Question about Televison & Video
It sounds that either the screen voltage to the G2 grid of the picture tube, or the smoothing capacitor connected to the video output supply voltage has the fault. Replace the capacitor mentioned above. The value to this capacitor will be in between 10 to 22 MFD 350V or so.

could be but there are a few checks that need to be donr first.. Try to turn down the g2 control just a bit on the flyback transformer. If no effect unsoder the blure drive transistor on the crt board If the blue is still there that means the crt is shorted and you could try to clean the elements with a crt rejuvenator and see if that helps. If the screen goes to red and green after you disconnect the blue drive transistor then you need to check the osd drivers as well as the rgb output drive from the video IC. If the blue gun in the tube shorted or leaky I have in the past and it really works a isolation transformer that plugs in to the crt socket and the other end plugs into the crt. What this does is isolate the the gun of the crt from the filiments and thats where they get shorted or leaky but for how long it will last who knows.

SOURCE: insufficient vertical height
1 it is due to electrolytic capacitor defective in vrtical output stage. 2 loose contact in vertical. 3 fault due to feedback ckt in v/stage. as per schematic diagram is concern check www.serviceinfo.com

SOURCE: RCA 24V511T Vertical problem
There is a problem with the vertical circuit. In many cases this is either poor solder connections or a defecitve vertical IC. If you can solder you should be able to fix this yourself. Please note that there are potentially dangerous high voltages present inside the set even when unplugged. Let me know if you wish to attempt the repair and I'll provide additional details and instructions.

The RCA GE sets have a problem with bad solder connections in the tuner unit which also causes numerous symptoms including poor regulation, no vertical deflection, low audio or dead set.
Pulling in from the sides is either poor regulation or a bad eeprom/solder join issue

most common vertical ic s are7840 or 78040...but ur problem is 100mfd 40v capacitor in vertical section.. change it then u will get perfect pic...have anice day..
