I wasn't able to find their web site. The suspected website is for sale and I found that the inventor has died. It may be that it is no longer being made under that name.

A 40 W fluorescent lamp gives out more light than a 4o W filament bulb.explain whether the fluorescent lamp is actually using electrical energy at the same rate as the filament bulb??


The lamps are both using 40 watts of energy, but the fluorescent lamp gives more lumens (visible light measurement) than the incandescent.
Fluorescent gives at least 5000 lumens for 100 watts.
Incandescent gives 1750 lumens for 100 watts.
You can see that if you had a 100 watt incandescent, it would be 1750 and you would only need 35 watts of flourescent.

My screen on my laptop just went all black with a very faint image. what is wrong there, how do i fix it, and what made this happen?


A) What is wrong?;
Your Backlight has gone bad, or the Inverter.

B) How do I fix it?
Replace the Backlight bulb, or the Inverter

C) Backlight bulb's, and Inverters, like everything have a 'lifespan'
This one is at the end of it's. (Stating the Backlight or the Inverter

From here all I can give you is Generic information, since I do not have the laptop manufacturer name, and Model Number. This is on the bottom of the laptop.

1) An LCD screen cannot produce enough light by itself. A Backlight bulb, (Or more than one), is used to emit enough light.

2) A laptop cannot produce enough power to power the LCD screen, and is also used for power to the Backlight.

I'll have to discuss the way the Display Assembly is put together, and name parts in order to explain the following of how to repair. Again, generic information.

1a) The plastic top of the laptop is the Top Cover. There are different names used by different manufacturers.

1b) Looking at the LCD screen with the laptop open, there is a plastic frame that goes around the edges of the LCD screen, and is in Front.
This is the Display Bezel

1c) The LCD screen is behind the Display Bezel. The LCD screen is a composite of layers. The outside layer that faces you is a protective screen.
Around these layers composing the LCD screen, is a metal frame.
One side, (Or both sides) of the metal frame is removed to access the Backlight bulb.

1d) The Backlight bulb is a CCFL.
Cold Cathode Fluorescent Lamp.
Very similar to the fluorescent lamps, (Bulbs) uses in residential, and commercial applications, but on a MUCH smaller scale.

Now to show you generic laptop info on replacing the Backlight bulb for them.

A) http://www.insidemylaptop.com/category/backlight/

B) http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

If I had the laptop manufacturer name, and Model Number, I could try to give you a link to the Service Manual for the laptop. (Free. Usually from the laptop manufacturer)
This way you would have Exact info on how to disassemble your laptop's Display Assembly.

My monitor is blank. No power when connected to computer. What went wrong It is a benq model


filmorepetty, The "switch-mode-power-supply" has gone into SHUTDOWN mode because it has detected a fault with itself or another circuit. Or it could have just blown a small fuse on the circuit board of the SMPS. Will the pilot lamp light-up? Did it have a clean, bright, crisp, image displayed on the lcd panel the day before? How old or how many total (approx) "ON" hours of use has it seen? Do you know that 98% of lcd monitors use "cold-cathode-fluorescent-lamps" and an accompanying "electronic ballast" circuit to generate the WHITE LIGHT needed for you to see the pretty colors on the LCD Panel?? Same basic lighting technology as the new screw-in socket curlie-Q CFL light bulbs! Only your monitor's lamps are thinner and straight and hung on the rear of the LCD panel. A failure of the ballast circuit could cause SMPS to shutdown. I suggest you visit some other websites for more info on what other owners are doing to try and repair BLACK SCREEN lcd monitor problems. The first place to go would be YOUTUBE and search and view the longer 6-12 minute video clips of "LCD monitor disassembly" and "LCD monitor repair" just FYI and to know what you are dealing with??? Your unit could also have FAILED electrolytic filter capacitors on the SMPS printed circuit board. I'm 12fixlouie Bye for now.

Our touch sensitive lamp no longer responds to touch


The sensors do not wear out as such, the fault probably is in the electronics and you should not attempt a repair unless you are suitably qualified as mains voltages are involved.
