As crcelect suggests you can run the TV on RCA. You should also be able to use coax directly from your cable box. If you don't have cable you can use an rf converter to connect coax.
I have exactly the same problem with my Panasonic TH-42PX75U. I've been told that I may need to run a setup on my cable box to fix the problem. If I find a solution I'll provide details in a future post.

the wii leads are colour coded look for the colours on tv then switch tv into that input mode e.g ( common or EXT ) make sure wii is on

Either the buffer board is bad or the plasma panel,sometimes it coult be bad connections on the interconnect ribbon cables from the plasma panel to the buffer boards.

Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.

But need to measure the connection SC2, if it short, it will be the SC board.

The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.

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.

Direct Code Entry

1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

Code Search If after trying "Direct Code Entry" your device does not respond, or if your brand is not listed, try doing a search of the code library for your code by following these steps.

1. Manually turn on the device (TV, VCR, etc.) to be controlled.
2. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
3. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks once, then stays on.
4. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks, then stays lit.
5. Press and release MUTE to install the code. The indicator light goes off.

Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry. Then follow the steps above for Code Search.
