Hi!

We have had a fifty inch plasma hitachi P50H40 TV for just over three years. We have a computer hooked up to the TV and watch Netflix and Hulu. (No cable!). Suddenly it appears that the HDMI inputs quit working. We swapped out the computer to be sure it wasn't the computer and it wasn't. We can get the other inputs to work (not well since we are running it off a computer) but not the HDMI inputs. Any suggestions on getting the HDMI inputs to work properly again?

Have you connected something else through HDMI to the TV just to be sure it's not something with the PC's HDMI?

If something else works then double check your settings on the computer (if it's a laptop check your function keys for toggling the second display).

I'm assuming this is a problem with all the HDMI connections. Just so we're clear, is this so?

We hooked up two different computers to the TV and same problem. When we hook up the computers to a monitor with HDMI input, they work just fine. (The computers that is). So definitely a problem with the HDMI input on the TV.

Or the TV handling a PC signal through HDMI. Have you tried hooking another device up through the HDMI? Something that is not a computer? And is this an issue on all the HDMI connections? Some TVs have an HDMI connection that is specifically designed for receiving PC signals. It's usually an HDMI connection paired with composite audio inputs (red and white RCA connections).

If you're absolutely confident that it's a problem with the HDMI input on the TV, then you likely have an internal issue with the TV which I would not recommend attempting repair yourself. You could look around to see what it costs to have the TV fixed, but most places charge around $150 for diagnostics alone.

Well, I don't have any other devices to hook up to the TV. I do know that we have had this PC hooked up to the TV through the HDMI input for over a year and it worked just fine. We have tried to use all three HDMI inputs and none of them work.

I suppose the only other thing I didn't try was a system restore on the PC to see if windows downloaded some type of update that screwed up the setting.

I have searched other forums and have been able to find other people with the same problem but no solution. I do have a call into a repair place to see about the cost.

Thanks for your replies!

Well we were able to fix the problem by unplugging the TV and plugging it back in. Such a simple solution!
