are right?

Check +12 V, +72 V line.

Check and replace IC103.

Yes

Cathode DC levels are right?

Check +72 V line.

Check and replace QR01, QR02,

QG01, QG02, QB01, QB02.

Yes

G2 voltage is right?

Check G2 wire, CRT Socket board,

and FBT.

Change CRT.

Yes

Done.

Check signal cable and connection.
