PostSubject: TV Hint & Kink   May 13th 2018, 11:08 pm

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.
