Question about InFocus POWER SUPPLY CORD Multimedia Projector

2 Answers

Infocus projector power supply dead

I have several Infocus projectors (X1,X2, X3 models) that have blown the power supply. A couple projectors blew the power supply when my home had some furnace smoke issues.

I found two bad 2SK3568 FETs bad on one X3 power supply that had also blown the soldered in fuse. I bought a replacement X3 projector that apparently blew a different portion of the power supply (only the fan runs; no lights or any other function). Does anyone have power supply schematics or have any repair history/advise for what usually goes wrong with these units?

The caps dry out. look for bulging caps. you won't find a schematic for the ps boards. infocus had someone else make them. the problem seems more like a overheating issue. as for the other one with the "just the fans", check the colorwheel.

Load clattering on hp 4500 startup


if the boot process takes longer that normal, regularly goes back to reboot or you have other problems it could be a failing hard drive (Save all the files and folders to external hard drive and install a solid state hard drive --no spinning disc to fail)
if it is not that check the cooling fan operation for the power supply or chip-- about the only other things that have movement

My Dell 3115cn printer will not connect to the network (it still works on USB cable), hard to believe it's broken, so can the printer system be reset?


Try turning off the printer and disconnecting power plug from wall. Hold power on button for about a minute. Then replug unit and turn power on - it should then attempt to hook up to your existing network.

If no go, try reinstalling the software that initially came with printer and was used to set up the network

HOW DO I un-lock the scanner on a Brother MFC 7420?


Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: https://www.brother-usa.com/support/ModelInfo.aspx?R3ModelID=MFC7420 . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: http://download.brother.com/welcome/doc000387/ALLFB_UsaEngUsr_B.pdf .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.
