Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

Lost my dash light on my 1999 grand marquis


Probably a problem with the LCM - lighting control module . The main light switch is a input to the (LCM) . Here is free wiring diagrams http://www.bbbind.com/free_tsb.html Enter your vehicle info. Year , make , model an engine size . Under system click on lighting , under subsystem click on insturment panel lamps . Click the search button then the blue link . Do you know how to test PWM ,this is how the LCM controls the lights .
Pulse-width modulation Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors an lighting .

No fuel injector pulse


Does the check engine light come with the other lights when ignition is on? Have you checked for power on the injector harness? (Computer supplies ground) If no power possible main relay or fuse issue

Why am I nit getting a pulse to my injectors?


.

OBDII Problem related to the computer controlled system not sending a signal to the positive injection banks. Could be cam or crank sensor problem as well. These systems works on Ohm resistant's and the introduction of a 12 volt tester could compromise the system.

My almera 1.6 2004 model coils not recieving power.


ok, i will try and help you as much as i can. first you should be getting 12 volts a pulse and a ground( negative ). if you're getting the 12 volts and the grounds but no pulse the the car has 2 sensors, one is the cam and the other is the crank. those sensors provide pulse to one for the injectors and the crank is for the coil packs. you can test for pulse by using a noid light or the normal test light. just connect the test light to 12 volts terminal and have someone crank over the engine. if you don't get a low flickering light then you neeed to change the sensor

Truck shuts off while driving


Check the fuel pressure with a fuel pressure gauge, when the truck stops See if the fuel injectors are getting a pulse with a niod light plugged into the harness "while cranking. motor". IF you get no pulses (NO flashing noid light) see if the security light is ON, on the dash. If the security system "kicks on" it will kill the pulses to the injectors.

2001 Acura mdx abs light stays on. Code reads 04?


I think you pulled the code incorrectly, or are reading it wrong. To get code:
1. Jump pins 4 & 9 on OD2 connector.
2. Turn key 2 clicks.
3. ABS light should blink to give you code. (long blinks for first digit, short ones for second. Example: One long blink and three short blinks would be 13).
Honda ABS trouble codes list :
11= Right front wheel sensor (open/short to body ground/short to power)
12= Faulty right front wheel sensor pulse signal
13= Left front wheel sensor (open/short to body ground/short to power)
14= Faulty left front wheel sensor pulse signal
15= Right rear wheel sensor (open/short to body ground/short to power)
16= Faulty right rear wheel sensor pulse signal
17= Left rear wheel sensor (open/short to body ground/short to power)
18= Faulty left rear wheel sensor pulse signal
21= Continous Operation (chipped pulser)
31-38 are all the same: "solenoid"
51= Motor lock
52= Motor stuck off
53= Motor stuck on
54= Main realy stuck off
61= Ignition voltage
81= CPU (central processing unit)

No injector pulse on daewoo nubira i change computer box but still no pulse wot must i look for or replace


Check for an injector fuse in the fuse box under hood. Pull off one injector connector and use a testlight to check for a steady power signal on one of the two wires, with key on. Should have power on one wire. If not, pull all injector connectors off and check again-a shorted injector can shut down the injector drive circuit-if power now, reconnect injectors one at a time. If one connection causes power to be lost, that is a shorted injector. Replace it. If still no power and fuse is good, you will need a wiring diagram to check injector drive circuit.
If you have voltage at the injectors with key on, move the test light ground lead to the battery positive post, and put the test light probe on the injector wire that did not light the test light. Now have a helper crank the engine over-you should have a blinking light on this ground circuit. If no light, or light is not blinking, the ground circuit between injector and computer is bad. See? Steady power is available to injector anytime key is on. When the computer internally grounds the injector circuit for a split-second, the injector is energized, causing the pulse.

My injectors arent pulsing on my 1989 k1500 suburban. I have 12 volt power to the injectors and have replaced the module in the distributior. Any one have an anwser for me


The injector ground circuit must not be working. What causes the pulse is when the computer internally grounds the injector circuit, power is passed across the injector solenoid terminals. All the injector grounds are spliced together on each bank of engine, and run into the computer. So, injector power, but no pulsing would seem a computer malfunction as long as the ground wires are good. Did you check all the injectors for pulse with the noid light, or at least both sides of engine?

Turns over but wont start i got fire and fuel to the fuel rail but the injecters are not delivering fuel any ideas whats wronge


sounds like u got no injector pulse comin from ecm.we need to pull ecm codes an review them ,possible camshaft sensors faulty they usually provide reference pulses to ecm for injector firing or pulse.without this pulse ur injectors will never open up to let fuel enter combustion chamber. one way of checking pulse is to connect a noid light(small light bulb that plugs in injector pigtail to chek for power to injector and ur pulsing ground coming from ecm to injector) an test for a blinking light while cranking engine.

I have the SSC-1500A battery charger and the yellow light keeps flashing. The yellow light is the charging light.not sure why


This unit will assume a battery voltage less than 1.5 volts means the battery is sulfated. The flashing yellow light means it has gone into 'desulfate' pulse mode using pulses of high voltage to try and convert the lead sulfate back into sulfuric acid and lead plating. It will do this for about 8 hours on the charger I have. If the voltage has not raised to a level that can can accept a normal charge it will abort the pulse mode and stop trying to charge it. You will need to unplug and replug in the charger to try again. Always check the temperature of the battery while charging it and especially if the charger is in pulse mode. Stop charging if the battery is hot. *always wear safety gear*
