That LCD monitor has a 3-year warranty.
The lamp should last 50,000 hrs. (HP specification).

Tmy monitor shows the images only for 20 seconds, then it turns black.


Hi hope your monitor issue has resolved. I would suspect the problem is a hardware issue then a software setting. Since the monitor is over three and half years old, if your monitor is a LCD with CCFL back light and had been used almost every day, there may be 3 possible hardware issues. First is the internal power supply, that can go wrong due to heating problem within the monitor, this problem usually cause the monitor to display poor quality picture and may show interference lines on screen prior failure. Secondly, it may be the inverter that drives the back light, which may fail due to the safety circuit kicks in, because it involves with high voltages. Thirdly it may be the backlight itself, which is like most compact CCFL energy saving lamps that flickers or turn itself off when it reaches the end of its service life. This problem usually caused the monitor to show redness or yellowness images prior failure.

All of these can be resolved by qualified electronic repairers, all the best.

The Intelli-Check™ Filter Monitors will indicate replacement of the pre-filter and the

HEPA filter. Depending upon your individual usage (environment and hours used),

you may need to check and replace the filters more or less frequently.

To check Expected Filter Life Usage

When the unit is turned on, quickly press the appropriate filter monitor button. The

pre-filter light will flash up to 3 times and the HEPA filter light will flash up to 4 times,

depending upon how much expected filter life has been used.

PREFILTER:

1 flash = from new, up to 1/3 expected life used up

2 flashes = between 1/3 and 2/3 expected life used up

3 flashes = between 2/3 and all of expected life used up

Remains on = time to check/replace pre-filter

HEPA FILTER:

1 flash = from new, up to 1/4 expected life used up

2 flashes = between 1/4 and 1/2 expected life used up

3 flashes = between 1/2 and 3/4 expected life used up

4 flashes = between 3/4 and all of expected life used up

Remains on = time to check/replace HEPA filter

To RESET Filter Monitor

When the filter monitor light remains on, it is time to check/replace the filter and reset

the filter monitor, if needed. With the unit powered on, press and hold the appropriate

filter monitor button down for approximately 5 seconds until the light turns off.
Depending upon your individual usage (environment and hours

A carpenter was contracted to repair a kitchen for $18000, the work took him 6 hours more than he has estimated and as a consequence, he earned $100 per hour less than he had estimated. how many hours had...


I will try to solve it systematically so it will be easier to understand. Note: The solution involves solving a quadratic equation.

Let amount of hours estimated be x:

Expected rate: $18000/(x hours)

Time spent extra: 6 hours.

Totals hours spent: (x + 6) hours

New rate: $18000/(x+6 hours)

Now:

18000/(x+6) x

The new rate is less than old rate by $100, therefore we can make the above inequality equality by adding $100 to the new rate.

18000/(x+6) + 100 = 18000/x

Solve by cross multiplaction:

(18000 + 100(x+6) * x = 18000 * (x+6)

18000x + 100x(x+6) = 18000x + 108000

Simplify:

100x(x+6) = 108000 (cancel 18000x on both sides)

x(x+6) = 1080 (divide by 100)

x^2 + 6x - 1080 = 0

Solve the above quadratic equation by any method (completing square, factorization or quadratic formula)

x = (-b+-(b^2 - 4ac)^.5)/2a where a = 1; b = 6; c = -1080

x = 30 or -36 (hours cannot be negative so disregard this result)

Therefore x = Estimated time = 30 hours

Check:

18000/30 = $600 per hour x+6 = 36 $18000/36 = $500 or $100 per hour less than estimated

How to check the backlight life of my hp l1706


Claimed life for the lamp is 50,000 Hours, but in real life, no way to tell. You can look here what is failed in the backlight lamps, it can be from worn out (blacken ends is one sign of bad lamps, same as home fluorescent lamp), poor soldering works on the lamps. see pictures here: http://s807.photobucket.com/home/budm/allalbums
What is the problem with your monitor anyway?

E1705 Monitor is black also, but can see this screen fine on tv


You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Backlight Life


Yes by leaving the laptop on all the time you could burn out the laptops back light. Set your power settings to turn monitor off after so many minutes of non use to save this. Further more I would recommend a chill pad under the laptop to help keep the CPU from getting to hot.

Backlight is acting like a bad flour. tube .. everthing else OK


Normaly the backlights have a life of around 40k hours of working.
If your monitor is 3-4 years ,the backlight tube/s could be defective.Your description seems to indicate tube aging.

It's possible to replace the tube but needs a good amount of technical skill.
Do write if you need more help,Please indicate make exact model no etc.

Make sure your VGA cable is seated properly. If it is seated OK, it could be the start of a problem with a backlight. When a backlight goes bad, it typically shows up as pink/red color where white should be displayed.
