if will tell you how to trouble shoot this tv. these tv's are known for two caps in the power supply to go bad and they need replaced then you have to test the sdr buffer boards if they are bad you need replacement boards or you can send them off to be repaired.( Repairing the buffer boards is a lot less then replacing them ) the link for the repair guy is on the page. this guy also sells the repair on ebay but if you contact him directly i beleave the price is lower. just tell him you were send over by home theater shack.

my hatachi hd/1080 tv has a solid blue light on and it wont turn on i push the reset button on the bottom right and it still wont turn on

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 http://www.hometheatershack.com/forums/hitachi/38229-hitachi-p50h401-led-flashes-3-times.html

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.

Ur power supply it dead.must replaced.

Here's a link for a replacement cord for a model P50H401:

I think you have problems with the digital main PWB.

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

I write the same in other consult
