SOURCE: Power light blinking 2 times

2 blinks means the unit is having problem with 12 volt supply.
while power on you can check 12DC on power supply before shutdown.if the voltage is constant before shut down I would recommend to replace D board.

SOURCE: Plasma tv picture not coming on and power light flashing

Yes, you have power supply issue.
the power on circuit is malfunctioning and the flashes is the indication that the voltage levels for the power on regulation is not correct therefore shut down to protect the circuit from further damage. You TV unit needs servicing by an plasma TV specialist.
Also check to see if you do not have the TV in sleep or hibernation mode.

Lg plasma menu screen wont go away


The exit button on the remote may not be working or some other button on the remote is jammed. Try removing the battery of the remote and switch off the TV manually and the input power. Wait for a few minutes and then switch on the TV manually. The try changing the menu from the TV control panel. If nothing works, this is a case to be handled by a qualified service technician.

Brand new LG plasma stuck on test screens


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope it may help you;

Lg plasma mt 42pz10


I wish I had an answer for you but I'm in the same boat. I've got a 42pc5d and it's doing the same thing. I'll turn it on using either the remote or the power button on the unit itself. The LED will blink either two or three times, then shut itself off. I tried plugging the unit into a different outlet. I tried unhooking all inputs (PS3, DVD player, antenna, etc). The tv was still shutting itself off. I called tech support and the lady who answered asked me if there was a power button on the unit. Well, of course I understand LG has hundreds of models but I felt like I was dealing with someone who didn't care enough to even open the manual to see for herself. Anyway, after a "reset", the TV is now nothing more than a very expensive paperweight. To say I'm displeased is an understatement.
