Sounds like either an LCD panel problem, or a video controller. First thing, connect an external monitor and test if the same thing happens with it. You may need to press FN + F8 together to switch the display to the external monitor. If same thing happens, there is a problem with the video card. Try to boot in safe mode and if same issue, you either need to proceed in getting a new video card/motherboard if the problem is happening even during the Dell BIOS screen. If it happens pass the BIOS screen only, you may try a reinstall or repair of Windows. If external monitor is okay, you'll need an LCD Panel repair/replacement. Let us know how it goes and your rating/comment would be appreciated.

There is a humming in back of tv.the sound always good but picture doesnt come thru and i get a green screen someetimes blurry with distortion.color wheel or dmd chip or lamp starting to go out


as my experience, the most possible reason should be the color wheel or its photo sensor board.

firstly try to clean its photo sensor board, or have to replace a new wheel.

i just have this wheel, when you need to replace it, contact me freely

The white wires from the two light fixtures get connected to the white wire from your power supply.
Then the black from your power supply goes to the gold colored screw on the switch. Lastly, the two black wires going to your light fixtures get twisted together with a third jumper wire. The other end of the jumper goes on the silver screw on the new switch.

Trying to hook up a pilot light switch to a gfi recp not having much luck with getting it to work properly i got 2 conductors from the panel and 2 conductors going to the gfi recp and on the switch i have...


It is unclear what pilot-light-switch is supposed to turn on-and-off.

Option A) pilot-light-switch is going to turn GFCI on-and-off
Option B) pilot-light-switch is getting power from existing GFCI circuit, and switch controls another Load (light, fan or motor) located elsewhere.

Add a comment at any point.
Bare copper wire always connects to green screw.

1) I have a Cooper pilot-light-switch in my office.
Black Hot wire from breaker always connects to dark-colored screw(s).
White Neutral wire from breaker box connects to silver-colored screw
Wire going to Load (light, fan, motor) connects to brass colored screw.

2) Two things happen when pilot-light-switch turns ON:
a) Pilot light turns on. This circuit is powered by black Hot wire, and circuit is complete with white Neutral.
b) Brass screw that had no power, is now powered.

The GFCI:
Hot from breaker always connects to brass-colored Line screw
Neutral from breaker connects to silver-colored screw that is opposite Line screw.
If other switches and plugs are going to be protected by GFCI, they connect to brass Load screw and to silver screw that is opposite Load screw
geno_3245_83.jpg

Option A) You want pilot-light-switch to turn on GFCI receptacle.
a) Wire pilot-light-switch as described above
b) Black wire from GFCI line-screw connects to brass screw on pilot-light-switch.
c) White wire from GFCI silver-screw-opposite-line-screw connects to any white Neutral.

Option B) Pilot-light-switch is getting power from GFCI receptacle AND you want pilot light switch protected by GFCI.
a) Black wire on pilot-light dark screw connects to Load screw on GFCI
b) White wire on pilot-light silver connects to silver screw on GFCI that is opposite Load screw

Option C) same as option B except pilot-light-switch is NOT protected by GFCI.
a) Black wire on pilot-light dark screw connects to Line screw on GFCI or any Hot wire
b) White wire on pilot-light silver connects to silver screw on GFCI that is opposite Load screw or to any Neutral wire

I need a wiring diagram for hayward pool filter model K48m2n11b3


Are you trying to wire a pool pump?
I found manuals at the Haywood site > I saw nothing for K48m2n11b or anything close to that number
http://www.haywardnet.com/inground/products/manuals.cfm

But lets work on the problem and see if I can give you some help:

After opening a few manual and searching for the word 'volt' and 'pump' ... each manual talks about 'pumps' generically, as if the pump is a separate purchase item.

Lower down on the manual page they have a list of pool pumps. A search for the word 'volt' inside the pump manuals says 'match supply voltage to motor nameplate voltage.'

As you know, each electric device has a label showing voltage, wattage, etc. Your pump should show 120Volts or 240V. I didn't see any mention of 3 phase wiring, so I assume your Haywood pump runs on typical residential wiring? And that you are not using 440Volt or 3 phase.

The 120Volt pump will have a black, white and bare ground.
The 240Volt pump will probably have a black, white, red and bare ground
The 240Volt pump could have a black white and bare ground

First the 120V pump:
The 120Volt line from your breaker box will have a black Hot wire, white Neutral wire and bare ground >>> this wire connects color-to-color with pool pump

Next the 240V pump with black, white, red and bare ground
a) The 240Volt line from your breaker box can have the same 4 wires, in which case they connect color-to-color
b) The 240Volt line from your breaker box could have a black white and bare ground, in which case the black goes to black, the white goes to red, the bare coppers are connected, the white pump wire is capped off and not used. If pump does not operate with this wiring, another line from the breaker with wires that match pump might be necessary.

The 240V pump with black white and bare ground
a) The 240Volt line from breaker can have black, white, red and bare ground, in which case the black goes to black, the red goes to white, bare grounds are connected, the white wire is capped off
b) The 240Volt line from from breaker can have black white and bare ground, and this connects color-to-color to the pump

HOW do you know if line from breaker is 120V or 240V?
If you know which breaker wire is connected to, then it's easy
If you do not know which breaker
-turn off power
-separate wires so they can be tested
-use ordinary tester
-stand on dry boards
-tape tester leads to sticks so hands are away from power

-turn on power
-test each wire to bare copper
-tester lights up on Hot wire
-120V line will have 1 Hot wire
-240V line will have 2 Hot wires

Gateway laptop mx3414-black screen cannot load windows


Try going into safe mode upon startup by hitting the F8 button. If it does then hit safe mode to get into your computer. Go to start>accessories>system tools>system restore. Follow the wizard to restore your computer to a date earlier than when you started having problems. Let me know if you have any problems or questions.

Laptop cannot go into p.o.s.t. when it does.....


It could be the graphics, but it is a process of illimination as always. When you boot your pc keep pressing F8 and see if it will boot into safe mode. When in safe mode select 'Last known good configuration' as this may cure the problem. If that doesn't work boot into safe mode again, but this time select start windows in safe mode, if this works ok then it maybe a driver problem, probably either the wireless card or graphics, try uninstalling the graphics driver first in add/remove programmes. Restart the pc and windows should find it again and install the driver, if on the next restart the problem returns then it is the graphics driver so download a later version from the acer web site.
