This one I watched happen. I put batteries in it and it held the picture I had broadcast to it from my Blonder Tongue for about 30 seconds and then slowly went green.

Is this a capacitor issue? Any guidance would be helpful!

Generally, electrolytic capacitor symptoms dictate that the problem improves with running, not get worse. The exception are what we in the camcorder repair business used to call "fish" caps, because they stunk like low tide when they were powered up. They ooze their electrolyte out of the bottom and become conductive as they rehydrate any crap that was under or near the cap.

Open it up, exhale, and take a deep breath. If the board smells like your cat after it eats, you will need a wholesale swap of every cap on the board most likely.

We used to do tons of 8mm and mini DV (mostly Sony) that needed dozens of these changed on a board the size of a deck of cards.
