I do have a waveform at the collector at the correct frequency but seems to be distorted and too low.
since it is not easy to reach the components on the board, I am afraid that I will eventually break the PCB and the copper lines.
would someone happen to know if there is a common problem on all these sets. I find it strange to have the same symptoms on all of them. does the flyback transformer go on these sets, I have no means of measuring the transformer.
I would really love to have at least one of them going.
I thank you in advance for your help and advice.

I don't get into many of solid state sets but if they are old flybacks do go bad and humidity could be a cause along with resistors. Check resistor values around the horizontal transistor.
