Hi,
I have an LG 49UF770V here. On arrival it did not power up at all. I replaced the PSU and that made no difference. I replaced the main board and the TV now starts, the LED on the front flashes three times and the display comes on but there is no picture.
I have replaced the T-Con board today and that has not resolved it.
I am pretty sure the PSU is fine. The T-Con board also appears to be fine. I think the original main board was defective given it did not power up at all with that but I am beginning to wonder if the replacement main board is working properly. The problem is I can't source a replacement, the board is EBT64141201.
I have not been able to establish either what the three flashes on the LED on the front of the display means.
I am really struggling with this and would be grateful for any advice that can be offered.
Thank you
Matthew
