No No. the screen voltage on the horizontal output tube. Its usually around 190v. Its usually on the right side of the tube on the sams, opposite the grid which should be around -45v.

stromberg6; this is a fairly common problem on these old color sets. If there is excessive drive to the horizontal output tube or a bad capacitor, even a defective focus control causing the HV to run inefficiently it wont be able to keep up.
Kinda like if a car has a restricted exhaust it falls on its face when trying to climb a hill.
These can be difficult problems to diagnose because its half way working.

Some of the confusion with this thread is a problem thats related to the ctc16 chassis only. On the 16 there is a very thin trace on the edge of the board that fails and causes excessive drive to the output and results in lack of capacity.
