TV will not turn on just green blinking light
If you paid a low price like $20 to $60 for the lamp it may not be an original replacement and may have failed.
But another thing it could be is to check the lamp cooling fan(s) where you might have to take some of the TV apart to do it.
If they have lots of caked on dust it would kill a lamp due
to inefficient cooling.

The Power Light is Red
yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.
Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

Reset air filter
Page 58 of the user manual says that after cleaning the filter when the power is turned on, you will be given the opportunity to reply "Yes" to the question "Did you clean the filter". I suggest you go through the motions of cleaning the filter again, removing the necessary parts. Then replace the parts, turn the power on, and watch carefully for the message "Did you clean the filter".

My Panasonic PT-40LC12 turns on for about 15
Best that you have to test the ballast board for faulty parts, the problem is, this need to checked with an experienced technician because lots of parts in that board involved like the driver transistor, resistors, capacitors and of course the ballast itself. Easiest way is to swap a new new bulb like what the shop do, they have an spare bulb to test the board if functioning because there is a sensor once didn't detect the bulb connected to the ballast board it will be disable by the processor. If you want to fix it yourself then you have to buy a new bulb or if you can find a spare one much better. Also, bad solder joints must be consider because it will do the same fault like what you've encountered right now.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

When I turn the power
Have you checked the thermal Fuse that is located right above Lamp? These sets had problems
with Thermal Fuse. Is all of the Fans working ? Lamp Fan?
Ballast board is what powers Lamp on. You need to also check 2 thermistors,they are known to be bad.
