The 14 AWG Positive wire should be connected to one side of a 30 A relay (typical fog lamp relay available at most automotive stores). The relay's other 30 A contact should be connected to the battery positive post via a 10 AWG (up to 6 ft/2 m)

2001 ford ranger , no high or low beam lights

Check the On/Off switch on the dash, steering column, and the steering arm/lever is connected properly and that the lighting cable's are cable connectors are connected and not corroded.
1, To check the Earth: Connect a cable from the earth of the bulb to the chassis/body/ metal part of the car.
2, Using a Test lamp: Disconnect the cable that connects the power to the head light bulb, Connect one end of the test lamp to any one of the connectors at the end of the cable that plug's into the bulb. With the low beam on, only one of these wire's will the light switch turned on will light up the test lamp bulb. If none of the cable's light the test lamp bulb. the problem is in the High beam relay, and possibly the Low beam relay as well.
One Head lamp relay: If one cable show a light in the test lamp, check the earth cable on that lamp.
Two Head lamp relay: If two cable's show a light in the test lamp, check the earth cable on that lamp.
Some of the car's electrical systems use the Steering column as an earth point. Check the switch.
In many cases are what is called Earth return (this means that the positive power (+) is supplied by one wire, and the negative earth (-) is connected via another wire) this is to reduce the problems of the rust effecting the power flow.

I have a Didtal Decorating Instant Light Show WL-D and I can't get it to work!

OL means "OverLoad". the light you are using is drawing too much current. use a night light (7watts) or a 25w bulb in a lamp. I haven't been able to find the max wattage the unit can handle. I am running 3 25w bulbs in a traffic light and it seems ok. when you start the program there is a long pause before it starts. seems like it isn't going to run but after a few minutes it starts. if the OL comes up with nothing plugged in then the unit is bad.

LCD screen flickering

Display Configuration A flickering screen may be caused by the computer detecting incorrect display settings as it starts or returns from sleep. It can also come from changes to the screen resolution settings caused by a new program or update installation. Verify screen resolution before assuming the issue is hardware related. Faulty Inverter Next to the display screen behind the plastic screen bezel is a small component called the inverter, which supplies power to the screen backlight. The flickering indicates the power is not reaching the backlight. To fix the issue, replace the inverter. Faulty Connectors The wires and cables traveling from the display around the hinges and into the motherboard tend to wear at the hinge area. Over time, the opening and closing of the screen causes this wear. The solution is to disassemble the plastic casing of the laptop, reorganize the cables so they have no interference from hinges, or replace the cables and connectors with new ones made specifically for the computer make and model experiencing the issue. b> Test an LCD Inverter An inverter is an electrical device on the bottom of your laptop screen. The job of the inverter is to convert DC electrical current to AC voltage to maintain power to the backlight lamp. If the display on your laptop is dark but working, odds are the inverter or the lamp are at fault. When troubleshooting monitor problems on a laptop, you may need to evaluate the inverter to determine which of the two parts is malfunctioning.

Remove the screen bezel on your laptop. The bezel is the piece of the computer casing that surrounds and protects the LCD screen. To remove the bezel, remove the screws around the screen. Bezel removal method may vary by model. Once the screws come out, the bezel should pop off. The inverter will be under the screen. Attach the positive probe (+) of a multimeter to the pin 1 on the inverter. The inverter has two connections, one on each end. With the laptop screen facing you, look at the left side of the inverter. Pin 1 is the top metal flange pointing to the right. Secure the negative probe (-) of the multimeter to any bare screw. There should be a screw securing the inverter to the laptop that will be perfect for the negative ground connection. Turn the laptop on to test the inverter. Turn the multimeter on and check the multimeter reading. If the display records voltage going to the inverter, such as 19 V DC, the inverter power supply is working. Turn the laptop off. Unplug the LCD inverter connection on the right side of the inverter. This disconnects the backlight from the inverter. Plug a working backlight to the connection on the right side of the inverter. Turn on the laptop. If the screen lights up, the backlight lamp is bad but the inverter works. If the screen remains dark, the inverter is bad.

Usual cause is short cct line out transistor or transformer . That my friend is about as far as one can go using guess work

Soltion No._2
The problem is either the power/inverter board or the lamps inside the LCD panel. if one of the mini florescent lamps fail to start up the inverter section of the power/inverter board senses this and shuts the set off and registers the error. If none of the lamps light up, then the board has to be bad (not all of the lamps can go bad a the same time). These lamps are similar to those in shop lights (just smaller) and eventually they will go bad. When a lamp fails to light up then it could be that stage of the inverter or the lamp. A technician is neede to determine which is bad.Knowing this, here is a way to temporarily over-ride the shutdown, you should do this in a room that is as dark as possible to see what the back lights are doing during the couple seconds they attempt to light up. If it never lights up, then you can replace the board yourself . If it lights up and shuts back off then you need a technician to determine if it needs a new panel or the board.
To over-ride: unplug the AC cord, press and hold the [volume down] and the [input] buttons on the TV keyboard while plugging in the AC cord. hold these buttons until the indicator turns green, then release them. when watch what happens. If the green light never shows then do again (you will need to unplug the AC cord for over 30 seconds between each try).

Blank screen toshiba satellitte laptop


IF, there is no display on the external VGA monitor, you have a bad graphics chipset.

Small primer:
Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The I.C., or chipset used for graphics is a graphics chipset.
Proper name is Graphics Processing Unit, or abbreviated as GPU,

The GPU for your Satellite A15 series of Notebook PC, is incorporated into the Intel 852GM motherboard chipset,

It is Integrated Graphics.

Primer over.

I'm betting you get a display on the external VGA monitor, and your graphics chipset is OK.

Video Cable:
The Video Cable connects to the motherboard, immediately right above the Keyboard, (F9 key), and under the Switch Cover.

Click on the photo in Step 14. The single Red arrow points to the motherboard connection, of the Video Cable.

[ Entire pictorial disassembly guide from start, ]

(Switch Cover is the thin plastic strip, that is above the Keyboard, and below the LCD screen. Has the Power On Button )

From the motherboard the Video Cable loops over to the left Hinge, and up into the Display Assembly.

The Video Cable has a separate cable that goes TO the screen Inverter, and the main part of the Video Cable attaches to the back of the LCD screen.

[ Example of screen Inverter,

The screen Inverter is located behind the Display Bezel, and mounted to the bottom/middle of the LCD Screen Frame]

Repeated normal opening, and closing of the laptop, can cause the Video Cable to be pulled on.
This can cause a loose connection at the motherboard side, or LCD screen side. (Also check screen Inverter connection)

Solution is to PHYSICALLY check, by trying to plug the connections in tighter.

(Yes. Switch Cover is removed, and Display Assembly is opened up, and connections checked.
With LCD screen assembly propped up against the Display Cover; Battery is reinstalled, AC adapter { Charger } is hooked up, laptop is turned on, and display is checked )

Also visually check the sheath of the Video Cable.
Damage to the sheath may mean damage to the tiny wires, inside the Video Cable. (Stretched/Broken)

The ONLY way to be assured that the Video Cable is Not the problem, is to perform a continuity check (OHMs) with a multimeter, Or replace the Video Cable.

Perhaps there is a 'Mom and Pop' computer store nearby.
The tech will check continuity of every wire in the Video Cable.
(NO. Not talking about 'Geeks Are Us. No techs)

[ Click to enlarge photo.
The Motherboard plug connector is on the far Right.
The screen Inverter plug connector is in the Middle
The LCD screen connector is on the far Left ]

I still think it's a loose connection of the Video Cable, or the screen Inverter.

Testing a screen Inverter requires a Sensitive multimeter. Read fairly expensive,

A screen Inverter and an LCD screen are a MATCHED unit ]

An LCD screen cannot produce light,

(Click on the monitor image)

It needs an additional light source.
A Backlight is the additional light source.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)

The Toshiba Satellite A15-S127 uses a single CCFL for a Backlight.

CCFL = Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.
View the last 8 photos for a general example,

Fluorescent lamps, (Bulb) contain MERCURY.
Highly poisonous.
Replacing a CCFL should be performed by a qualified tech.

A screen Inverter is used to convert the power, (Electricity), from the laptop, for the LCD screen, and Backlight.

90 PERCENT OF THE TIME the fault is a bad screen Inverter.

Primer over.

Remember, ALL power removed before working on laptop.
AC adapter (Charger), and Battery.

Changing the LCD lamps

You may follow the below mentioned steps to replace the lamps :

1. Power off the LCD TV. Unplug the AC power cord from the television and the electrical socket or power strip.
2. Locate the plastic or rubber grommets or screw hole covers on the rear edges of the LCD TV. Use an awl or small flat head screwdriver remove the rubber pieces from the screw holes by gently inserting the tool into the hole and prying out the cap. Note that on a few LCD TVs, the grommets or screw hole covers may be on the front face of the unit.
3. Loosen and remove the screws in the holes from which you removed the plastic or rubber grommets. Set the screws aside and keep them together.
4. Remove the plastic shield that protects the input ports on the rear of the TV if the unit has one. To remove the shield, use the awl to pry the plastic tabs loose or remove the retaining screws with the screwdriver.
5.Use the flat head screwdriver or awl to separate the front and rear pieces of the monitor casing. Start on the lower edge of the casing and gently pry the two pieces apart. Work your way around the outer edge of the television and separate the tabs until you can pull the front face off the casing. Remove the front bezel piece from the television.
6. Locate the inverter board below the LCD screen on the TV. The inverter board is small circuit board with wire connector plugs on either side. Disconnect the plug on the right side of the inverter board that leads to the backlight lamp bulb.
7. Use the Phillips screwdriver to remove the screws on the edges of the LCD screen that attach it to the rear part of the TV casing. After you remove all of the screws that secure the LCD screen, place the screen face down on a soft towel.
8. Remove the screws that secure the back light lamp in its track. If the wire leading from the back light lamp to the inverter board uses clamps or ties to secure the cable, disconnect or remove them. Remove the backlight lamp from the TV casing.
9. Insert the new backlight lamp into the track and secure with the retaining screws you removed from the old bulb assembly. Run the wire through the clamps or ties as needed to position the wire plug next to the inverter board.
10. Realign the LCD screen with the screw holes in the rear part of the TV casing. Insert the retaining screws and tighten them. Connect the wire plug from the back light lamp to the inverter board.
11. Replace the front part of the TV casing and snap into place. Reinsert the retaining screws in the holes on the rear of the TV and tighten with the Phillips screwdriver. Replace the plastic or rubber grommets and push them into place securely.
12. Reconnect the AC power cord and plug it into the wall socket. Power on the TV and use normally.

The lamp light is blinking once every 5 seconds. The manual says that " Lamp will not light or light is abnormal"


Panasonic PT50LC13 lamp indicator blinks to tell you the lamp is faulty.

You need to replace the bulb or TY-LA1000 lamp assembly. This link displays all Panasonic TV Lamps and TV Bulbs. This page shows Panasonic lamp location and How to Replace TYLA1000 bulb. TY-LA1000 Bulb Replacement requires the use of a long Philips Screwdriver to reach screws within the lamp cage.

Unplug AC power before removing the lamp and re-install all doors, etc, correctly before starting the TV. Vacuum any visible dust or lint from air vents and lamp area. Do not used forced air to blow out dust, big problems may result.

The user's manual has a description of what the Blinking LED indicators mean.

The light bulbs on the above stove inverter

The actual wattage of the bulb cannot really change anything, perhaps from 10 watts to 30 watts, may, but NOT 25 watts to 30 watts, There simply isn't enough anything to detect if resistance based... I suspect your dimmer is faulty...

The screen was black when turned on but could make out what was on the screen when facing the light

You have 1 of 2 issues...

1.) You have a Bad LCD Bulb.. You can get a replacement LCD Bulb and change the LCD Bulb inside the Display which is cheaper and easier than replacing the whole backlight panel.... LCD bulbs cost around $12 Be careful these bulbs are Fragile and if bent when installing- will break...

2.) You have a failing Power Inverter... this is located just under the screen display panel,, it is a circuit board that the screens lcd bulb plugs into and the display cable plugs into... this inverter board converts the DC power in the laptop back to AC power because the screen needs more power to power the lcd bulb...

Your Problem Is One of These 2 Things... Your Best Bet Is To Test The Power Inverter First - Since It Is The Easier Of The 2 To Replace/Repair
