Hi guys/gals, I need some help!
\- Samsung WF42H5000AW/A2 front-loading washer purchased \~3 years ago
\- My Samsung washer died last week and I was able to diagnose a bad PCB (power from wall to filter to main board, but no blinking LEDs on main PCB or Inverter board). I replaced the PCB with a new one, and now I have a red blinking LED on the Main PCB, a green blinking LED on the inverter board BUT when I press the power button I hear a "click" (relay) and then ... nothing. The display does not light up, and I am unable to get the washer to do anything. Once I unplug it, the relay clicks again. I am not able to make the relay click again using the on/off switch. All connections are tight.
The [Main PCB board](http://appliancepartspros.com/samsung-assy-pcb-main-dc92-01621e-ap5916794.html) they shipped me looks slightly different, but the website said it's compatible. Do I need to "flash" or "reset" it after installation? I just plugged it up without doing anything else.
Any ideas here, or did my display/controls die too? Sub-PCB - is this display PCB compatible with the main board?? Should be ....
Appreciate any help you can give. I don't want to drop more $$ on the [display board](https://www.appliancepartspros.com/samsung-assy-pcb-sub-dc92-01622j-ap5916803.html) if I don't have to!
