Hitachi power light blinking

Hi, from looking at the message board you look like the man with the answers.
i have a hitachi hd 1080 p50h401 television and the blue power light blinks three times then pauses and then blinks three times then pauses, etc. i've tried unplugging it and pushing the reset button but the tv won't come on and that power light keeps blinking.
do you have any tips that might help?
thanks,
ellen

    Light blinks four times pauses then does it again endlessly. Blue, not red.

    I have a similar problem to the people above (the blinking power light on Hitachi model P50H401, and I see that you advised them to change their SDR Printed Circuit Boards, did you ever hear from them as far as that solution working for them?

Does anyone know how to fix this very common Hitachi problem without paying a repair man? And if you did pay a repair man did they fix the problem, and how much was it? I absolutely LOVED this TV before this happened. :(

Same problem. Same attempts. I turned off main power under screen. Turned back on. Same blinking light. Then unplugged and turned on again. Same light. I switched off the main switch again and gave up after I read the above "you have problems with the SDR printed circuit boards." I have spent too much money on this TV as it is, so I went out and bought a new one. When I came home, knowing I had to wait three long days for delivery, I tried the TV one last time and ---whatdoyaknow--- on it came! A day later it is still fine. Tomorrow I am cancelling delivery if luck still holds. All I can figure is that unplugging it from the wall and powering off at the main switch did the job of completely rebooting.

    UPDATE--this is a sign to fix your TV or toss it to the curb. After I rebooted and let it "rest" for a day or two, it came back on. Lasted about four hours, then went blank again. Tried this twice more over the week, same results.

    Fujitsu is right--time to get it fixed, or get a new one, like I just did.
