Hi! I have a Panasonic TX-P50C3B I just bought a couple months ago. Everything is great except for when I try to plug in my computer into the HDMI port. It just stopped working. It's been fine so far, but now I'm not able to see my laptop screen through the TV set. I have tested the cable and the laptop and it works fine on the other set we have at home so, I'm pretty sure the source of the problem is the TV set. I would really appreciate your help! Thanks a

Please unplug TV from AC outlet and replug it after 5 minutes then check HDMI port.

your HDMI output is bad

Probably not, but your insurance should pay if you have a renter or homeowner policy.

You need to select setup from the TV menu then switch the Viera link on. I think retuning must have switched it off.
This worked for me

The way to solve the problem with the TH-50PZ80U blinking light problem is to not buy Panasonic Products. I have had my TV about 21 months and it has started with the blinking light problem, just out of warranty. Panasonic is aware of this problem and refuses to do recall or fix the tv unless you are within the warranty or have bought the extended warranty. Legally they are within their rights, but I am also within my rights to air my complaint and inform others of this below par product. Who wants a TV that they have to unplug for a while and pug it in again for it to work. I want to push the power button and it come's on. I will never purchase another PANASONIC PRODUCT.
