I have replaced a 50 MFD cap on the vertical board and now I have a full raster but, when I apply a signal, it still has an inch on the bottom and top.

If it truly is not scanning that area then try readjusting height and V linearity (preferably with a test pattern)....Some vert sections will scan more at a different frequency (which the vert may run at without sync signals) or without a blanking pulse from a broadcast

I have found dead 40 mfd. I do have a 47 mfd but wrong voltage. The dead cap is a cornell dublier "beaver" dry electrolytic.

If your replacement is of a higher voltage it will work fine.

Ive replaced all bad/shorted tubes except for two. The audio this thing puts out is amazing and the set has the RCA color tv cabinet smell. And red is ded.

No red at all, does the heater light on the gun for red, there are 3 . If there is Alittle red there I have something that will bring the red back.

HI. These RCA TV's tend to have broken ground connections which need soldering. Also, check the resist9rs in the color circuits. Hope this helps.

There is no hope for the CRT. It needs a new one. Can someone spare a good 21CYP22A?

I have an FBP you can have, doesn’t test the greatest but all guns come up to green on my tester. Figure out a way to get it to roll tide country?

Guess the only way is to ship it, im kinda afraid to expose larger CRT to the mail system because its way to easy to break. I wonder how much shipping is?

And don't worry, I'll pay shipping.

Greyhound doesn’t do glass picture tubes anymore, I asked. That leaves UPS (who have destroyed a rebuild CRT for me) and uShip.com, I suggest uShip.com or pony express here on the forums.
