    Purchased this tv in Nov 2007. It worked fine until today Feb 9 2008. It just turned off. when i try to turn it on using the power button on the tv. the stand by light clicks on then the blue on light blinks a few times and turns off within 3 seconds. I've tried everything, unplugging it. holding the power button for 30 seconds. nothing works

    I am having the same problem with 2 of these televisions. I am going to send it to a certified repair shop because I think it may be a manufacturing issue. It sounds like it is, but I cannot tell until i have a certified shop check to see if Hitachi has some recall on this part or an automatic repair and replace option.

WHY WON'T MY HITACHI PLASMA TV SHOW PICTURE OR SOUND? WHAT DOES THE BLUE LIGHT ON THE FRONT FLASHING 4 BLINKS MEAN?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

No picture or sound, just blinking power light


Hi...I am sorry to say that I had this exact problem. It ended up being the upper and lower panel drives. I contacted Hitachi and even though my unit was out of warranty, they agree to pay for parts. I paid for labor myself, and it cost me $199.95.

Good luck with it...let me know how it turns out for you.

Picture blinks in and out every few seconds


The lines in the picture and the blinking makes me think maybe the digital / logic board is going bad.. you will need a tech to resolve this and it will be expensive.. In time you will loss the picture altogether as the board will get worse.
