are you using a PC to feed a signal or maybe a cable with an adapter?
I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

blinking 10 times is an indicatron that the power module has failed. The sensor detects a fault on one of its internal boards( 3) and goes into shut down protection mode. You cannot play board swap jockey to fix this TV it will end up costing 3 times more if you attempt it. It requires a specialist knowledge,tools and ability to read a circuit diagram and ensure voltages are consistent with manufacturers recommendations across all boards.
If its got extended warranty claim now before itv expires.
if not get quotes for repair from a professional It;s not a DIY
THanks for using FIXYA Please rate my help++++ Thank you

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.

Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your tv power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
