Error code 48:
"PON-SHORT 3.3V or 5V switched supply short PWB-MAIN Failure"

Indicating a power-on short of one of those voltage lines.

I found the service manual here: https://is.gd/wxc9tL

I guess it depends on what you feel comfortable doing. I was only able to find a replacement here, on ebay


That seems pretty high for a power supply, but it's the only one I found available from a quick glance.

PWB-MAIN does NOT equal Power Supply. Two different items.

Bearing in mind that you have WD-92840 and manual is for WD-92842. I don't care how similar they are, go with the part number on the actual part.

Page #39 Boards drawing.
Page #40 Boards Parts Numbers.
Page #9 Boards removal.
