LG OLED 55B7V respond to power-on button, PSU goes on for a second then stops.
No sign of picture nor sound.
Any advice?
The PSU has two main outputs. One +12V and one +24V. The 12V supply is running for like 5 seconds, and the +24V output shuts off after a second.
If disconnecting the loads, the voltages stays on both of them, until the diagnostics turns off the PSU.
Sourcing the +24V continously from external PSU does not change behaviour.
Thanks in advance!
