Dell 1720 laptop screen "blooming". looks like too much voltage to screen. 2nd output to TV is fine. Pre windows screen shows vertical lines across entire screen. occurs during POST so is not windows/driver related. inverter or screen issue? Thanks.
If you can see the vertical lines during POST, try to check the vertical lines in BIOS. If the vertical lines are there in BIOS, the only thing you can do is to replace your LCD screen.

Hello Townsend,
It sounds like a problem called blooming, or you are having a problem with focus control which are signs of a problem in the horizontal and high voltage section of the tv in the case of plasma TV this would be the excitation circuit. I would suggest that you take the set to a TV repair shop to effect repairs.
If you are running Windows 7, if you type in the wrong password once, it normally says reset password... below the box for the password. Insert a removable disk (such as USB, floppy disk, etc.) and follow the prompts.
Remove main battery and try again, next! sub out the ram memory one at a time and test, have the power supply adapter checked for voltage output, if okay! the DC jack in the laptop is a common source of trouble, "from intermittent operation to no power" at this point the laptop must be dismantled to investigate further.
That's an interesting problem. It sounds like it's applying new display settings, but I'm not sure why it would do so over and over again. I would suggest trying to start Windows in "Safe Mode". To do that, as the computer is booting, hold down the F8 key to get the "Advanced Boot Options" menu. Maybe this will get you to a normal login screen. If so, you should try to change your display settings to the simplest possible and then reboot. I hope this helps.
That, & most, earphone sockets, simply doesn't have enough "Current" or signal voltage to drive your TV set's audio in Amplifier. You need to get a Pre-Amp, to amplify the signal, up to a level that can be used by the TV. So you need to purchase, or build from a kit, a small stereo pre-amp and insert it between your laptop & TV audio In.
It can be the AC power jack on your laptop. Believe me I have an inspiron myself and this problem is a real pain. However you can easily fix it by un-soldering the old jack, re-soldering the new one in. You can find a replacement on e-bay. If you are not good at soldering,I suggest you take professional assistance. Its a very inexpensive repair.
I would need to know what operating system you are running because Vista has a setting for the display brightness when running on batteries. I would suspect that, that setting is turned down to conserve battery power. If this is not the case, then the battery may be too weak to put out the correct voltage requirements for the display. If you have Vista, go to the control panel > power options > In the left pane, look for the display brightness > here you can change the brightness for running on battery and for AC power.
you just need to enable the 2nd monitor in display properties, right click on desktop and select properties then settings and right click on the 2nd display select attach.
or look at the keyboard press FN and look at the F1/f12 keys, one of them will turn the external display on or swap between outputs.
