This is a very common problem with model. This problem is your Z sus Board. NOT your power supply, or Y sus board. There is a pair of Diode that goes bad. Your only solution is to change your Z sus Board. Part Number 6871QZH036B average cost $237.00

You could replace the boards yourself, however it will probably cost in the area of $500.00 to do it regardless if you or a service company repairs it.

I have A LG 50PX4D TV the display has gone off


Most likely the tv has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If its under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

Sounds like a factory issue. You should call lG directly and explain it to them. They're likely to get you another unit.

I have one here next to me when I pushed power the green LED started blinking until it brought up the picture 1 blink per second about 8 blinks. i am on the tuner input it may vary on different inputs also if it blinking like 1 blink pause 4 blinks or some pattern like that that is tech diagnostic error codes. if the tv is working you should be able to get a menu or on screen display even without an input attached. Also I only heard 1 relay click in the back
