Re: horizontal lines and screen bounce
You have some leaky filter caps - C2C52 = 10MFD 50 VOLT (off base of Q2C51 on signal board) also check C2P05 = 100 MFD 16 VOLT off pin #3 of IC2P01 and C2P08,C2P03 = 100 MFD 16 VOLT

Hi There,
If your picture has collapsed to just a horizontal line across the center of the screen, this indicates that your Vertical Output circuit is bad and needs to be serviced by a qualified technician. I hope this helps and thank you for using FixYa!
vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch
These sets have capacitors that will go bad, but without a good ERS meater that tests these in curcuit you could be spending a lot of time doing nothing, But the most common is to find the 9 volt reg on the signal board and change all within a 2 inches of that regulator
