Green lite comes on for about 2 to 3 seconds then shuts down red lite pulses

The set will stay in ready mode, but when I turn the set on, the green lite will come on, on both the receiver and the monitor, but in about 2 seconds the green lite on goes out on the monitor only, the red lite comes on and pulses.

If the back was off the board on the left is your Ysus board. It will have a cable plugged into the right side of the board from the signal board. Unplug the the Ysus board. If it stays on without a picture change both Y and Z sustain boards. If this helps let me know.

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

Ds lite flashes on but fuses are ok


One or both your screens have blown.

Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.

Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)

If this happens the problem is then you're top screen which you will have to replace.

GREEN ON LITE COMES ON, BUT EVERY FEW SECONDS THE RED STANDBY LITE FLASHES, THEN THE GREEN LITE COMES BACK OM.


Sounds like the power supply. The supply checks for all the various voltages to be there - if they are not it shuts down. It then tries again. So if you are hearing the click in/out of the PS relay that's where the trouble is. Before buying another PS at least disconnect the Ysus and Zsus suppy lines to make sure they are not pulling it down. If they aren't - it's the power supply. It's a complex board (PKG-4014) and if you ever get a diagram I love a copy - they are never in the manuals. Mine was one of the 3641 regulator chips. Hope this is of some help.

Starts to power on,then shuts down


Have you checked the filters? I have a Sanyo PLV-75 and had a similar problem.  The normal fan would come on when the unit was first started, then after a few seconds the secondary fan came on and then the unit would shut down.  Called tech support and they asked if I had cleaned the filters. I did it, and it worked great.  Check the manual for where the filters are and hit them first before getting a new bulb.  Hope it helps!

SCreen turns red then shuts off


The 46H84 has 3 CRTs instead of a lamp. Red, Green and Blue. Your red CRT is shorting out shutting down the set.Here is how you test that theory. Remove the speaker grille, there will be an access panel behind the grille remove that and you will see the CRTs red is usually on the left. hit the power momentarally to locate which tube is red. then power down and unplug the power cord. Carefully remove the tubes Circuit board. ( you may have to carefully slice the glob of silicone applied at the factory to get the circuit board off) Once you have the circuit board off the Red CRT make sure it isnt touching anything and try powering up the set. If the set stays on and the other 2 CRTs light up. That tells you the RED crt is shorted and thats whats shutting your set down. Let me know if I can assist you further.
