According to the manual, you should attempt to power on a few times. If the indications remain the same, call a service center. If this is a new lamp, I'd suggest putting the old one back in to see it the set fires up. If it does, you have a bad lamp.
Keep us posted.

Should I replace my lamp for my Panasonic 1080i htd t.v. pt-50LC14

Replacing a lamp won't work. There is not even one lamp in your TV. I'm afraid the lightening has done more damage than can be repaired. Even when some tech manages to repair te error, the TV can have the next error in days or weeks.
Try reading something about ESD. Electro Static Discharge and what it does to electronics. Electrostatic discharge

I recently replaced the TY-LA1000 lamp but I'm getting a yellow flashing light that goes on every 5 secs.I made sure that it was installed correctly and tried resetting the timer by pressing + and - o

Yellow flashing light? Did you get any picture? Bet, not!
It means: your lamp door interlock is not engaged: did you forget to turn the locking knob? Did you install lamp compartment door? That might be the only issue. Lamp timer blinks 'red", while TV works normally. Reset the timer, it's gone, along with annoying message. Yellow means: interlock or thermal protection is off. Try to repeat lamp installation procedure. then, you'll find out your mistake. don't need to remove the lamp. It would be "red", if lamp won't fire up.
good luck,

Green light flashes several times. Then TV turn off.

look for 1 of 2 lights in front of the tv. after the tv shuts down completley mine would turn back on for another 30-45 min after a good cleaning it will stay off and give a "power light" not Lamp light 2 flashes. I'm waiting on some help myself. But if it's the lamp light you'll need to replace the lamp....approximitly $600 from what i've read so far.

Well my mom was watching tv and it just shut off so then my mom turned it back on thinking she might have hit the power button accidentally. But when she turns it on it started blinking the green light for...

The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

Panasonic projection TV does not turn on.

Power LED flashes orange 1 x 5 secs. = 1 of 3 fans stopped. TEMP LED flashes 1 x 5 secs, = Temperature error. Lamp LED flashes 1 x 5 secs. = lamp ballast error. (check lamp 1st.)
Hope this helps.

Tv will not power up

yellow flashing power light codes: flashes 1 every 5 secs = one of 3 fans not spinning. 2 every 5 secs.= lamp cover open.

5,6,7,8,9,or10 x per 5 secs. are power supply voltage errors.
