Although newer fluorescent fixtures have built-in starters or no starters at all, most older lights have an easy-to-change, visible starter. It is a small, silvery cylinder that plugs into one of the tube holders. 1) Shut off the switch. 2) Remove the tube. 3) Give the starter a quarter-turn in a clockwise direction, and pull it out. 4) Plug in new starter, giving it a quarter turn counterclockwise. 5) Replace tube. 6) Turn the switch on.

Replaced the Florescent and Starter on G10Q Circular T9 Globe. Still not working.

Are you sure the replacement tube is a good one? If it had a shaking in transit it could be internally damaged.

There is two basic circuits; one uses an electronic inverter to produce the high voltage necessary to ionise the gas in the tube and the other uses a choke and starter.
The lamp has a heating filament and a cathode at each end. The starter closes a series circuit that includes the choke, starter and filaments. The filaments will glow and heat the cathodes for a predetermined time when the starter will break the circuit and the sudden collapse of the magnetic field in the choke produces the high striking voltage necessary to ionise the gas in the tube. Once a current flow through the tube is established the choke limits the peak current.

Troubleshooting a conventional fluorescent lamp circuit usually begins with testing the tube filaments for continuity and working back through the circuit...

What is the function of a fluorescent starter

A fluorescent bulb in the old days had a filament on each end that required a heating current to be applied. The starter would allow this current to initiate the heating of the filament and then it would open and allow the bulb to light. The old ballasts where not able to do both functions and the starter kept the ballast from burning out because it limited the current draw from the filament.

Under-counter fluorescent light wont turn on without multiple attempts and then turns off spontaneously after a bit.

If it is really a bulb not a tube, the starter is usually part of the bulb base. Starters don't do anything once the fluorescent tube (a bulb is just a coiled up tube) is lit and running.

With those symptoms I'd say Ray is correct, both need replacing.

Fluorescent light proplem

Hello there,

Ballast can be resistor , capacitor, Inductor or all three.in the older ones, there was a 'starter' (neon bulb inside)

Go here for explanation.

How to retrofit fluorescent tube with led tube lights

Note:
First, corrosive or solubility chemicals will destroy the protective shell of lamps.
Second, the normal ambient temperature is -20 ° C to 40 ° C, if beyond the scope of this provision, it will make adversely affect on the lifespan of the product.
Third, before installing, do not connect high-voltage power supply, if there is damage to the external of lamp, switching to the engineers with qualifications for the repair and replacement; otherwise,the bulbs can not be replaced; take care of the the discharge of fire and shock.
Replacement Procedures Information:
First, the LED tube is generally a double-ended conductive LED lamp containing professionally designed built-in power supply, which can be directly input voltage AC100-240V,it can be mounted directly on a dedicated LED T8 tube light shelves, do not need to add other drives.
Second, the LED tube can directly replace fluorescent tubes, the user can remove the original fluorescent tubes and install LED tube, then double-check the configuration of lighthouse, following the figure A, B, C three installation diagram for installation.
Third, cut off the power for the installation, repair, maintenance and demolition work to avoid accidents.
Installation Guide:
led-tube-light-installation-instruction.jpgA, connect the power cord on the lighthouse to the external power lines, no need to distinguish neutral wire and line of fire fit with LED lamps , then rotate 90 °,then connect the power to light up.
B, if there is starter on light house , take out the starter, then just repeat the A

I need to replace the fluorescent panel starter in my flat panel monitor

The problem is not with the Fluorescent Backlight of the Monitor, it's the Capacitor! Replace the Capacitor on the Power Circuit Board of the Monitor. The Capacitor will be slightly bulged! Use the same ratings of the dead Capacitor like it's Volts and Micro Farads. After adding the new Capacitors your Monitor works like new one. Enjoy!

We have fluorescent cove lights in the living room. We think the "starter" is bad, but we can't locate the "starter". Can you help? We have tried switching the working light bulbs...

Very few flourescent lights have "starters" these days. If it does have a starter, it will be a visible cylindrical object usually located at either end of the fixture. More likely it's the ballast that is bad. Turn off the power and remove the cover to the fixture. The ballast will have a lot of wires coming out ot it. Take note as to where all the wires are attached, remove it, and take it to a hardware store or Lowes or Home Depot to get a replacement. Make sure it is an _exact_ replacement. Sometimes it's easier and cheaper just to replace the entire fixture as some of the older ballasts are expensive due to there being replaced by newer technology.

Fluorescent light that keeps flickering

The ballast is a device that utilises and expanding/contracting electromagnetic field to create the high voltage which is needed to run fluorescent lights.

It is normally found behind the front cover or reflector part of the fitting and looks like a small box.

Replacement should normally be done by a person qualified in this field.

When to replace

Inside a fluorescent light, electricity is delivered to a ballast, which sends a spark through the mercury-vapor-filled tube (or bulb), creating light by activating phosphors that coat the inside of the tube. If any of the components are faulty, the light won't work right. Once you pinpoint the problem, most fixes are very easy. Remember to turn off the power first! Old bulbs blink off and on just before they die; repairs are often simply a matter of replacing the tube or bulb. This problem may also be occurring because of poor contact between the pins at the ends of a tube and the tube holders. If the pins are bent, use needle-nose pliers to straighten them. Clean up the pins and socket contacts with fine sandpaper, and brush away residue. Though gray bands at the ends of tube are normal, black bands indicate that the tube needs to be replaced. If only one end is dark, turn the bulb end-for-end. If the tube is new and these fixes don't work, you may have to replace the starter or ballast. Some fixtures ("A-rated") are quieter than others are, but most fluorescent lights have a slight hum. If the sound seems too loud-- or if you can smell electrical burning-- shut off the power. The ballast is probably either the wrong type, improperly installed, or defective. Replace it or call an electrician. Brand new tubes tend to flicker, as do bulbs that are cold. If an old tube still flickers after it has had a chance to warm up (or after you've warmed up the room), rotate it a couple of times in the tube holders. Try cleaning the tube's end pins. If it still doesn't work, replace it. If only the ends of the tube glow, either the starter or the ballast is defective. Replace the starter, then the ballast.
