Snapping sounds usually are associated with HV. Either there is a crack in the flyback casing, bad connections in the flyback, bad connection between the black wire coming off the crt degausing field going to the crt neck board, bad connection on the HOT, bad HOT, or alot of dust and debris shorting something out, and of course something wet. Start there, and you could try pulling the CRT neck board, the standby light will keep flashing, but there could be a short in the crt.. I know alot of this sounds far fetched, but the B+ will shutdown sending it to standby, thats why the pic was going out and coming back on. These sets seem to be hard on the HOT although. I would turn the board over and start checking solder connections.
