My 1501 Dell Inspiron turns on but I have a blank black screen. The only light that shows is the power light on the upper right side of the laptop.


Power getting to the laptop. Try first to see if this will give a screen image on an external monitor, listen for the sound of the cpu fan, hard drive and DVD rom drives clicking, see if the DVD rom drive will open if pressed.

Then remove battery and AC adaptor, press the power button for 30 secs, refit mains only and try this on mains supply (no battery)

If this fails to boot, check the light on the ac adaptor is a steady green, flashing green indicates power is not fully reaching the laptop (motherboard problems)

If it is steady and the LED power light on the laptop is steady, suspect the DC jack socket. If this feels loose or sloppy, it will need replacing, depending on the type fitted, it may be soldered onto the board, or a wired connector, which sometimes goes bad.

After that, I'd suggest that a capacitor has gone on the actual motherboard and you will need to strip the laptop to check it.

Hi,


This may cause by an electrical charge in the motherboard itself,Im not really sure how it affects the display of the computer.There's also a possibility that the problem is with the LCD cable or the LCD itself. Please follow this method since it usually fix such problem like that,


1.Removed the battery then unplugged the AC adapter


2.Press and hold the power button or the ON/OFF button for at least 30 seconds


3.Connect the power supply back to your computer then turn it back on.


4. Check if you will see any difference.


5. If nothing happens, try to press and hold Fn and F2 on the keyboard.


If nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...


I hope this information will be helpful. Thank you for using FixYa...

What can I do to fix my hp pavilion tx2000 because it shows a black screen when I turn it on but everything else works fine and it even worked perfect when I connected it to another monitor by vga


You might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

Try an external monitor & see if it will work. If it does, then this might be a sign of a faulty LCD cable or screen inverter board.

Test with an external monitor attached to the laptop. If you get display on the external monitor, then this confirms the case.

jain rajendr, You or electronics technician will need to verify proper operation of your monitor's internal AC to DC power supply first. When very strange things start to appear on the lcd panel, the first place I would look would be the units SMPS/inverter power supply. 12fixlouie

Does a crt need ac supply or dc one? In an lcd there's an inverter to generate an ac signal for varying the power supply to different pixels on a monitor in order to produce different colour effects,does...


Most CRT displays sold for use in the US & Canada (and probably everywhere else for that matter) require AC. This is because AC is the most popular mode as it is easily stepped up for long distance transmission and down for use in commercial, industrial and residential uses, by your local utility. Additionally, AC is affected by losses or resistance differently than its DC counterpart. All of these (and more) reasons reduce the cost of providing electricity to buildings and homes.

If the utility generated and delivered DC, then electrical devices would be set up for DC connections. Since there is 60 Hertz AC at your outlet, the CRT makes use of it, and converts it to whatever the internal requirements are. Stepping the voltage down and / or changing to DC (inside or outside the cabinet) allows for many parts of the circuit to work directly - and AC of nearly any frequency (not just 60 Hertz) can be produced as needed with electronic circuits inside the cabinet.

Colors, shading, etc on CRTs are the result of an electron gun at the back of the CRT. The gun fires electrons at tiny red, green and blue phosphorous targets on the front of the screen. When the target is struck, the phosphorous glows briefly. If the phosphorous is behind a red mask - it glows red (the same holds tru for green and blue). This same process occurs for each of the thousands of colored target on the entire screen, 60 times per second.

This is simplified explanation - there are other parts of a CRT. There are circuits that create magnetic fields the direct the electron both left and right in addition to up and down the screen. Without these circuits, there would be just one dot glowing on the screen. There are circuits for refresh rate, demagnetizing, brightness, contrast and more.

I hope this provided a good starting point for you and found it helpful.

Hello, My Canon CLC 900 is showing E061 after it starts up? Any suggestions?


E000–0061, 0071, 0081


1) Clear ‘E000’. Is ‘E000’ indicated immediately after the power
switch is turned on?
• Be sure to turn off the power switch as soon as you have made the
check.
NO: Go to step 3.


Oil thermistor (TH5), Oil heater thermistor (TH6; short circuit), DC controller PCB
2) Turn off the power switch, and disconnect J6019 from J2209 on the
DC controller PCB. Measure the resistance between a and b of the
following table in reference to the detail code; is it 1 Kω?
Code a b
0061/0081 J6019-B5 J6019-B6
0071/0081 J6019-B10 J6019-B11


AC driver PCB
DC controller PCB
3) Replace the AC driver PCB. Is the problem corrected?
YES: End.
NO: Replace the DC controller PCB.
