I just recently attempted to use the HDMI input on my Panasonic TH42PX50U (which I've had for a few years now). I have tried multiple devices and multiple HDMI cables, but when I switch to the HDMI input, I get no signal at all. I'm assuming the input is bad.

Has anyone else had this problem or is it a known issue? If I need to get the input replaced, does anyone know approximately how much it will cost?

I originally bought the TV as a floor model, so it's possible the input had been "abused".

Thanks for your help.

Could be bad or it could be that the source setting is not set properly. When you say multiple devices...what are they exactly? BD player? cable? If it's cable box, sometimes it gets kinda of tricky to get the hdmi handshake working. You have to elaborate more.

I have tried to connect:

1. My Comcast HD cable box
2. My Roku Netflix player
3. My laptop via its HDMI output

After connecting the device to the TV, I'm simply going to the input selector on the TV and selecting HDMI. Other sources work fine over component connections.

I don't see any other settings that would cause it to not work properly. I also updated the TV's firmware just to be sure.

I originally bought the TV as a floor model, so it's possible the input had been "abused". I'd inspect the little pins in the HDMI port for damage first. I'm presuming that you have the HDMI input enabled in the INPUT LABELS menu, and not set to SKIP.

It's entirely possible that the HDMI section on the input board is defective, it is a known failure point on TVs but is not all that common. It's even possible that the TV was returned by the original owner in this condition and you ended up buying it. The cost to have the input board replaced could be upwards of $600 - not worth it IMO.

Now a few questions - (A) Did you buy this TV less than two years ago, or more than two years ago? Do you have the receipt? What's the date on it?

(B)If you bought it less than two years ago, did you buy it with a good credit card? Because some credit cards have a feature where they add one year to the manufacturer's warranty where they'll pay an authorized Panasonic repair center to fix it during the second year.

I checked the pins on the HDMI input and nothing is obviously bent or otherwise broken. Would one bad pin cause absolutely no signal, or would I get a partial picture or some audio?

The HDMI menu option is selectable. I can select it and the input label is displayed for a moment on the screen after selecting it - but it's a blank picture.

Unfortunately I bought the TV more than three years ago. I think that any repairs will be out of pocket - although I definitely would not pay more than $100 to get this fixed. I can live with it - I'm just running out of inputs.

You can buy a nice Component Video Switcher for less than that which will enable you to use more Component devices.

I think that's what I'll go with for now. With plasma and LCD prices dropping, it's probably less hassle to buy a new one when I absolutely need HDMI.

It may be that the HDMI version of your source components that you tried are not comatible (i.e., too old) with that of the set. I had that experience once with a DVD player, since my set (Pioneer Elite KURO) had HDMI 1.3a inputs. The problem was solved by updating the firmware of that player (Sony ES).
