check that the antenna wire is properly connected as the screen indicates that it is not working or connected properly

The best thing is to try to obtain the remote for it as some universal remotes will not do all functions. Look for it on the web or go to a seller of your product.

You will need to get a new remote.

I had the same problem. It appears to be due to a bad tv tuner. Turn on your computer and leave the coax unplugged. Leave it for a while (15-30 min). When you see "snow" on your screen, you will be able to use the source button to change to another input and see if you can get a signal. I am running my cable through a dvd recorder and using the AV input to watch tv. Also, my HDMI, component and RGB work fine. After thank don't try to access the TV source until you have had your tuner replaced.

need replaced A-BOARD
Manufacturer Panasonic Part Number TNPH0716ABS Description A- BOARD


After the installation of a new A board, unit has the characters "CHK" on screen. The usual reset procedures of [VOL -] and [MENU] or [OK] or [SLEEP] will not get rid of "CHK".

1. Enter the service mode by holding down the [VOL -] button on the TV (main unit) and simultaneously pressing the [INFO] button on the remote control three times.
2. Press the number [2] key on the remote to highlight [SRV-TOOL].
3. Press the [OK] button on the remote control to select [SRV-TOOL].
4. Use the [DOWN ARROW] on the remote control to scroll down to [PCTC].
5. Use the [RIGHT ARROW] button on the remote to open the box to the right, then press and hold down the [MUTE] button on remote to display Time/Count.
6. Press and hold the [RETURN] button on the remote control until the TV turns off.
7. Immediately press and hold down the [VOL -] button on the TV (main unit) and the [MENU] button on the remote. The TV should come up in the Self Check mode.
8. Remove AC power.

You will see that there is a power button on the bottom right corner of the back of the unit (item 25). Turn the unit on using that first.

I have a Dynex t.v, but my remot control doesn't work .
