Located in the power supply section of the unit. There is a pico fuse (soldered in fuse) that opens up and there is no high voltage. The second click that you hear when the set is turned on. This can be diagnosed With set unplugged, with an ohm meter with a simple continuity test. I think the pico fuse is 4 amps , I am not absolutely sure. I have seen this problem in that unit previously. There is also a convergence problem that occurs with that set. Scrivitron.

TV Want Power up

This tv have different causes for no power.
Can you tell me if any light on the chassis is off?, if so, let me know the location part number.
Common problem is IC output ( short) or convergence STKs ICs.

Hitachi 43UWX10B 43" Power Light flashes Continuously

I doubt if its the fuse. We just helped a customer with a very similiar problem. Its more likely that the convergence IC have failed and shorted out. When this happens one of the symproms is that the TV will shut down and chirp. Goto www.TvRepairKits.com and click the contact us button. They can provide you with more instructions on how to test if this is the problem.
