagued with corrosion. Fun project!
