    I have the same problem. I tried for the last ten days to contact hitachi. I finally got someone on the phone tonight. I will give his name. DONALD employee # 25956. He told me I was on my own. My monitor is only 15 months old. $1,800 for a set that gives you 15 months is ****. He said hitachi will not stand behind its product 3 months past its year. Yes, its the same P50H401. I think we should start a web to see just how many of this model is crapping out. It is the powerboard and many offmarket companies sell used or new boards to fix the problem. Just one thing. If powerboard didn't **** out in time, you could have more problems. Pot luck if ya buy an after market powerboard. So, for me. I'm buying an after market powerboard $20 board $10 shipping and I will take my chances. If I lose, I will send it out to my closest service man.

    I have the SAME problem. This TV is only 11 months old in my house!!! I am beyond angry. They said I needed a "software upgrade" and is mailing it to me. All of my information was taken by the rep on the phone. I paid 1600.00 for this huge piece of "landfill-er". I am thinking they have an obligation to either fix the problem, or replace this television. Any changes in your situations to the other posters?? Let me know. Paul

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

Hitachi p50h401 the power light keeps flashing

If you have a flashing red light, try this first: The flashing red light is, according to the Hitachi service manual, an indication of exactly one problem. It is that the fan (internal, blows air over the power supply heat sinks) has failed. In my case, it failed by continuing to spin (very confusing), but put out a signal (3V on the white wire of the fan harness) that it has failed (I had to look up the data sheet on the fan to figure this out). A new fan from Arrow $10 fixed the problem. If you suspect your fan, spinning or not, you can safely short the white to the black wire to see if your TV remains on after being turned on (solid red light), and then try turning your TV on (blue light) to see if it works.

I was watching my 50"

Hello williams6590,

Welcome, and thank you for using FixYa!

Your problem is the X-Sustain Board. There are a large number of componants and connections on this board. I recommend purchasing it from eBay! and then having a TV Repair Professional install it.

Here is a link to purchase the part:

Blue Light comes on but no picture

Hi, do you still have sound. Can you control your volume. It might be one of your sustainer boards. Please let me know. It could be your SDR boards too.

My hitachi P50H401 will not turn on. No sound no

check your sdr boards. you can test them with a multi meter. they are known for going bad. what happens is the two caps by the output go bad on the power supply and they make the sdr boards burn out. you can replace the two caps and save lots of money. then please check out this web page

This web page has info about repairing these. The 4 flashing lights maybe the x sus or the y sus but it's still a good idea to check the sdr boards since its a common failer. I had one tv with a bad sdr board flash 3 time and another set it was flashing 4 times.

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.
