LG tv repair

[pwjones7625]

I have an LG 55 in. LCD smart tv. when the power is turned on the screen will flash for a second the go blank (black screen). both the power and smart circuit boards have been replaced and still has the same symptom. Any ideas?

User error?

I would ask for a replacement TV if it was their fault. Even if you find a new board, it's likely going to be expensive, and a lot of the times you're better of buying a new TV.
