Question about Panasonic Viera TH-50PZ80U Plasma TV

Open Question

No picture via HDMI cable

Panasonic TH-50PZ80U TV is 2 months old and picture output is through an HDMI cable from a satellite cable box. Everything was fine then all of a sudden the TV displays a "SHUTDOWN IN 3 MINUTES" message. Since then I can't get a picture through the HDMI cable but I can through component cables. I have 2 HD satellite cable boxes and neither will ouput a picture via HDMI to this TV. I've swapped HDMI cables to ensure the HDMI cable wasn't bad and still no picture.

    I have the same problem. I just took my tv off the wall to hook up a Wii & when I reconnected the HDMI inputs don't provide a picture, but all the component video work fine.



    Does anyone have a clue?

    Same issue for me with a TH-50PV80H. The problem started when I connected a PC via a HDMI cable to the TV. Now I just get a black screen - no picture or sound.

    Occassionally, the PlayStation - connected via a HDMI cable will work - but only for a hour or so and then I'm back to a black screen for all the components.

    Connecting the PC via the the VGA cable works (but the picture is not as good), same as the RCA jacks ... but then what's the point in having a HDTV.

    I received a post last night indicating that it was likely a faulty signal card.

    Good luck - I'm going to take mine in for service (and live without a TV for the next 3 weeks).

SOURCE: TH-42PX60U All output ports works but HDMI ports

Problem is with your ISP/Cable Company accepting the installation as one with HD clients, which while
not necessarily costing you more, must be specified to the cable box by your installer.

Make the call.

SOURCE: Thunder storm came thru...my th-50pz80u HDMI ports

I think you would be better having the set to repair shop. It might be not just those ports that has been affected. Modern devices are full of static sensitive parts and lighting is a bit more powerfull than mere static. It could also have comprimised safety features, to prevent fire; for instance. I would take it to a Pansonic service center to be fixed to be on the safe side.

Whats the best way to install a panasonic viera tc-p50x3 to a yamaha home theater receiver rx-v371 to a panasonic blueray dmpbd75 using dishnet work hddvr set top box


connect your blue ray and your dish net with hdmi cables to the amplifier than monitor out hdmi to tv .in your dvd configuration you must make sure that hdmi audio is activated .ps not to be mean but this is a very low quality dvd because it does not have fiber optique audio output but it can still work, for your dis net it all depends on what type of digital audio output
is available , ill be honest with you this is a good job .

Tv will not turn on. Flashes 10 times. If we unplug/plug it basck in several times we can eventualy get it to work. Seems to be getting worse every day.


You need to replace the power supply, PN: ETX2MM704MGH. This 10 flash failure is common. I hope this was helpful, best wishes.

Cc box


Open the menu, then go to setup, there should be a closed caption options in there, also remember that CC can only be passed via a transmitted cable signal. If you have a Cable box or Satellite box connected via HDMI, or its pushing a HD signal (720p, 480p) the CC box is from the Sat or Cable box, test the settings on the box.

Killed by lightning, have power, no picture...


The warranty does not cover lightning, check if your insurance covers it.
A lightning strike on such panel ( HDMI ) is very difficult to repair and if not impossible.The HDMI connector is hooked to the ground of the TV set so everything could be damaged.
My advice is not to repair.

Sony Viao HDMI to Panasonic Plasma TV HDMI Input handshake


Try all of your HDMI inputs, one may be rated at the correct voltage to be able to display the video. The offical part that Panasonic was giving for this was PDPHDMIKIT, its basically a HDMI extender that regulates the voltage. The part is still available online, try partstore.com or andrews-electronics.

Just bought a 50 panasonic viera, when we hook up ps3 on hdmi cable, we have sound but no picture.


Plasma TV normally do not have the resolution required for PS3 unless the plasma TV is fullHD( 1920x1080p) pixels.

HD Ready Plasma = 1024 x 768p
PS3 Outputs = (fullHD)1920x1080 or (HDReady) 1280 x 720p.

LCD TV accepts the resolution matches the resolution the PS3 is outputting.

Panasonic th-50pz80 10 flashing blinking red lights


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.
