Sony VPL-EX3 "Lamp cover problem", it wont switch

There is a small switch that detects when the lamp cover is securely tightened down, so that it protects the user from the high voltages, hot surfaces, excessive bright light in the eyes, and damage to the face if the lamp implodes due to old age and overuse.
so check if the switch operates when a toothpick is pushed up and down in the cavity.This model suffers this problem when the cover is slightly warped with old age.
so put a strip of folded paper between the cover plastic protusion that actuates the switch and the switch and secure the cover and see if this is all that is needed to activate the switch properly.

if it now works, you can try putting a small drop of silastic on the cover protusion and wait till it sets over several hours in order to lengthen it slightly so that it reaches the switch properly

Motor does not spin or turn over

this could be the result of a faulty switch, a loose connector, a faulty X-termination board, a pinched wire in the cut motor, a loose power wire, a head cover that is not engaging the AC motor switch, or a bad controller.
carveright recommended trouble shooting steps for this problem (i know different company but if similar product and the same problem, it should work):

  1. Check that the right clear cover hinge cover is not loose and that the switch is not loose. If either is loose it can affect the actuation of the switch button by the finger on the clear cover.
  2. Verify that the connectors to the switch are in place and tight.
  3. Verify that the cut motor switch (the one on the right side of the cover) is working by listening for the click as the cover is lowered.
  4. Take a small implement and manually depress the switch button by hand. If you can hear the click when you do it by hand but not when the cover is lowered then there is something wrong with the cover that is preventing it from depressing the switch far enough. Resolve this cover issue.
  5. UNPLUG THE MACHINE and remove the bottom cover. Check the seating of all of the connectors to the power supply, controller, X-termination board, and ON/OFF switch.
  6. Check the AC motor brushes for excessive wear.
  7. Check traces on the X-termination board for signs of a burnt trace.
  8. If none of the above steps solves the issue consult a senior engineer.

Cover open sign shows all the time

There is an interlock switch or sensor on all the covers. You need to open the cover and look for an opening in the cover it closes against. In those openings there are normally switches that a tab turns on to let the machine know the cover is closed.
The switch may have become dislodged, or more likely, the tab on the cover that hits the switch to actuate it has broken off and is not hitting the switch giving you that message.

HP Deskjet 5150 - top cover open

I had the same problem, and the cause turned out to be the cover switch not being fully pushed in. On the underside right edge of the top cover, there's a little triangular protrusion that pushes down a black rectangular button (the cover switch) when the cover is closed. The problem occurs because the flimsy top cover is made of plastic and flexes slightly when you close it. This means that sometimes, the right edge of the cover won't seat properly even though it appears as if the cover is closed all the way. When this happens, the triangular protrusion isn't fully pressing the switch down.

To test if this is this is happening, send a print job to the printer and wait for the "top cover is open" error message to appear. Next, open the top cover door and locate the cover switch. It's a little black button in a rectangular hole at the right edge of the doorway near the ink cartridges. Take a pen or a car key and use it to push the cover switch down. You can also use your fingertip to do this if it's skinny enough. If you keep the cover switch pressed down, the power button should start blinking to indicate a print job is coming through. If the print job actually starts printing, then you know the problem was the cover switch.

In my case, all I had to do the fix the problem was close the cover and make sure it was fully seated by firmly pressing down the right edge of the cover until I heard a plasticky "click" noise. After that, the problem went away.

Hope this helps.

B door open

There are two switches, so if you changed the one that was working....

Possible parts affected could be
- cover top
- cover fuser
- cover front assembly
- the switch
1) check the condition of the cover - top, front assembly and cover fuser closed?
2) on the cover top there is an "actuator", a plastic bit, which presses down on the switch assembly top - is that plastic bit broken, bent or deformed?
3) on the cover front assembly there is also an "actuator", check this
4) and of course same for the fuser cover
5) top cover, check the switch, disconnect the switch (P116-1) and press/release it - does that make a difference. If not replace switch
6) same procedure with the switch (P115-1) for front cover.

IPaq switches off

You need to examine your battery cover as one of the c hooks in your cover may be bent or broken. Basically, the hooks on the cover actually press a micro-switch that detects if the battery cover is on.

If your battery cover looks fine, then you may have a software problem. Try getting a firmware upgrade or simply doing a hard reset to see if the problem is still present
