Hi,I having a problem with my LG OLED65B8PUA 65"..No pictures no sound,and only a stand by light which blink 3 times wen i power on the tv nothing else works,this happens suddenly i reach lg costumer service and because the tv is a year and months old they denied the warranty for only one month i being search for tips in YouTube but everyone have different opinion but nothing closer to what is happening, i get onto the point I don't know what else to do. This is my last shoot mine friends recommend me Fixya to post this matter and see if any one can put me on the right spot.. thanks.. sr.Alex

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

Take a camcorder and capture it, that should be enough proof that it's failing often enough to be repair right. When the picture goes out, can you see it dimly if you take a flash light to the screen? It might be a bad inverter.

I called my local Best Buy for our LG 37" and let me just put it nicely that I am no longer a customer of Best Buy after 8 years of patroning... Ours is 5 months old and still under the manufacturers 1 year warranty. After 2 hours of talk time to those "people" at Best Buy, I called LG USA directly (1-800-243-0000) and they are sending out a tech to repair whatever is causing ours to turn off by itself and not power up. This will be covered under the 1 year warranty and all I have to supply is the receipt to the repair tech. Hopefully, things will go well since I have now move on from the inept abilities of Best Buy. LG warranty is a nice alternative to paying The Geek Squad for sure.

yes i have had many problems with my lg plasma. i had to replace three boards in the back of the tv. it is most probably the y sus board which has failed.
