TV was on went back into living room and TV was off. Power button light blinks 10 times then few seconds stops then repeats. TV never did that before. Unplugged it waited and plugged it back and still will not turn on just blinks.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

if your TV blinks 10 times. Possible solution should be to check and replace on the G1 board Q1600 and Q1601 if shorted and R1614 and diode D1605 open.

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also
ensure that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem with no receiver box
or dvd connected.
If that does not work, and you keep having a flashing
led on front of the TV, and tv turning off by itself after a while,
that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
protection circuit.
2 The protection circuit detected a wrong
voltage or abroken contact, identified an internal fault and kicked in
, startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults
that can occur are a blown capacitor on power board, a
convergence IC has blown, or a fault on Digital board.
Check also
the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you
can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

This usually is a result of a failing power supply or any of the SOS circuit boards. Power supply's and boards are expensive to replace and in most cases not worth the cost to have repaired if you are out of warranty. However this is a known issue for Panasonic and I have seem them repair your model sets at no cost. So it is worth giving Panasonic a call and see if they will fix this for you. If they agree to fix it they will send a tech to your home for repairs.
