SOURCE: flashing red and green light in xbox

You have a major failure on the motherboard. If it was your hard drive the system will boot up, but freeze on the main screen and you will hear clicking coming out of the hard drive. Red and Green flashing lights means there is a problem on the motherboard. Sometimes you can fix the problem by reflashing the Bios on the main motherboard.

SOURCE: Can't get power to my RoadPro 1500 DC to AC Power Inverter

I have had this same problem with several power inverters over time. The problem is usually one of three things.

Those starting with the simplest.

1. Too much current being drawn on the inverter.
Solution (Check appliances that are plugged in and make sure they are not drawing more than 1200 watts. If they are unplug the appliance that is using the most current and get an inverter that is more suited to your power needs.)

2. Some power inverters have fuses built on to them. Sometimes multiple fuses. Sometimes, one fuse may burn out leaving one intact. When this happens even small items draw too much current and over load the inverter.
Solution (Replace the fuses)

3. Improper installation. Inverters draw a lot of current. You must use the propper wire size for the inverter. I would recomend at least an eight guage wire directly fused and hooked directly to the battery. Of course like with all things the bigger the wire the better the flow of electricity.

If it is not one of those things stop into a truck stop electronics shop and have the person diagnose it.

Hope that helps.

SOURCE: No power output from my vector 1000w inverter.

Buy a different brand of inverter. Yours has developed a short which the protection circuit is catching. It then tries a restart but fails all over again. Most likely o/p short which looks like an overload to the inverter.

SOURCE: Smart UPS 1500 - battery level green lights blink on and off

You need to run recalibration on the unit.  The supplied PowerChute software & cable will allow you to do this if you hook the UPS up to a PC (I know it works with the serial cable, not sure about USB).  If you only have a MAC then I cannot offer a solution other than to buy the standalone PowerView device from APC.  It will cost a bit more than a battery, but may save you from buying needless batteries in the future.  I finally broke down an bought one, but note that I was still having the problem after the 1st recalibration.  By trial and error (and maybe a vague memory) I put my MAC in sleep mode, that dropped the load to stop the lights from flashing.  Then I recalibrated with a 22% load and now it finally seems better (lights no longer flashing).  This was with a Smart-UPS 1000.
Let me know if that helps.

White screen at bootup


Dell Support > Inspiron1564 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/ins1564/en/sm/index.htm

http://www.insidemylaptop.com/replace-broken-screen-dell-inspiron-1564-laptop/

Let's start with two small primers first;

A) An LCD screen cannot produce light. It needs an additional light source. A Backlight is the additional light source.

A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)
The Dell Inspiron 1564 Notebook PC can come with either a CCFL backlight, or LED backlighting.

http://www.laptopscreen.com/English/model/Dell/INSPIRON~1564/


A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

[ Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.
Basic example. Look at the last 9 photos,

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

A screen Inverter is used to convert the electricity from the laptop, for the LCD screen, and Backlight.
For LED backlighting a screen Inverter may not be used.

B) For a Dell, video cable is Display Cable.
LCD screen = Display Panel
Switch Cover = Power Button Panel
(Cover that is a strip of plastic essentially, that is above the Keyboard, and below the LCD screen. Has Power On button)

Display Cable:
The display cable attaches to the motherboard, in an area under the Power Button Panel. (Above the F2 and F3 key, approximately)
It then routes under the left Hinge, and up into the Display Panel Assembly.

From there it attaches to the screen Inverter, if used, and to the back of the LCD screen.
A example of the cable,

http://www.ebay.com/itm/DELL-INSPIRON-1545-LCD-FLEX-CABLE-LED-R267J-NEW-/370491513861?pt=US_Laptop_Screens_LCD_Panels&hash=item564303dc05

The cable may become pinched in the left Hinge. This can cause pulling on the cable, and/or damage.
Pulling may cause loose connections of the cable. Loose at the motherboard side, or LCD screen side.

Doesn't take much of a loose connection to get issues like what you are seeing.
In fact it may be so minute (My-noot) that it won't be visually seen.
The ONLY way to be assured the connections are tight, is to PHYSICALLY check them. Try to plug them in tighter.

This means checking the display cable on the motherboard side, and LCD screen side.

http://support.dell.com/support/edocs/systems/ins1564/en/sm/powerpan.htm#wp1061007

The Power Button Panel contains the Power On button/switch.
It can be removed, and laid over so that the motherboard connection can be checked, with the Power On switch still attached. This way after physically checking the connection, the laptop can be turned on, and display checked.

[Lay the Display Panel Assembly back as far as you can. Suggest covering screen with soft cloth, or suitable device to protect screen.
Screen has to be handled as if it is good, until diagnoses shows differently.

If the Power Button Panel cannot be laid back far enough, to get out of your way, unplug the Power Button cable. Plug back in to check display.
ALL power removed BEFORE disassembly.
Replace Battery, and AC adapter (Charger) when going to test display, after checking connection ]

For the LCD screen (Display Panel) side of display cable connection,
remove ALL power, then,

http://www.insidemylaptop.com/replace-broken-screen-dell-inspiron-1564-laptop/

,disassemble down to Step 7. This way you can lean the screen out, and check the connection.
Display Panel connection physically checked reinstall power, turn on, check display.

IF there is obvious visual signs of damage to the sheath of the Display Cable, there may also be damage to the tiny wires inside.
(Stretched/Broken)

A continuity check with a multimeter is warranted.
If the Display Cable's sheath does Not show obvious signs of damage, it is still best to perform a continuity check, so you can Positively rule out the Display Cable as the problem.
Suggest go to a local 'Mom and Pop' computer store, and for a coupla' bucks have them check it.

Or replace it.

Display cable checks out 5by? (OK)
Go on.

Screen Inverter:
The next item to check is the screen Inverter, IF a screen Inverter is used.
90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.
One example of an Inspiron screen Inverter,

http://www.ebay.com/itm/New-Genuine-Dell-Inspiron-1545-Series-Lcd-Inverter-Board-15-6-H251M-0H251M-/300756244730?pt=US_Laptop_Screens_LCD_Panels&hash=item46067818fa

Yes. It's an Inspiron 1545 screen Inverter. Couldn't find a listing for an Inspiron 1564 screen Inverter. Means to me that most of the 1564's use LED backlighting, or everyone is switching to an LCD screen that uses LED backlighting.

Display Panel:
If the screen Inverter checks out, the problem is the Display Panel.
(LCD screen)
IF there is No screen Inverter used, the problem is the Display Panel.

I'm willing to bet you have a loose Display Cable connection, or damage to the Display Cable.

For additional questions please post in a Comment.

[ For the areas you are going in no ESD wrist strap is needed.
It IS however, always a good practice to wear one, and have it's alligator clip attached to a good ground source.

Electro Static Discharge.
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer. (Laptop or Desktop)
Doubtful that you will see it, or feel it. Poof! Your computer is fried.

An ESD wrist strap relieves your body of Static. You CANNOT just touch a metal frame of the laptop to relieve your body of Static, like you can a desktop computer.

Average cost is around $3 to $6. One example,

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case. I do not feel an anti-static mat is warranted.
You can also set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or use a large metal knickknack (Unpainted ]

Compaq Persario V2000 Black (very dark) Display


Hello Bigkahn, The problem you have is related to the power inverts that powers on a small fluorescent light on the bottom of the actual LCD pannel. The "display" is composed of mainly 2 parts. One is the TFT active matrix that is build up by using many transistors. There are 3 of them for each pixel, each transistor displaying one basic color (RGB code red-green-blue) and 3 of them, like i said, forming a single pixel. They don't produce light by themselves they only filter the light that pass through the TFT pannel. So if a transistor displays "green" it will do that by filtering the light that comes from the fluorescent lamp i was talking before. It produces white light so therefore the transistor pannel will filter the coresponding wave lenght to block anything else than "green". (white light is a combination of all spectrum lenghts) Therefore in your case, if you light up the display using an external light, you may see something on it because the pannel will try to filter the light you give to it. This shows that the actual transistor matrix is working. Your problem is like i said, related with the power inverter. It'a small device inside your laptop that will raise the tension given by the batteries to about 2-3000volts needed to fire up the fluorescent light (some kind of "neon"). If it doesn't work that light woun't come on and the display woun't light up therefore the transistors on the pannel woun't have anything to filter and display on the screen. This problem can happen because of either a faulty connection between the inverter and the fluorescent lamp, or the inverter to the mainboard. Another cause can be the hardware failure of the actual inverter that is preventing it to raise the tension to the specified values. Either of these will require you to have your laptop checked at a service center because we are talking about tensions ranging 2-3000Volts and sensible component. This shouldn't be an expensive repair because the actual pannel (the screen) is working fine and all that needs to be done is to check the inverter or replace some components relating to it. If you have further questions please feel free to reply to this. Good luck.
