Re: Flashing Power Light

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.

Can u help? tv will not come on. clicking noise and red light flashing????

the flashing sequence is a guide to the problem

2 flashes space 2 flashes to 9 flashes space 9 flashes

once we know these we can pretty much determine the problem. None are good of course! They are all faults that need a repairman to intervene. There is no magic fix!

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 and click the contact us button. They can provide you with more instructions on how to test if this is the problem.

Flashin power light - wont come on

The "green light flashing to the chirping" circuit may be defective.

Not a basic diagnosis--service literature and/or knowledge of each green light circuit will be needed.Possible shop repair.
