Hi all,
I have an LG 65UH5500 built in 2016 that won't turn on and stay on. When you turn it on, the screen comes on like normal and shows the LG logo, but turns off in less than a second (or very quickly). I took off the back panel, read through a couple threads here, ran through Bud's TV troubleshooting PDF, and have come to a stopping point.
On the power supply board, there is a connector with 80V and 13.2V connections. With power plugged in and the TV off, these measure 63.6V and 9.7V, respectively. The TV won't stay on, so getting voltages with the TV on is a bit tricky.
I looked at all the capacitors and did not find any evidence of failure. Fuses appear to be intact as well.
Are there any troubleshooting tips I can use to help diagnose the issue with this TV?
Thanks!
