Samsung SMGUN55D6000SFXZA DC VSS-PD BOARD

so the TV I'm working on today it's a Samsung and there's the model number there anyway this TV came in here completely dead and the gentleman told me that every once in a while it would turn on well I couldn't get it to turn on for me at all and so I gave him an estimate I told him I didn't think is even worth fixing because these things are so cheap now and he said this TV goes in his RV and so he insisted that he'd like to get it fixed so I said okay I'll go ahead and do it so first thing I did was I started taking voltage measurements on my power supply board here and what surprised me as I noticed even my standby voltage was less than a volt now for those that don't know the standby voltage is produced by the power supply and it's usually around 5 volts well anywhere from 2.5 to 5 volts sometimes it's 3.3 and it provides power to the main board and it's it's the main board getting
