I had the same issue. I am going to replace my scan buffer boards. The upper half of mine works but the lower half is black so I would replace the lower Scan buffer board but in case of future issues I have ordered both upper and lower for $44.
The scan buffer boards are fairly simple to locate. Open up back of tv there are two biffer boards identical. The item or product code on them contain letters either SU or SD (Scan up and Scan down)Look up tv parts and item code you will find a place to order or just get the 1 800 number from tv manufacturer.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

would love to know if your problem was fixed - ours went out only 3 years old.

Try the SAP - same thing happened to me and had to cycle through the audio tracks to get audio back on for that one channel. Good Luck!!!

THERE ARE TOO MANY THINGS THAT CAN CAUSE YOUR PROBLEM. POWER SUPPLY, SIGNAL BOARD, SUSTAIN BOARDS AND DRIVER BOARDS.
TAKE IT TO AN AUTHORIZED SERVICER.

On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

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