Question about Dell Inspiron 546 MT Desktop Computer

1 Answer

546 will turn on normally(light is blue) but won't display my monitor and usb ports power some items and not others.

546 fell over yesterday while running. Not far just on its side. When it did my monitor when black and gave me a no signal display. I turned it off and then powered it back on with the panel off. Fans work fine, nothing looks broken or loose on the motherboard. DVD/CD rom will open but not stay open. Small yellow light is on in the bottom right hand corner of the motherboard(not sure if this is normal). Will power my usb wireless adapter but not my moose, keyboard. They work fine in other computers. any ideas?

You probably dislodged some components in your computer after it fell. Suggest that you open the computer and re-insert the memory modules and other cards inserted in the motherboard. Unplug it first and on a non static surface like a kitchen table.

SOURCE: dell 4600 no monitor signal

Hey Tony,
If you haven't already: pull all pci cards:
If you pull the ram, and you get no beeps at post, it's likely the main board. Does the pc beep at all? with or without ram? If not, likely the main board. Sorry. Hope this helps...

Samsung syncmaster 2220 blinking blue light and no image display


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

Connect dual monitors


The port with 15 holes is a VGA connector and most monitors have a connection for those it's a blue connector. The other you describe sounds like a DVI connector. Most new monitors have that as well and it's a white connector.

11750867-tewsfb12kpevcqwroz5uwqx5-2-0.jpg Once you have both monitors hooked up and turned on, they should automatically come on and show your Windows desktop. You may have to tweak the resolutions if the monitors are different. That can be done in the resolutions settings : Control Panel\Display\Screen Resolution

This video, starting around the 2 minute mark, gives a good overview of those settings and what they do.
How to Windows 7 Multiple Monitor Setup

One thing he mentions that is important is that the monitors are set to the right inputs or source. Look for a button, usually on the right or bottom of the monitor, that says "source" or "input" or has a symbol of an arrow pointing at into a screen - it looks like #2 in this photo:

http://en.community.dell.com/resized-image/__size/550x0/__key/communityserver-discussions-components-files/3529/6354.monitor-settings.JPG

The monitor connected with the blue VGA connector usually says "VGA" or "Analog". The monitor with the white DVI connector usually says "DVI" or "Digital".

Good luck!

Systemax Ascent HA3200 RTS won't boot - fans come on - no display


The motherboard seems OK as it is displaying signs of life. The Monitor should display something before booting up, which it is not.Please do the following. 1. Remove the RAM and reinsert the DIMMs into their sockets and boot up. 2. Disconnect the HDD data cable from the HDD and the motherboard and reconnect. Boot up. 3. Disconnect the monitor and reconnect. Boot up. At boot up press F2 and set the PC to default settings. Boot up. Later when you want to apply your settings, keep noting down what you did when. Just in case.

DO YOU FIX PS3s... I have tryed everything i can think of incloding different cables HD & normal,different TVs HD & normal Also holding down the power button and waiting for the beeps.But nothing...


  1. Make sure the HDMI cable is connected to the HDMI OUT port on the back of the PLAYSTATION 3 system. Connect the other end of the HDMI cable into the HDMI Input port of the TV or display monitor.
  2. While the PLAYSTATION 3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive power button on the front of the system until the system goes into standby mode again . (So the light cycle would go from: red light --> green light --> then back to red light). This will ensure that you have held down the power button long enough to reset the Video Output Settings.
  3. Turn on the PLAYSTATION 3 system and once the system finishes powering up, the Video Output Settings will automatically reset to the standard resolution (or detect the current display output settings of your TV/monitor).

SAFE MODE

Monitor : no display and blue led light is blinking


The power supply is the first thing that the 110v electric line goes into. The invertor is the next item past the power supply, or sometimes contained within it. I do not thing monitors are a DIY repair.      First substitute a different monitor to confirm that it is, in deed , the monitor and not the video card.

Connecting 2 monitor and tv


Multiple monitors overview On many portable computers and some desktop computers (those with two video ports on one video card), you can expand your display to a second monitor by using Dualview. Dualview is very similar to the multiple monitor feature, with the exception that you cannot select the primary display. On a portable computer, the primary monitor is always the LCD display screen. On a desktop computer, it is the monitor attached to the first video out port.
Once you attach the second monitor and turn on your computer, use Display in Control Panel to configure your settings, just as you do with multiple monitors. Dualview can be used with docked or undocked portable computers.

Arrange multiple monitors To arrange multiple monitors
This procedure applies when two or more monitors are connected to one computer.
  1. Open shortcutcold.gifDisplay in Control Panel.
  2. On the Settings tab, click Identify to display a large number on each of your monitors, showing which monitor corresponds with each icon.
  3. Click the monitor icons and drag them to positions that represent how you want to move items from one monitor to another, and then click OK or Apply to view changes.
note.gif Notes
  • To open Display, click Start, click Control Panel, and then double-click Display.
  • The icon positions determine how you move items from one monitor to another. For example, if you are using two monitors and you want to move items from one monitor to the other by dragging left and right, place the icons side by side. To move items between monitors by dragging up and down, place the icons one above the other. The icon positions do not have to correspond to the physical positions of the monitors. You can place the icons one above the other even though your monitors are side by side.
