I have had some issues with high ESR readings in the capacitors in the scaler circuits in those units. Do you have an ESR meter to check the caps in circuit?

I have found that the power supply is usually good, it's the other boards that tell it to shut down within a second. There are input called Vsego and VSago that tell the power supply to stay on.

Hope you already resolve it, if not, here what I went through 1. Try to get a service manual for your model ($10-18) from http://www.service-docs2.com or similar place. 2. Open the back and follow instructions how to remove and test the SDR-D and SDR-U board on the far left (take one off, see if you could see half the picture). Inpsect the chips on those two boards, you might be able to spot the burned out holes (that would be the defected board, seemed to be a known issue for particular models) 3. If it is the board, go to ebay and get the pulled out board replacement ($70-90) I fixed my 50 inch plasma this way

I can't help you because after 26 months of ownership mine is doing the same thing (started on 7-12-09). Judging by the number of people with the same complaint I believe Hitachi knows that they have bad boards but refuses to replace them for customers unless they are within warranty. It also explains why the merchant that sold it to me in 2007 stopped offering Hitachi in 2008.
I'm disgusted because I'm anticipating a $300-$500 repair bill simply because Hitachi's design did not provide an external way of resetting it. Impossible to get to the menu to do a reset within 12 seconds before it starts the powering on booting cycle again.
Adding salt to the injury, mine is wall mounted and repair people will only work on it if it is readily accessilble when they walk in the door or if it is brought to the shop. Know what a 55" plasma TV weighs? Too much.

SecureEasySetup (Orange/White) The Cisco logo is the Router's SecureEasySetup button. It
lights up and will stay orange when the Router is powered on. The color orange indicates that
the Router is not using the SecureEasySetup feature, while the color white indicates that the
Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup
mode, the Cisco logo will turn white and start flashing. After the Router has generated
the SSID and WPA Personal key, the Cisco logo will stop flashing and stay white.
To clear the SSID and WPA Personal key, press and hold down the Cisco logo for five seconds.
The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to
indicate a successful reset.NOTE: SecureEasySetup is a feature that makes
it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's
Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.
Power (Green) The Power LED lights up and will stay on while the Router is powered
on. When the Router goes through its selfdiagnostic mode during every boot-up, this
LED will flash. When the diagnostic is complete, the LED will be solidly lit.
DMZ (Green) The DMZ LED indicates when the DMZ function is being used. This LED will
remain lit as long as DMZ is enabled. WLAN (Green) The WLAN LED lights up when
the wireless feature is enabled. If the LED is flashing, the Router is actively sending or
receiving data over the network. 1, 2, 3, 4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port.
Internet (Green) The Internet LED lights up when there is a connection made through the
Internet port. A flashing LED indicates network activity over the Internet port.
Good luck
