Re: HP Pavilion laptop battery life

Maybe your battery aging, battery's life is about a year (I also use laptop)
If you often use external power supply, take out the battery, it will extend battery life, because the battery's life depends on the times of charging and discharging.
You say the screen is brighter, some laptops have a default value of setting LCD screen in computer system, you can adjust the brightness youself. Press "EN" key, and press "upward" at the same time, the screen can be brighter.
Or you can get a replacement battery,
I don't know what's the brand of your laptop, I have bought a battery online, the quality is OK.

When we turn tv on,it will click right off,and shows a stand by timer light. what could be wrong with this? My tv is 10 years old

Hi. I see this type of problem alot, and this seems to always be the problem.

The vast majority of these are due to capacitors either built itno the power supply, or on the main circuit board.
These capacitors work like a booster battery, giving a sudden charge of electricity all at once, that way it energizes the t.v..
These capacitors seem tro be failing alot, probably due to the fact that alot are manufactured in countries where quality standards aren't what they would be if they had been made here in the U.S.

Good quality capacitors should last around 30 years or so, before failure, however, alot of the are only lasting around 1/3 of that time.

Some are only lasting a couple of years, some are lasting 8-10, but all of them are not lasting to their life expectancy.

I would look at your circuit boards, and look for swollen or exploded capacitors.
If they are exploded, they will look like an exploded battery, where it splits down the side.

This is most likely the condition here.

As for repairing, good quality capacitors are not cheap, and can be the difference between getting it repaired and just buying a new t.v.

I hope this is what you were wanting to know.

My HP dv6000 laptop screen goes black suddenly, without warning. It is solid black if on battery power; if I have it plugged in to power supply, it is black with flickering white lines.

Your inverter is failing. Under battery power there is not enough DC power for the inverter to convert to High voltage AC power and it goes black. Even under charging, there seems to be evidence that the inverter is failing because there it is unable to consistantly convert the needed power. Check the cables on the back of the display and change your inverter.

SONY KV32XBR400 (year 2000) screen is blank when power turned on

The clicking you are hearing was probably always there, it's just that when something goes awry, one pays closer attention. What you hear is probably a relay that connects power to the rest of the set. Since our sets can respond to a remote, they always have a little bit of life to supply power to the infra-red receiver so it can respond when 'off.'
I see two possibilities; the relay itself has burned contacts and not always 'closing' as it should, or, the high voltage circuit is failing to turn on as it should causing an excessive current to flow for a moment and a protective circuit to trip and disconnect the power from the main supply.
It probably will get worse if the problem is not found and could damage other circuitry as well.
Good luck finding a TV repair man who isn't deceased or out of business but I do recommend you try to have it repaired. Once repaired, it will outlast most any panel/flat screen-type TV as it appears nearly all of them are failing much too early in life.
You can check by entering just "LCD," "plasma" or "projection" plus TV in the search window here.

Rainbow screen then powers off

The degausser cricuit may be the fault. The degausser coil may be staying on, and thus forces a shut-down. It is also possible to have a power supply fault that can cause a similair effect.

The set will need shop service.

Picture beginning to fail

There are some components it the vertical deflection amplifier area that are becoming thermo sensitive with age. It is also possible that there will be parts going off value in the power supply and other areas.

These problems are typical in these sets when they are aged. The cost of the repair may not be worth the investment.

You should take the set in to a service center for an estimate.

Computer shut off

you have a hardware conflict or a bad power supply/MB. or a bad video card/driver. or a bad RAM chip. uninstall everything but one chip, one HDD and CDROM, and one video card. install the OS rom there... then add items until it becomes unstable. the last thing you installed is the bad boy.

Power problem on a RCA big screen TV

Even with the tv turned off, the power supply is still active.It's supplying voltages to the microcontroler, that's why each time you press the power button on remote the tv respond by turning on. First check the power cord to be well connected in the power-bar and if it's ok...well the power supply is defective and due to the high risk of electric shock i suggest you to call a technicien.
P.S. I respond here because I don't know why our chat session got disconected.

Picture smear and screen brighter on the right hand side

If you know how to read a service manus then what you are looking for is a possible bad cap on the 200v source feeding the video output collectors or video output IC. That is the first suspect.

Will be watching tv and it goes light flshes on front(power)

There sounds like a bad connection, and or a heat related componet breakdown. I have seen mostly on this model number, bad connections on or around the flyback transformer,the horizontal driver transformer, the sweep power supplies, and or the main power supply. If the regulator IC is intermittant, or has a bad connection on one of the leads, it will cause this problem as well. Please if you have no solid state repair experience, seek out a pro to assist you in this repair. Good Luck Please do not forget to rate this thread.
