SOURCE: I have a monitor HANNS-G

This is a problem with the power supply unit inside the monitor, there is no easy way out here. If you keep on using your monitor like this eventually it won't switch on no matter how long you wait. Keep on using it like this for the time being without switching off anything but ultimately you will have to take it in for repairs or otherwise purchase a new screen..

What does a blinking orange light on 65" Mitsubishi dlp rear projection TV mean?

Self Diagnostics

The V18 Chassis features Self Diagnostics to aid in troubleshooting problems that may cause the set to

automatically turn off or "shut down." The "Timer/Power ON LED" provides an indication of the sets operation,

and the possible cause of a malfunction.

1. Initial Control Circuitry Check

Immediately after the TV is connected to an AC power source:

• The LED flashes three times ... indicating the Microprocessor has initialized and is functioning


• If the LED does not flash ... the Microprocessor is NOT functioning.

2. Error Code Operational Check

To activate the Error Code Mode, while the set is OFF, press the front panel "INPUT" and "MENU" buttons

at the same time and hold for 5 seconds. The LED will flash denoting a two digit Error Code.

Note: The Front Panel buttons must be used, NOT those on the Remote Control.

• 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 LSD (ones digit) of the Error Code.

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

Example: For Error Code is "24", the LED will flash 2 times, pause, and then flash 4 times.

3. Error Codes

The Error Code designations indicating a malfunction, or no malfunction, are listed below:

"12" ... indicates no error has occurred.

"21" ... X-Ray Protect circuit.

"22" ... Short Protect circuit.

"23" ... Horizontal Deflection failure.

"24" ... Vertical Deflection failure.

Forgot the combination to the lock. Is there a way to retrieve the combination or return it to its factory default combination 1, 2, 3, 4, 5

The instructions below are copied from the programming instructions (page 11):

(The "out of box" factory default will be restored)
1. At the back of the lock, remove the screw at the bottom of
the lock housing and remove the cover.
2. Take out the battery pack and remove battery power by disconnecting
the battery pack.
3. Plug in the (provided) male shunt connector into the yellow
wire female connector.
4. With shunt connector connected, re-connect the battery
pack. The lock will immediately sound 3 short beeps (if
these 3 beeps are not heard, then restart at step 2).
5. The lock will then sound more slow beeps, 1 beep for every
second it takes to clear the memory.
6. After a few more seconds, the LED will slowly alternate between
flashing red and green--disconnect the yellow wire
shunt connector.
7. The LED will continue to slowly flash green and red for 25
seconds. To enroll Function Cards, proceed immediately
as follows:
• With the lock LED slowly alternating between flashing
red and green, present the Function Card #1
to the lock. The lock will sound 5 slow beeps.
• The lock LED will flash green rapidly. The lock is
ready to enroll the Function Cards.
• Re-present Function Card #1 to the lock. The
lock LED will flash green then red, with two beeps
(indicating the card was enrolled successfully).
• Present Function Card #2 to the lock. Again, the
lock LED will flash green then red, with two beeps.
• Continue to present, in order, Function Cards 3-
9. Each time a new Function Card is presented, the
lock LED will flash green then red, with two beeps.
After the 9th Function card is presented, the lock LED will flash
green twice, sound two beeps, and will then remain silent,
ready for use. Note: If the lock continues to beep after presenting
the 9th Function Card, check to verify that the yellow
wire shunt is disconnected.
Note: If you only wish to use the first 3 Function Cards, simply
allow the lock to "time out" after 30 seconds.

Nissan pulsar 1987 n13 the ECM light came one and the car cut out and won't start again and I need to know where the ECM is

Hi, the computer is under the passenger's seat. Code extraction procedure is pasted below.

READING CODES Modes will not switch while the engine is running. The ECM automatically switches to MODE I when the ignition is switchedOFF.
1984-90 Vehicles With Dual LED System
The self-diagnostic system has 5 modes. To switch modes, switch the ignition ON and use a screwdriver to turn the mode select switch through the access port on the ECM. The inspection lights will begin to flash. When the desired mode has been entered, turn the screwdriver fully counterclockwise. The red LED and green LED perform different functions in different modes.
Mode I-
This is the normal vehicle operating mode. The green LED will indicate loop status. If the green LED is not blinking when the engine is running, the vehicle is in open loop, or the HO 2 S, O 2 S, or sensor circuit has a malfunction. If the green LED is blinking, the vehicle is in closed loop. If a malfunction takes place, the red LED and the MIL will glow, indicating a malfunction has occurred.
Mode II-
Both the red LED and green LED are used to monitor mixture ratio feedback control. The green LED will function as described in MODE I. If vehicle is in open loop, the red LED and green LED will remain on or off. In order for results to be valid, vehicle must be in closed loop. In closed loop, the red LED remains off if the system is running rich, comes on if the system is running lean, and blinks at the same time with the green LED if system is within 5% of the exact air/fuel ratio.
Mode III
-When this mode is accessed, the codes stored in the ECM's memory will be flashed by the green LED and red LED on the side of the ECM. The red LED will light first. This is the first digit of the trouble code; the green LED will flash next, showing the second digit of the code. For example: 2 flashes of the red LED followed by 1 flash of the green LED corresponds to Code 21.
Mode IV-
This mode is used for checking the throttle plate (TP) switch, starter, and vehicle speed switch status. When the TP switch or starter switch is activated, the red LED will briefly flash as the status changes. For VSS status, the green LED will remain off when vehicle speed is less than 12 mph (19 km/h) and come on when vehicle speed is greater than 12 mph (19 km/h).
Mode V-
This mode represents a real-time diagnostic test of the crank angle sensor, ignition signal and the mass airflow signal. The malfunction code will be displayed only when the malfunction occurs and will not be stored in memory. The output code will appear as a single or short string of pulses. Count the number of pulses for the malfunction code.

1 pulse-CMP sensor signal lost or noise in signal 2 pulses-MAF Sensor signal abnormal 3 pulses-Fuel pump circuit shorted or open 4 pulses-Ignition signal lost

entering a 5-digit User Code.
3. Comes ON in the Program Password mode after you have
entered your User Code and remains ON until you have
entered a 5-digit password.
Yellow LED
Indicates low battery and will typically not turn ON until
battery has been in use approximately two years or longer.
Your electronic lock automatically performs a low battery test
during each lock use.
If a �low battery� condition is detected the Yellow LED will
come ON and remain ON during each subsequent lock
operation. (The lock will continue to function in a Low Battery
state, until battery failure.) The Yellow LED will turn OFF only
after three consecutive Good Battery readings or after the low
batteries are replaced. (Note: If the new batteries are installed
in less than 60 seconds the Yellow LED may come ON and stay
ON during the first lock operation before it returns to OFF.)
NOTE: It is recommended you replace the batteries after two
years, or when the yellow LED remains on.

I have a Mitsubishi WD-62525. This morning my TV would not turn on so I pressed the rest button. After the Timer light stopped blinking I pressed power. I could hear the fans start than a somewhat loud...

the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• 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 LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.

and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure

Picture and sound problem at 21" sony waga color tv

This is due to problem in deflection area and power supply section malfunction. Make one general service by technical person immediately to avoid major transformer failure problem. Since this is initial stage, the cost of repair is probably less.
