SOURCE: screen flashes black

Hi this is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen blacked out, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

I have an LG 55 inch TV, model no.# 55LB5550-UY. When I plug TV into the outlet the screen flashes on and off rapidly. I have changed the power supply and the main board. Neither resolved the issue.

Sounds like an issue with the motherboard or a short in the screen circuits.
As it usually costs more to replace this than most sets are worth I suggest purchase a new one.

I have a 55" LG LED tv that has quit working.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. .
