If it's a CTC-12 clone then you will not have the same problem with the blanker tube bias effecting the HV production, that did not happen until the CTC-15. It was a backup to runaway HV if the shunt tube failed.

If it has a 1.5 meg resistor from the control grid of the HOT to the term TT on the chroma board, then you have the blanker tube bias issue.

the 12 schematic shows the same 390k resistor off pin 2 of the blanker tube just as the 15 and 16.

Ok first forget the clone crap, thats something the super elite do so they have spare parts.

Whats the model number, its going to be something like 528.555555 and it will be on the back.

It may not be a clone at all, it may be a spinoff...how about that?

We need to start with the right model number and schematic and stop telling the tv what it is.

ok the chassis dont have a number on it but could use this number from the sams which is this chassis, 528.61110 hope this helps. and as far as this bias problem i had read a thread here on karma about this resistor from pin 2 of the blanker tube to ground and yes it was said that it started with the 15 chassis but no one knew if possibly it went for the 12 unless the sams was looked at for the 12 and it shows just that resistor in the very spot from the 12 to 16 chassis and there is no 1.5 meg resistor that i found on the 12.
