This model like most of these sets uses up to 3 mechanical relays; they are black and square (follow power cord into set) and have a history of either opening or not when in use---I have seen several where it would not shut off or turn on etc where you could tap on the relay and the set would work..
The only other reason would be a bad solder connection in the same area---tap and the set works and it is either the relay or a bad solder connection.

The click is the relay shutting off and points to where your problem is.

If you have questions comment here and I will help.

Heard a pop, tv went off, then doesnt come back on


Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

The flashing red light means that the tv is in protection mode. The tv will not turn on when the red LED is flashing. The most common problem for Hitachi are the convergence output ic's. But they useually do not cause the LED to flash. This tv does also have a problem with Q777 going bad. This will cause the LED to flash. If Q777 is bad the horizontal circuit needs to be modified. This must be done by a tech.
