After you have the theory down do this if you havnt yet.
We will start with tube sets.
1) fix a few AA5 radios & learn the block diagram of a simple AM radio.
2) fix a few B&W sets. The BEST IMHO is Zenith 19" built between @1960 & 1965. They are usually metal cabinet sets & hand wired. You can abuse
them & it wont kill them. When found they dont have multiple problems
and often a like new CRT. As with radios learn the added stages, its
almost the same as a radio.
Color & solid state (SS) TV's
First remember you NEED a good B&W set to have a good color TV !
As before learn the new blocks, the old ones are the same. Best starters
are Zenith again. Look for Chromacolor sets from the mid 70's. They came
in 17, 19, 23, & 25 inch. All are near the same for abt 10 yrs. Almost
most parts can still be found & they almost always still have life left !
Newer sets after @1980 can become very complex with crazy startup & HV
shutdown circuits. Add to that tuning methods & that can be a challenge !
Thats when the fun begins
