It looks like it might be a failure that is not a DIY. You should request the services of a technician, since there are a number of measurements of high voltages. If you're comfortable using a multimeter to measure voltages, resistance values, diodes and capacitors then It should be easy to troubleshoot this failure.
Let me know if you need further assistance.

    Most likely 5a picofuse blown e9 as well as cap. 707,710,711 and
    H.O.T. Should replace the voltage reg STRM
    If you have a H.V. probe, DISCHARGE
    the large filter caps to ground FIRST, they usually don't have a
    discharge path and you will shock yourself or blow
    stuff up if you dont.

    4 blinks means V-STOP
    vertical deflection has been stopped

    reasons
    1. +12V is not supplied (A board)
    2. IC561 is faulty (A board)

Hitachi has LED’s, green ‘lights’ and a red light to determine what circuit may be the problem; after removing the back of TV, bottom only, plug TV back in and observe which LED’s come on …..BUT most important which LED’s don’t come on; locate and note number, EG; DP37 and etc.

Good luck, big IRISH. Ps let me know.
