Since we don't have a TV area, I will post this helpful hint here.
Many folks don't like working on the old tube type & solid state TV sets.
They are big, scary voltages and it's not a radio.
Well skew your thinking a bit-
Think of a TV as a radio- sort of.
It has a tuner same as a radio, just made a bit different and higher fre
It has oscillator sections- like a radio, except they are called Vert & Horiz, color, and tuner
osc. (Hey- an osc. is basically an amp with feedback- right?)
It has amplifiers-IF, Audio, Vert ,& Horiz. -
It has a power supply - like a radio
It has a high powered RF oscillator that provides the HV for the CRT.
The video ckts. are all a form of amplifier.
The color set just has a few more amp. ckts than a B&W TV has.
Not so scary now- is it?
Just get a good schematic and take your time. If you don't understand something, ask questions.
