Since C228 burned check CR210 for leakage. Also check R22?
47 ohm 3W. CR210 must be a fast diode or it will short. We used
ECG552 or NTE552.
Normally if the CRT shorts you will get the color of the shorting gun
BUT a few sets will give white screen. Fire up the set & when the
pix goes white pull the CRT socket & see if the 250V comes back.
You can also LIGHTLY tap the neck of the CRT & see if it comes & goes.
Other than that measure the voltages in Sams for clues. ( the 3 CRT
cathodes are probably very low for starters....). No reason ( except CRT )
this set cant run another 40 yrs.
