    I'm sorry I did'nt get back to you sooner, but I'm having problems with my internet service.The switch is one that allows the bottom light, the top light, or both lights, to come on.The switch is on the top bulb socket, I wired it the way you said and it works,

    but it turns on the top light or both lights,the bottom light does not light by itself.The new cord is polarized could this be the problem?

From one side of the lamp cord, to one side of the switch.

From other side of switch to both blacks from the upper and lower bulbs.

From other side of lamp cord, to the white coming from both bulbs.

This assumes there is a black and white wire coming from both bulbs.

Please note, look at the lamp cord closely, particularly the plug. If one prong is wider than the other, then the plug is polarized, and you need to pay special attention to the wires leading out of the plug. One of the two will be ribbed, the other smooth. Note which is on the same side of the plug as the wide prong. Whichever is with the wide prong, should NOT connect to the switch, but to the whites coming from the bulbs.

    John,

    Is the switch function one that allows the bottom light, the top light, or both light's, to come on?

    If so, one terminal is for the bottom bulb, one is for the top bulb, and one is for one side of the line cord.

    The other side of the line cord will be tied together with the remaining wire from each bulb.

    I've not seen a 3 terminal bulb socket/switch combination. If this is what you have, I would think that the line cord terminal would be marked in some way, like the screw is a different color, or there being a marking of some type. Regardless, you will not hurt anything by connecting it wrong, as long as you have the other side of the line cord connected only to the remaining wires coming from each of the bulbs.

    Let me know what you find and I will be happy to help more.

My tornado lava lamp doesn't work. A little plastic piece just bounces around on the bottom.


It's difficult to say based on your limited description. A lava lamp is a first of all, a lamp. Does the incandescent lamp light up? If not, replace it (it's the heat source which creates the swirling action in the attached "lava" globe). As for the plastic piece, perhaps it's part of the lamp-holder socket that broke off due to heat. Perhaps part of the switch.
In any case, the light light bulb probably burnt out. Believe it a standard 40 watt bulb, but be absolutely certain to check before replacing as you do not want to put a bulb with a higher wattage in there due to the confined space inside the lamp.

Tip

Before buying a projector bulb


1. Always be aware of bulb usage hours: bulbs normally last ~ 2000 hours

2. If the bulb pops and goes out:
  • Follow the manufactures safety instructions for this condition.
  • Normally, the bulb will need replacing.
3. If the lamp just turns off:

a. If lamp hours were getting high and the picture was getting progressively dimmer, normally the bulb will need replacing.

b. If bulb hours were low or a few hundred hours from 2000:
  • Clean all filters and air ports.
  • Try the projector again checking overall projector ventilation.
  • There is a heat sensor in most projectors that will shut off the machine if it overheats, so air flow must be unobstructed.
c. If ventilation does not solve the problem:
  • Take out the lamp, following the manufactures instructions.
  • Inspect the lamp bulb visually through the lamp glass window.
  • Look for cracks or damage in the bulb and whether one or both of the lamp wire elements is detached from the top of the bulb.
  • In either case, the bulb is bad and should be replaced by purchase or possibly by warranty if the lamp hours are low.
  • Normally, bulb replacement is the solution, but other issues could also exist.
d. If the lamp looks undamaged and/or you are unsure of the status, the problem could be a lamp ballast, power supply, or main control board issue, and should be evalulated by a technician. Unfortunately, a bad bulb can also result from one of the above issues.

Removal of burnt out bulb in ott lite


Depending on lamp the bulb is approximately a 1/8 turn with a slight push toward the base to release the bulb, If you have not purchased the replacement bulb take the old one with you, some "high end" lamp stores will have replacements, if not the website will help. Good Luck!

What is the process for replacing the headlamp


Replacing headlamp bulbs
Handle a halogen headlamp bulb carefully
and keep out of children’s reach. Grasp the
bulb only by its plastic base and do not touch the
glass. The oil from your hand could cause the bulb
to break the next time the headlamps are
operated.
If the bulb is accidentally touched, it should be
cleaned with rubbing alcohol before being used.
To remove the headlamp bulb:
1. Make sure headlamp switch is in OFF position,
then open the hood. If you are replacing the driver
side headlamp, unclip the electronic module on the
right side of the battery and move it out of the way.
2. Locate the headlamp bulb through the hole in the
upper radiator support assembly.
3. Release clip and
disconnect the
electrical connector
from the bulb.
4. Remove the bulb
retaining ring by
rotating it
counterclockwise
(when viewed from the
rear) about 1/8 turn to
free it from the bulb socket, and slide the ring off
the plastic base. Keep the ring to retain the new
bulb.
5. With out turning, remove the old bulb from the
lamp assembly by gently pulling it straight out of the
lamp assembly.

To install the new bulb:
1. With the flat side of
the bulb’s plastic base
facing upward, insert
the glass end of the
bulb into the lamp
assembly. You may
need to turn the bulb left or right to align the
grooves in the plastic base with the tabs in the lamp
assembly. When the grooves are aligned, push the
bulb into the lamp assembly until the plastic base
contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base
until it contacts the rear of the socket by rotating
clockwise until you feel a “stop.”
3. Install the electrical connector into the rear of the
plastic base until it snaps, locking it into position.
4. Turn the headlamps on and make sure they work
properly. If the headlamp was correctly aligned
before you changed the bulb, you should not need to
align it again.

Touch lamp repair


Double check that the replacement bulb is good. If it is, then when the old bulb blew, it probably shorted and destroyed the touch sensor. The touch sensor is replaceable and is usually located in the base of the lamp. You may have to peel off some felt on the base to expose the screws that hold the base on. Touch sensors are generally available at hardware stores, electrical supply stores, or lighting stores and are around $10-15. They are easy to wire. Just follow the instructions and observe the way the old one was wired. You may need some small wire nuts if they don't come with the new sensor.

XL-2100U lamp cycles on and off


Hi

I recently had a similar problem after replacing my lamp the set would work for 22 mins then go into standby for 30 sec then come back on, then repeats, I decided to experiment with the lamp housing, I removed the new lamp, unscrewed the top of the lamp that holds the actual bulb then switched out the main housing (bottom part) with the original housing, that seemingly has corrected my problem, you may want to try if the replacement lamp did not come from Sony...good luck
