Sounds like main board is faulty. These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

SOURCE: power button is green - no blinks / no picture / no sound

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

No power?
Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you could save $300 at least!

Lg 50pc3d screen and z50pj240 could fit viseversa?


No, they have completely different displays - one is made by LG and the other by Samsung.

You can't mix those two.

Sorry, don't kill the messenger :-)

My LG 50PC3D was manuf in June 2006. Just today the screen is black and flickering 1 wide band of dimlit grey slightly off to the left. The indicator light stays solid green. Any idea what may be causing...


I would first check for swollen capacitors on the power supply board. This model has about 9 under rated capacitors that usually go bad. The original caps are 3300 uF rated at 10 Vdc., and they should be replaced with 3300 uF capacitors rated at 16 Volts DC, 105 degree types. A failure on this board could also affect the other boards in the set so correcting this problem may not remove the symptoms.

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).
