SOURCE: I own a 3 year

If I understand this correctly, since you connected one of the HDMI inputs to an X-box, you do not see any red in any picture from any source, not even the SD Photo display input. White areas in the picture are cyan colored; other areas are various shades of blue-green. Red areas are black. This is the worst case; it is not clear from your description whether this is what you see or if the red areas are just not red enough.

Try going to the Picture menu and changing Picture Mode to "Normal", and Normal to "set". Turn Color mgmt. off. Refer to pages 26-27 of your owner's manual (download here). If this doesn't help, try selecting different Color temp settings. Make a note of which combinations of settings are giving you good results and which are giving you poor results.

If you cannot get close to factory default color, download the service manual and post back so we can take a look at the numbers in the video processor's EEPROM (data memory). We can continue diagnostics from that point if necessary. You may want to compare the EEPROM numbers for the settings that give bad results with the nominal values given in the service manual - if one of the numbers for red is way off, that could be the problem. Please post back before trying to change any numbers in the EEPROM - we don't want to make a bigger mess, and it would be a good idea to figure out what is going on first.

All input except cable wire in have stopped working and cable only gets digital reception. what can I do to fix?


Sounds like tuner fault. Contact any service technician. Just do a reset to this set and check; before contacting anybody. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

TH-50PX77U inputs


Many times a computer's post screens will not show up a TV set, and once the computer itself has loaded the drivers and settings, the set may need to be shut off and turned back on for the HDNI or PC signal to be detected.

It is also possible the settings you selected for display properties cannot be displayed on the TV.

As far as the component video signal, are the connections correct? Sometimes people mistake the composite red, white and yellow for the composite system that divides the red, blue and green video signals.

While also possible, but rare- there may be poorly soldered connections on the "A&D" board (logic board) .

What type of cord do I use to connect my PC to HDMI


Hello
There are two types of connections can be done with PC to TV, according to TVs inputs. If TV has a VGA input socket, a VGA to VGA cable is necessary. If the TV has only HDMI input socket, a VGA to HDMI cable is needed.

Panasonic Viera TH-50PX60U Plasma is stuck on one channel. Only the power function works on the remote and only the On/Off function works on the TV. Any ideas??


Forced to factory default: press and hold [VOLUME ( - )] on the TV and press [MENU] on the remote 2 seconds. Exit: Unplug Power to reset.
If it does not help, the main board need to replace. For further questions, please add your comment.
