Our Hitachi L32A01 tv suddenly broke. It seems it doesn´t receive any signal from anything, including our tv-box and a PS3. The screen is all black and occasionally it turns blue, it looks like it´s trying to find a signal. It also seems to make a werid sound now and again. We tried unplugging everything but the power and that didnt change anything. Any help would be very appreciated;)

SOURCE: No hdmi signal

you have to take it in to a authorized service senter and update firmware sorry

The general problem with LCD type TV's is that the power supply fails. They are very sophisticated designs that are difficult to troubleshoot and generally best to just replace the module, but sometimes there is visible damage in some of the electrolytic capacitors (visibly bulged) and high voltage rated parts can be substituted.

SOURCE: Black out?!?!?

I finally got information from the repair shop. Apparently it is the upper and lower panel drive. The parts are supposedly not more than a couple hundred dollars, though I'll let you know when I get the bill. I do want to say that Hitachi was great when I called them. Even though my plasma is out of warranty by a few months, they agreed to pay for parts if I pay for labor. That just might keep me buying Hitachi products despite the issues I've had with my 2 plasmas.

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.
