Re: Dell Monitor comes on but no picture
The monitor isn't getting a signal from the computer, which is why the power indicator goes orange. There are two possibilities:
1) The computer isn't operating correctly. It may not be starting up at all when you turn it on, and you have a "no boot" problem to solve, or
2) The computer is working properly, shows all the signs of normal startup (hard drive activity, Windows startup sound from speakers, etc.). but video isn't reaching the monitor. There may be a problem with the video card (or on the system board if it's integrated video). Or the monitor itself is bad and not detecting the video. You can test this by connectng a known good monitor.

I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?
Let me know what happens with the testing above or if you need further instructions to carry out testing.
What color is the power light when the system shuts off?
Red: If the power light is red, or flashing red, when the system turns off, then the system's battery needs to be charged.
Blue: If the power light is blue when the
system turns off, then there appears to be a problem with the system and
it will need to be repaired.
If the orange recharge indicator light blinks while the system is
plugged in and charging, then it is likely that the battery is not
If you have ensured that the battery is installed properly but the orange
light still blinks, check to make sure that the battery is a licensed
by Nintendo. The only licensed Nintendo DSi battery will have the model
number "TWL-003" (Nintendo DSi) or "UTL-003" (Nintendo DSi XL) and will
display Nintendo's logo. Call 1-800-255-3700 if you still need help.
This is a common problem with many LCD monitors. The printed circuit board that provides a stable voltage for the monitor to operate from starts to fail. The PCB can be replaced, when/if they are available, or repaired in most cases at a much lower cost. for more information on this email me at [email protected]
Since it sounds like an issue with the Power first try to release flea power.Disconnect the charger,remove battery,press and hold down the power button for 30 seconds.Reconnect the battery and charger.Turn on system and check if it turns on. For further help please check Dell Inspiron 1525 Manual. Also confirm if the light on the charger stays on,when connected to the system.
First--was it working? Did it suddenly stop? When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen. So--if you are getting a signal, you should see something. If there is no signal, then the power light should change from green to orange. With no lights at all, I suspect a faulty monitor.
This is general LCD monitor advice. I don't know your specific model. Your problem, however, is very common on many different monitors.
In 90% of cases, the problem is one or more failed electrolytic capacitors on the power supply board. They are a simple matter to replace, but require desoldering the old ones and soldering in new ones, as well as general electrical/electronic safety practices.
If what I've just said already makes sense to you, then you're probably qualified - go ahead and replace them. If I'm talking greek, then go find an electronics nerd - some goofy looking guy wielding a soldering gun should do.
