JVC LED 32 Inch TV, backlights off after ~3 seconds

Hello all

I am restoring a discarded LED TV and all my backlights come on briefly for about 3 seconds an then off. My usual  power supply voltages seem Okay although I have noticed the 24 volts Is only there at the logic board for those 3 seconds. I felt there was an issue with the power supply and changed it for a new one but with still the same result. Is there some fix I can use to maintain the 24 volts which I guess I will need to keep the baclights on? Thank you. For Any advice would be grateful. My email is
