Mostly due to ram or system board as you suggested. In case your product is still under HP warranty, I will suggest you call them, They will fix it for no charge.In case you are out of warranty, contact them anyway since they fix out of warranty PCs in case the problem is due to a defect they know about.

How do I fix 'out of range' problem when I connect monitor to my MacBook Pro


Check to make sure that closing the panel down does not cause the laptop to go into standby or suspend mode. In other words, are you sure that the video signals are not halted by the action of closing the panel down?

LCD screen black


Desktop Windows Manager, is the one who's giving the fancy effect on your screen. try to boot your computer under safe mode by pressing F8 upon reboot. by then, you can only access the system and check the program status.

thanks

Samsung n120 netbook screen remains black through windows boot up. I'm assuming boot up into windows then home page goes ok, because I can hear the windows start up music, then eventually skype...


Hi possible the Video card is busted on the LCD, get in BIOS see if the screen will still remain Bak if it does then the LCD is busted, get in safemode if the issue is still the same then it is the LCD but if there is Video in safe mode the issue is the video card
To get in safe mode keep on tapping F8 as soon as you power the Laptop To get in BIOS keep on tapping Del or F1 as soon as you power the Laptop

Red white and blue straight vertical lines are appearing on the lcd


Jose,
The lines indicate that the resolution of the LCD is not matching that of Windows. You have over done the resolution. What you do is that reboot and press F8 at boot up before you see Windows booting. A plain black and white Menu would appear. Here, select Safe Mode. Once booted in Safe Mode you must right click on the desktop and select Properties->Display Settings. Here reduce the resolution of the LCD by one notch at a time till you get the correct display.

My 15" LCD monitor TTX went to sleep mode and never return back


mike_garzan, Your monitor will need some work done on it!! Do you know the "flashlight trick" that every owner of an LCD monitor with "cold cathode-fluorescent-lamps" should know how to do when the BLACK screen of death makes it presence known? Do this test first! It is a very easy test to do. 1. With a KNOWN GOOD pc fully booted to the WIN-desktop showing on a GOOD Monitor have a friend tap the CTRL key on the keyboard every 30 seconds or move the mouse to ensure that the pc won't go into sleep mode. 2. Power off the good monitor and disconnect it from the pc. Now reconnect the TTX9151 to the pc and wall outlet power. 3. Then and only then turn on the monitor and make note of what happens. Did you see or not see the WIN-desktop appear?
4. Now for the flashlight test. Even though the LCD panel appears BLACK, shine a bright flashlight about 1" from the screen's lower left corner and make note if you can see the Windows START icon even though the screen appears to be BLACK. 5. Turn off TTX9151 or yank the plug from wall outlet, and disconnect from pc. TEST IS DONE. Reconnect good monitor to pc to get back online. The test was to evaluate the current status of the "switch-mode-power-supply" and the CCFL inverter circuit DC source. If you could SEE something on the BLACK screen then you know that half of the SMPS is working and sourcing voltage (+5 or +3.3v) to power the vga/lcd interface board! It also means that the SMPS is not in FULL SHUTDOWN mode and only has a problem sourcing voltage(+12v to +18v) to the CCFL inverter circuit which generates 800v to 1200v ac to light-up the CCFL's that are hung across the rear of your LCD panel to produce the WHITE LIGHT needed to see what is on the screen. Now, if you didn't see the WIN-desktop, then the SMPS is probably in complete SHUTDOWN mode trying to save itself from a CATASTROPHIC, NONRECOVERABLE failure! (eg. smoke and fire) Put the TTX9151 in a safe place and get back to me with results of the TEST. lmistyrel and on aim.com or do a comment to your original post above on fixya and I'll give you advice as to what you need to do about getting it repaired or other actions/options you as a consumer/user of LCD displays have open to you. Bye for now. 12fixlouie

Dell Inspiron 1525 Laptop..the screen goes almost black after 5 minutes.


The screen goes black while in normal mode right? So try to boot in safe mode (power on then keep tapping F8 then select safe mode). Check if still happens in safe mode.

If screen does not goes black in safe mode it means there might be a software or driver causes problem when running in normal mode. You can try the following (update your anti virus software then run a full system scan, uninstall the video driver then download and install the latest one, uninstall any previous windows update or you can system restore to the time when it was working fine).

If the screen goes black even in safe mode they try connecting the laptop to an external monitor if still goes black, if yes then absolutely no issues with the LCD panel. You can try (uninstall and reinstall the video driver if still persist then this might end up replacing video card or motherboard, but before doing that update the BIOS first).

If does not goes black in ext monitor then the LCD panel might causes the problem. Reseat the LCD cable or inverter if you can.

Acer Aspire 5610. LCD very dim all of a sudden.


That sounds just like an inverter problems. There is a slim chance the bulb could be a problem, but I would replace the inverter. It is not too hard to do, no soldering involved.

You have to remove the screw covers on the frame of the LCD frame, and then carefully pop off the frame. The inverter should be on the bottom center of the screen.

Be careful, there is a high voltage in that little baby. Just get the full numbers, and do a search on the internet and buy yourself a new inverter to replace the old one.

Screen went black


When you close the lid, there is a small pin that engages the case and flips a switch to tell the laptop the case has been closed. The monitor will ALWAYS turn off then, because otherwise, the heat build up would burn the screen! Do not try to defeat this, replacing an LCD screen is usually more expensive than the value of the laptop!

Now, that all being said (and please remember), the situation you have now is (hopefully) just that the laptop tried/succeeded in going into ACPI "suspend" or "hibernate" mode.

1. Remove all cables and 10/100. Remove all USB devices. Just leave the PSU (AC power supply) connected.

2. Press the power button firmly, JUST once. Wait. And I mean WAIT, because some laptops can take 2 minutes or more to come out of suspend/hibernate, if they were very busy at the time it was shut down.

3. If the LCD screen lights up. you are done. But if it does not light up now, then proceed to step 4.

4. Press and HOLD the power button down for 10 seconds. This forces the laptop to shut down completely, even from suspend/hibernation. Some unsaved files may be lost, but tghe laptop goes cold, so you can start ACPI over again.

5. After a few minutes, press the power button again, firmly, just ONCE and for 1 second max. Laptop should start up OK.

6. Once it starts up, go to START MENU/SETTINGS/CONTROL PANEL/POWER SETTINGS and search for the "hibernation" tab. Turn hibernation OFF. your laptop obviously has some problems or lack of responsiveness with hibernation (most do). Use suspend, instead. It is much safer,. faster, and still does a good job of saving HDD and LCD wear. Please let me know how this goes for you, there are other more detailed problems that may be involved here, but I suspect this is most likely.
