Have have a westing house switch no.77286 with a l123 and colored black yellow blue and white color wire which color goes to those no.


The black usually goes to the L. The others you'll have to play with, If it's the correct switch. You should mark down what color wire goes into which slot BEFORE you take them out. DO NOT CUT WIRES!

How to set up??


First, you have to make sure that the thermostat is set to conventional and not heat pump. Then, the best way to know where the wires go, is to mark what terminals the came off of from the old stat. If that isn't possible, the next best thing to do is go to the unit and see where each wire goes. This is because the wire colors are not exactly set to any certain standard. It's at the discretion of the person installing the system in the first place to use whatever colors they like, to work any part of the system the choose.
The basics/commonly used colors are:
Red- R terminal- Power
Green- G terminal- Fan
White- W terminal- Heat
Yellow- Y terminal- Cooling
Blue- C terminal- Common
Heat Pump Thermostats use more wires, such as:
Orange or Black - O/B terminal- Reversing Valve
Brown- W2/Aux terminal- Heat

My suggestion would be that your black wire is for your cooling(Y), and all other colors wire up to the corresponding terminals. There are many systems that are ran only by 2 and 4 wire setups, therefore, it's possible that whoever ran your wire initially did not have a yellow wire in the strand. Also, if there is a yellow wire in the strand(possible 7wire strand), it could also be that the wire had a short and they switch the wires to bypass the short. Hope this helps and Happy Holidays!

I have no color on my Samsung Flatscreen TV


Hello,

This means absolutely no color - equivalent to a black and white picture. Not even a hint of color.

First, confirm that the source is actually in color - try another channel or input device.

Next, check the settings of the color control - it may have accidentally been turned down. If your TV has some kind of automatic picture mode, try turning if off and adjusting the color control. Try adjusting fine tuning if you have such a control and the problem is with a broadcast or cable transmission.

At this point with a confirmed color signal source, there is a problem with the chroma circuitry.

Note that to the average person, the obvious question becomes: is my color picture tube bad? The answer is a definitive NO. It is virtually impossible for a defective CRT to cause a total loss of color. A defective CRT can cause a lack of a primary color - R, G, or, B or a short between two colors which will mess up the color but is not likely to result in a black and white picture.

Some possibilities in no particular order:

Weak signal or defect in tuner/IF causing loss of signal strength.

Coler killer set too high (internal control) if it has one.

Defective part around the chroma chip/circuit. Faulty color oscillator.

Bad connections in area of chroma chip/circuit.

Defective chroma chip (don't suspect this first just because it is probably very expensive).

Try prodding the main board around the chroma chip with an insulated tool to see if you can make the color come and go.

I had one set where a $.02 resistor decided to open up causing just this problem - perfect BW picture, no color. Another had a coil with a broken wire.

How do I set my 5550n printer to print only black and white copies and color on demand?


If you go into control panel then go printer options you should see your printer icon. Right click on it and go printer preferences or printer properties and I think there is a colour tab where you can set it to just back and white

Please note. Not all installers use the proper color codes when they install or replace equipment. It may be necessary go go to the furnace or outdoor unit to verify what wires are for what purpose. Also be sure there are no splices in the wire that could change the wire colors between components.
  • R (red) or Rh (Red heat) 24 volts from equipment.
  • Rc (Red cooling) 24 volts from transformer in cooling equipment.
Note: If only furnace has a transformer and cooling equipment does not jumper Rc and Rh.
  • W (White) sends 24 volts to furnace control to start the heating cycle.
  • W2 (no standardized wire color, usually whatever wire color is available) controls second stage heat.
Note: W2 is most often used for heat pumps to control what is called emegency heat or Auxillary heat, and most often will use the white wire.
  • Y (yellow) often (blue) is used, controls cooling unit (outdoor condensing unit) also is used for heat pump heat.
  • Y2 (no standardized wire color, usually whatever wire color is available) controls second stage cooling.
  • G (Green) controls the fan "on" operation of the furnace/air handler. Also often is used to start the blower for many electric furnaces.
  • C (common) most often brown but can also be black or other color available to installer.
  • O (orange) Energizes heat pump reversing valve for cooling (Trane and most other brands).
  • B (Blue) Energizes heat pump reversing valve for heating (Rheem, Ruud and Weatherking).

Picture is now black and white


 First, confirm that the source is actually in color - try another channel or input device.
Next, check the settings of the color control - it may have accidentally been turned down. If your TV has some kind of automatic picture mode, try turning if off and adjusting the color control. Try adjusting fine tuning if you have such a control and the problem is with a broadcast or cable

  5. Defective chroma chip (don't suspect this first just because it is probably very expensive).
A service manual or Sams', DMM, and scope will help greatly in attempting to troubleshoot this unless it is an obvious bad connection. Try prodding the main board around the chroma chip with an insulated tool to see if you can make the color come and go.

1) Loss of color = bad solder connects on signal board

2) Loss of pix = probable CRT coolant leak onto signal board
Have a technician check it out.....can be expensive......T.

Check the WHITE BALANCE settings and the COLOR EFFECTS settings (marked as W. BALANCE and COL. EFFECTS when MENU is pressed).

When you got to the MENU setting, press up or down arrow until you reached either selection, press the left arrow, and you'll see several options under the selected function. In WHITE BALANCE, there's an option whether you'll be shooting under sunny or cloudy skies, tungsten or flourescent lighting, and an option to select Auto or Manually set White Balance. This affects the over all color tone as it compensates the color correction depending on your shooting conditions. Fluorescent lighting for example exhibits blue spectrum, thus setting White Balance to FLUORESCENT will add warm or yellow tones to the photo. Tungsten lighting and sunny conditions exhibits yellow lighting, and setting to the White Balance on this mode will add cool or bluish tone to the picture.

Same with COLOR EFFECTS: settings include WARM, COOL, SEPIA or BLACK AND WHITE (gray scale).

Chances are, you have accidentally set the WHITE BALANCE or COLOR EFFECTS to any of these. To see if this is the problem, try shooting under SIMPLE MODE (Marked with a HEART icon at the rotary dial on top right of the DMC-FZ7). If the problem goes away, then it is with the WHITE BALANCE and the COLOR EFFECTS settings. Try setting the COLOR EFFECTS to "OFF", and the WHITE BALANCE to "AUTO".

If all else fails, then you got a problem with the image sensor of your Panasonic DMC-FZ7 Digicam
