If the screen gets really bright then shuts off its going into protection shutdown. Could be a bad or shorted green tube. Or your missing the drive voltage from the sweep supply that suppys b+ to the screen transistors or the High voltage block. This is a hard thing to track down without monitoring points in the curcuit. If you troubleshot electronics i would start with measureing the screen voltage first. If thats ok then i would then monitor the HV shutdown triger point to see if the problem lies from the HV going to high and if its shutting down from an overload then test the green crt. if thats good disconnect the green 2nd anode lead from the HV distribution block to see if its in the green tube or from the High voltage. Any way your gonna need a service manual and a schematic and you can order that from sams photo fact.com ood Luck

Horizontal white lines 27A43.

You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

Those are called retrace lines and they are the result of the blanking pulse not having the desired effect. This could denote a problem in the Horizontal section of the TV. In this case the green gun is not being turned off as it goes back to the left side of the screen.
