HP LASERJET 4 PLUS, 4M, 4M PLUS C2038-60004 FORMATTER BOARD RH6-3201 W/ HOUSING
I bought this because the service manual for my HP4M+ printer said it might fix the problem, being that the LED display is blank at all times. It said to try these measures:
Check control panel cable
Replace formatter board
Replace control panel
I don't know how to check the cable, I figured it's probably alright. Yes, I could be wrong. One end of that cable fits into a connector on the control panel. That comes off easily enough, it has to be unplugged to remove the top cover of the machine, which is necessary when replacing the formatter board. The other end disappears into the printer and I didn't see anything in the service manual that shows me how to get at the other end. So, I just figured I'd skip the cable and just replace the formatter board and if that didn't fix things, get the control panel. I received the replacement formatter board yesterday and swapped it out with the original and the problem persists. The listing for the formatter board says they accept returns for 14 days, I pay return shipping. Should I return it? Is that ethical? I suppose yes, would you? I'm guessing that return shipping would cost me ~1/2 what I paid for it.
I bought a used control panel last night for $30 shipped!
