If no red light problem is most likely on the power board---set used up to 3 mechanical black power relays and sometimes they stick open or shut---follow cord inside and tap on them to see if one is causing the problem.
Hitachi TV also Model # 46UX7K, Serial # W1H002013. I was hoping I can get help
with this one too. The picture is dark and has lost most of it's color. I don't
know if the color is off because it is so dark. Is there
parts that I can buy from you to fix this problem.
power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.
You didn't do anything to cause this. The thing is that there are several possible causes for this problem. They include convergence circuit failures, power supply/regulator issues and deflection/high voltage malfunctions. The only way to determine the cause is to have an hitachi authorized servicer out to diagnose this. Be aware that the repair costs could be $300-$600 depending on which circuit is causing the failure.
