The led on the front won't light, and I have power connected, but nothing. Is there a reset somewere?


I am assuming you are trying to power up an installed motherboard, based on the category selection. You say that you have power connected. That means that you have connected the 20 (24) pin main connector and the 4 or 8 pin CPU power connector to the motherboard. Have you connected the front panels controls to the motherboard header? There are connections for the power switch, power LED, HDD LED, reset switch (optional). They must be connected in order for the motherboard to start. THe HDD and Power LED connections are polarity-based, so if you hook them upo backwards, their respective LED will not light. The HDD LED plug is usually red and white with the red being on the positive (+) terminal. The Power LED plug is usually green and white with the green wire going to the positive terminal. The power switch and reset switch wires can be connected either way as they are not polarized.

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

LED Indications

The front panel Status LED provides an indication of

the set's operation and the possible cause of a malfunction.

If an abnormal condition is indicated, perform the

Self Diagnostics procedure.

Self Diagnostics

To activate, press the front panel <ACTIVITY> &<CH

??> buttons at the same time and hold for 5 seconds.

The STATUS LED will then flash denoting a two digit

code.

• The number of flashes indicates the value of the

MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2

second.

• The LED then flashes indicating the value of the

(ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.

Example: If the Error Code is "23", the LED

will flash two times, pause, and then flash three

times.

Table 2-2: LED Indications

Error Codes, descriiptions and the most likely cause of

the error are listed in Table 2-3.

Note: The TV must be in "Shut Down." The LED

will probably be indicating an abnormal

condition. If the TV is switched Off, AC is

removed, or a System Reset is performed, the

code automatically resets to "12" No Error.

See the Error Code Log to retrieve a history of

errors.

Note: Use the front panel buttons, not the remote

control.

Note: If there is no response, the front panel may be

locked by a V-Chip setting. To unlock, press

and hold <ACTIVITY> on the front panel for

8 seconds.

LED Indication Condition

Off Off (standby)

Green Power On

Slow Blink Green Power Off with Timer Set

Fast Blink Green (80 seconds) > Off Power Off (Cooling fan still working, 80 sec)

LED Indication Condition

Red Lamp Failure

Yellow TV Too Hot

Slow Blink Red TV May Require Service

Slow Blink Yellow Lamp Door Open or No Lamp Installed

NORMAL INDICATIONS
ABNORMAL INDICATIONS (For details perform Self Diagnostics Procedure.)

Installed mother to new tower case and pwr sw | hd led | reset | power led connecting to my board is the Intel dq67sw 155 matx motherboard need accurate dir to connect these please help


info found at http://downloadmirror.intel.com/19707/eng/DQ67SW_ProductGuide01_English.pdf
Front Panel Header Pin info for DQ67SW. They should be color coded too. 1 Hard disk LED + orange
2 Power LED+ green
3 Hard disk LED - orange
4 Power LED- green 5 Reset Switch - blue
6 Power switch + red
7 Reset switch + blue 8 Power switch - red
9 Power Out (do not use)
10 No pin
NOTE When connecting individual wires from your chassis front panel to the front panel header, be sure to observe the connection polarity. Positive wires are usually solid color and negative wires are usually white or striped.
There is also an alternative pin header if you have a power wire that uses a 3 pin connector instead of a 2 pin connector. It is the 3 pins just past pin 9, and it should be missing the pin in the middle of the 3 pin block. The pin closest to pin 9 is the power led + and the furthest from pin 9 is the power led -.
if you need clarification, check out page 50 of the manual posted above at intel.com

TRYING TO HOOK UP MU POWER BUTTON NEED TO KNOW


Hi there
The front panel connectors are mainly,
  • harddisk activity connector
  • power switch connector
  • reset switch connector
  • power LED connector
  • speakers connector
  • USB connector
Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.

Wire came loose on pavilion xe 734 that supplie power to hard dir


First of all these wires don't supply power to HDD. These wires are for indicator LEDs on the front
panel of the cabinet. One wire `power sw' is to switch on the system from the power button on front panel. `power led' wire is of the power led on the front panel. All these wires will be connected to the cluster of pins on one corner of the mother board. If you can see it will be indicated & printed near the cluster of pins on the mbd, that which pair of pins is meant for what connector. Try to correlate the names on connector with the print on the mbd.

Power indicatoror


From the manual:

"Attach the barrel tip of the AC Charging Adapter to the AC Charging port of the POWER TO GO® and plug the standard two-prong plug into an appropriate, functioning 120 volt AC outlet. The red Battery Status LED indicator will flash, indicating a proper connection has been made and the unit is charging. The green Battery Status LED indicators will gradually light as the charge level rises. The POWER TO GO® must be charged for approximately 11-17 hours prior to first use. All Battery Status LED indicators will be lit solid (the red indicator will stop flashing) when the unit is fully charged.
