If the set is totaly dead then the first place to start is with the SMPS (Switched Mode Power Supply). However sometimes other parts will cause the Power Supply to short out as well. If and when the Power Supply is replaced and the set comes back to life and operated with a Menu then you are probably ok. Note: On your set when replacing the SMPS the tech Must adjust the SMPS voltages to the Panel Voltages. There is a sticker on the Panel that list the voltages the tech must adjust on the SMPS.

MFC-9840cdw with "print unable 36. Sometimes I can reboot and get it to print a few pages, but then the error comes back. I've cleaned and checked for ink, paper,etc. everywhere, but can't resolve th


Ok, here is what I found with a bit of internet research. Print Unable 36 error stems from an issue with the High Voltage Power Supply Printed Circuit Board (HVPS PCB).

Possible issues are:

1. The tech accidently didn't properly seat the connectors when re-hooking up the cables if indeed he or she removed any in dealing with your Error Code 32. "Check the two harness connections between the transfer HVPS PCB and Registration Relay PCB, and the two ones between the Registration Relay PCB and Engine PCB. Then reconnect them." If you try this yourself, make sure the machine is unplugged and cycle the power switch to discharge any power supply capacitors. You don't want to mess around with the high voltage. Best is to take the unit back into the tech for him or her to check it out.

2. The HVPS PCB has gone bad. If the machine is still under warranty (check for your receipt), don't go any further and just call Brother customer service at 1-877-436-2665. According another user, the part was shipped overnight and a tech came out the afternoon after he called and installed the part within 2 hours.

3. The Engine PCB failure. Replace the Engine PCB assembly. See warranty service recommendation above.

Start with #1 and if that doesn't resolve the issue, move to the next steps. If under warranty, have Brother do the service. If out of warranty, you'll have to examine the costs vs. buying a new machine.

We just bought another Brother printer (an MFC-9460CDN on closeout sale via Best Buy (~$329.99 and free shipping to the house)). Love Brother machines and service. Very robust in general and fairly easy to repair. I just replaced an MFC-8840DN that is more than 10 years old, and still working, though getting worn out.

Hope this helps.

I have an emerson tv and it will not power on at all. The little light wont even come on.


Solution 1 was just step 1. If the outlet gets power and the fuse or circuit breaker is ok, then U have a bad tv. That seems to be the most common problems with lcd's when they go bad. They either give the blinking light and not coming on, or they go completely dead. Most common causes are a bad power supply or a bad board/PCB/Circuit board.
