Was working...
2600 jr had a bad pot, replaced it, great colors now.
Got a tune up kit (caps & voltage reg)
Replaced the large cap and 2 small ones visible. Tested unit, worked great.
Opened up metal shell to get at the other 2 small caps. Replaced those. Put unit back together, turned it on... nothing! The TV gets a signal, but no audio or picture.
Any thoughts?
