Everything in system works except video on DVD player, get message no sync signal


Usually when to devices like this won't sync is when they are not compatible on the resolution side.(ex. dvd can display 720 p and the tv cannot do anything below 1080 p. I would say that unless you have a new commercial plasma it is the opposite problem. The DVD won't go backwards to match the TV. Check that the DVD Works on another set and vice versa and repost what you find out.

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.

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 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.

Hitachi Plasma TV 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.
