Flashing Screen when earmed up ?

It's likely a loose solder connection that acts up after a short warm up period or defective capacitors on one of the circuit boards.

if their is a sound but black screen the cause could be a bad lamp.

I would suggest you contact Hitachi customer service to see if their database has this as a known issue in this set.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Hope this helps

Thought these additional details might help as we are having a similar problem.

When the washer is turned on we get a blank screen, then after a bit we see the display flash. After sometime flashing then we see it go to normal and we can run it. It is as almost as if it need to warm up...

We can get the display to show faster, by playing with the knob. However, the machine still needs time before we can use it.

Any ideas?

Thanks in advance.
