Not famillar with Hitachi unique faults because our shop specialize in
RCA, Samsung, etc but do service a oddball brand once in awhile. Since when I replaced D744 (12V zener) TV worked for few minutes then cuts out. Now relay will just make CLICK-CLICK as soon as standby power SMPS kicks in, here's the kicker, standby power SMPS actually shut down. Had to reset by pulling plug and as soon as plug is in, relay clicked twice, horizontal didn't even try to start. Try again, same story. Oh yes, replaced several small capacitors. Thanks & cheers, Wizard |

Possibly the zener you installed failed or incorrect value?
