Where to buy back light inventer board for 50 in lg plasma tvmodel no 50px4d-eb

POSSIBLE that the main power supply has failed which is the SMPS unit . So please check on the link below and check the power supply unit in the TV.

Hi there
Try doing a system reset on the TV, by unplugging everything from it, then wait 3 minutes and plug the power lead in only. If it works, then plug everything back in one by one. If the problem persists it may be that the software has been corrupted in an update process, which can be performed at night via the aerial signal (this may be why it was turning on at night). In which case contact the TV manufacturer.
Hope this helps

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 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

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
