My sons psp has a black screen


Without a functional screen, the PSP doesn't have much of a purpose. If the power light next to your screen is off as well, all your PSP needs is a good long battery charge. But if the power light is on and the screen is still dark, a few quick troubleshooting steps can help you get to the root of the problem. If troubleshooting doesn't work, you will need to contact Sony eService through its support site, particularly if your PSP has recently been dropped or had liquid spilled on it.
Step 1Turn off your PSP. Remove the battery pack. Replace the battery pack, making sure that it is securely inserted. Turn the PSP back on. If the screen is still black, continue to Step 2.
Step 2Press any system button. If the backlight is turned off, pressing a system button should reactivate it. If the screen has turned back on, go to the PSP settings menu. Select "Power Save Settings." Select "Backlight Auto-Off." This option automatically turns off the screen if the PSP has been idle. If you do not wish to have this feature active, select "Off." If this step did not solve the problem, continue to Step 3.
Step 3Press the screen brightness button below the screen. This button is marked with a small donut-like icon. Pressing the button will incrementally increase the brightness of the screen. Holding down the button will turn off the backlight. It is possible that this button was accidentally pressed down after placing the PSP in a pocket or a backpack. If the screen remains black after the brightness has been increased to full, continue to Step 4 if your model of PSP is any but the PSP Go.
Step 4Open the top hatch on the PSP. This will eject the UMD disc. Only touch the UMD at the edges, as fingerprints can interfere with the disc's functionality. Clean the surface of the UMD with a clean, dry cloth. Do not clean the UMD with water or any other chemicals. If the disc looks scratched or damaged, this is likely the cause of the screen issue. Additionally, moisture can condense on the UMD if the PSP has undergone a recent temperature change, such as being brought into a warm house from a cold car. If the UMD looks wet, turn off the PSP and allow the UMD to air dry. Wait several hours before trying to restart your PSP.

I swiched off my laptop inspiron 1000 at the off switch. when I put it back on the back light did not work


how do you know it is the backlight? Usually people think that's it but it is the inverter.
f the backlight of your laptop stopped working and the image on the screen is so dim that you can barely see it under bright light, most likely you have a failed inverter board. There is a good chance to fix the problem if you replace the inverter board. If you replace the inverter board but the image is still dim, most likely there is a problem with the backlight lamp inside the LCD screen. If that's the case, try to replace the LCD screen. Note: it's much easier to disassemble the laptop display panel when the display panel is separated from the laptop.

I can definitely fix either way if you are out of warranty from dell.

My dell e1404 laptop is having a issue with the screen. When you turn on the computer the screen will come on for about 30 seconds and then go off. When it's on everything looks normal. once it goes out...


The inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. The inverter board converts low voltage DC power (few volts) supplied by the motherboard to high voltage AC power (few hundred volts) needed for the backlight lamp.
When the inverter board works properly, the backlight lamp gets power and the LCD screen lights up. As a result, the image on the screen is bright. If the screen is dimming down, means that the inverter is failing in it;s job to supply the needed voltage to the Backlight.
The Inverter is mounted underneath the display screen and is connected by a two wire plug.

Psp green light on but now screen


Try Holding the R trigger and turn the power on at the same time. This puts you n a diffreent mode, then press the display brightness button to see the version. Power off and back on agin to see if that resets it. This is only a guess I would appreciate at least a thanks for trying.

Oops,... i dropped my psp


Hey Dude,

All things are fixable. Try going into recovery mode. This is done by Pressing and holding the R button when powering up the PSP. You then can press the brightness control button to see the firmware. This might help you reboot the PSP. If it is worst than this, you may consoder sending it back to Sony for repair, although they usually do not want to fix a Squooshed PSP. I would not tell them you Sat on it. You can call SONY support at 1-800-345-7669.
If you cannot get them to Repair it, you can check out my website, www.Playstationclinic.com . I can fix it for a very reasonable price.
