    Sony Trinitron Color TV KV-27S25 Problem:
    ready light blinks then TV picture comes on then it blinks
    please advise
     
  2. Sounds like the typical failing CRT...IK voltage on CRT neck board
    drops to about 0.6 VDC from over 2 VDC. Service adjustment of CRT
    screen to increase IK voltage will work initially. Sometimes a light
    CRT cathode/grid cleaning cycle will buy you some time as well, but
    the CRT is likely down to its final 6-12 months.

    The CRT is most likely failing. The proper fix, is to change the CRT, but
    this would not be feasible.
