No display on interface. There’s 120v coming in so there is power.
Replaced main board with DC92-01621D. Board blinking slowly red led. When pressed power on at the interface, the inverter starts blinking green but no display. Looks like there are different version of the main board from A to E. The model number is WF42H5200AW/A2 big space then 11. Am I using the wrong board version? When I look up the model number at Sears Parts Direct I only see two version which are 00 or 01.
On all parts look ups for Samsung or LG we call either Marcone or Union to verify. I would call you local PDA to have them look it up. If it is the correct board, then run it through the diagnostics with the technician manual link below.
Got the right version of board and got it fixed. Thanks again.
