FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.


Cost effective to repair or should it be junked?

Classic indicator that the picture tube is 'showing its age.'

Three ways to 'temporarily' fix - listed in descending order of cheapness and ease.

1) Adjust G2 (Screen) control;
2) Obtain a CRT Tester/Rejuvenator and 'TRY' to restore emissions so that they are better balanced.
3) Obtain a 'GOOD' replacement CRT (Used or Rebuilt or NEW) and change it out.
