My ultra vision stopped working the red light comes on showing power but the blue light will not come on and I get no picture or sound. Any ideas? Thanks

SOURCE: Hitachi 55" Plasma HDTV, 1 yr old, suddenly lost picture and sound, but power light still on.

It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.

In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.

I hope this helps

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 boards if they are bad you need replacement boards or you can send them off to be repaired. 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.
