Magnavox Astro Sonic Magna Color model 1C7606

[pac.attack76]

25" Color tv doesn't turn on. suspect tube with white spot to be the reason but correct me if I'm wrong. Turntable barely turns but is complete right down to the needle and 45 rpm adapter. Tuner section and speakers work great. All for $25. Couldn't pass it up. Cabinet is a pecan finish. I could tell work had previously been done probably several years ago. some newer tubes in place and 3 older ones lying inside the cabinet. that and a couple empty tubes of contact lube or something. Model number appears to be 1C7606. Serial is 1332518. Any ideas as to what year model this is and where i should begin repairs?
