You may have to activate that imput through your menu.Alot of plasmas have the ability to mute imputs.

A fuse has probably blown inside the TV, I had something similar with a panasonic TV a number of years ago. Open the back up and use a continuity tester across your fuses till you find the right one...................dont forget to unplug it first !!

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

Anyone have issues with the HDMI input on this TV no longer functioning?

SOURCE: My TV has little green dots all over the picture.

that is called diffusion. that can be adjusted out in most cases by adjusting the y sustain pcb but can also be the main pcb, the logic pcb and panel itself but not likely
