Trying to figure out if I have a faulty zsus board

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 stage 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. Viewing it in "Mosaic" will make surf easy.
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Hi im trying to find the number of the remote for a lg 50px4d plasma tv

For a 50PXDR-UA (is simular to your TV) the remote part number is 6710V00141T and the retail price is $43.88 from LG.

You can use any 2005 and newer LG remote because the common controls are the same. The newer remotes may have functions your TV does not and that is OK.

Here are two remotes that will work for your TV.

2nd link
Good Luck. I hope my information has helped you.

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.

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
