One day my TV didn't want to turn on but the power light was blinking. I called a tech who came to my house and told me that the problem was the lower board. I bought the board and decide to replace it myself, now the TV turn on but it has line on the lower part of the image.
Double check your connections

It must be a red light flashing as the 50V500 has no green lights on it. Make sure that when you place the lamp cover back on that it is activting the micro switch behind it. Otherwise the set will assume the door is open and won't ignite the lamp. Otherwise the ballast could be the issue.

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.

Hope you already resolve it, if not, here what I went through 1. Try to get a service manual for your model ($10-18) from http://www.service-docs2.com or similar place. 2. Open the back and follow instructions how to remove and test the SDR-D and SDR-U board on the far left (take one off, see if you could see half the picture). Inpsect the chips on those two boards, you might be able to spot the burned out holes (that would be the defected board, seemed to be a known issue for particular models) 3. If it is the board, go to ebay and get the pulled out board replacement ($70-90) I fixed my 50 inch plasma this way
