Paviollion HP HPE 112Y - no video SIgnal from the computer - monitor works

I have a desktop HP Pavilion HPE 112Y.  About two weeks, the video has stopped working.  I replaced the HDMI cable, we replaced a VGA cable, etc with no luck.  I plugged in the screen of my laptop and it works fine, then it is certainly the office.  All I get is a message "No. Sigmal video»

I tried to connect the monitor directly on the edge of VGA video connection - without going through the video card.  No luck.

.  I can not get the system starts from the CMOS or restore screen.  Hard drive runs, but goes into the cycle of continuous type "whiring.

System is about 2 years old, running Windows 7 64 bit.

Help!

Hello

Try this procedrue:

Disconnect the PC and open it. Clean all the dust. Carefully, remove and replace all the cables towards the mother board one at a time. Do the same for memory DIMM and the video and the sound of cards if you have a.  You can buy a can of compressed air to blow the dust out of the heatsink from the CPU.  Plug your PC back in and give it a go.

If the above does not help this procedure: power.  Do not skip steps.

Finally, try to clear the CMOS memory.

    * Press the Menu button of the monitor to open the OSD (On Screen Display). The bottom of the screen should display a resolution. This resolution should match the resolution of the default monitor. The two monitors: 1920 x 1080, 60 Hz

    * Brief description of the problem monitor? Monitors have been implemented following the instructions on page 25 of the Dell online manual to connect the monitor to function DP multi-flow (MST). DisplayPort cable is connected to V3900 output MiniDisplay port DisplayPort graphics card in the 1st U2414H; second DisplayPort cable is connected to the DisplayPort on 1 U2414H monitor output and MiniDisplayPort in the 2nd monitor U2414H. Dell U2414H drivers have been installed from the CD provided and both recognized by Windows. V3900 graphics card Driver is up to date with the EyeInfinity software. Source of input on both monitors the Mini Display Port value. Display settings on both monitors Display Port 1.2 value activate. Resolution of the screen on Windows 7 shows: (a) two separate Dell U2414H (mini Display Port) screens, with each resolution 1920 x 1080, multi (b) displays the value "to extend these displays. The two views work with Setup leading up to and acknowledged by the graphics card.

    Problem 1 - all the time - monitor power buttons are lit, the computer is turned on, then monitors lights don't - they show 'Power save mode' and then turns off. To hit the power button on the computer to shut down Windows. Only way to get these on monitors is unplug cords from the back of each monitor, wait a few minutes, plug in the power cord, start computer and then both monitors will start up and sign of windows to the screen will appear and monitors will work. Normal operations for a full day of work if you do not restart. If you need to restart during the day (like when you get a software update), the same thing happens. Start the computer to restart, but the monitors come back on not and remain dark. There is nothing wrong with the graphics card V3900. He is certified by AMD and DisplayPort.org to work in an environment of STD DisplayPort 1.2. I had previously two 215tws Samsung SyncMasters connected to each output V3900 Grahics card and they work very well in extended mode for years until a SyncMaster 215tw started shaking like crazy. A SyncMaster has been connected to the out display with a dongle and a DVI cable Port. The other SyncMaster was connected to the DVI output on the graphics card. So I decided to buy these two U2414Hs. Technical support Dell after many phone calls and e-mails finally advised me that there is a problem of "compatibility" between my computer and the U2414Hs and recommended that I return the monitors. On the web site of the U2414H AMD has not been certified by AMD to work in a DisplayPort 1.2 STD Set Up. Other former Dell monitors are certified by AMD to work in the Display Port 1.2 Setup. DisplayPort.org lists the U2414H to work with Display Port (it does not say that it will work in a DisplayPort 1.2 Set Up).

    Problem 2 - shift perceptible in the entrance of Microsoft Blue Tooth keyboard and mouse and PS2 Keyboard and mouse. All the drivers are up to date. When you type a phrase, it takes a few moments for the text displayed on the screen using a keyboard. Both the mouse connected and the Bluetooth mouse are unresponsive sporadically for a few moments until they finally react. It happens regularly during the day. The monitors provide excellent clarity when you work. The stand is ideal for office property. Before these monitors are returned if no one knows what causes these two problems and does anyone have a solution? Should I stop using the Display Port 1.2 and hang them using HDMI with active dongles? If I have to return these two U2414Hs, I considered the 2 two U2413s. Someone at - it all opinions on the last U2413s from Dell? I have read some real problems with ghosting that I just haven't the time for more. The remanence correction in the models of U2413 sold in 2014? There are very few monitors on the market with Display Port in and out to the back to support DisplayPort 1.2 STD Transport.

    Thanks for any input.

    I had to remove my VGA HDMI DV card and now the DP (display port) works very well. Don't need to use a HDMI cable. Display Port 1.1 is reported as the problem in order to remove the card solves this problem.

  • No video signal from HP Pavilion monitor m7560n

    HP Pavilion m7560n, THE graphic card NVIDIA GeForce, monitor HP 2159 m, Windows XP.

    Screen went black with the message "no signal". I tried the monitor and cable on another computer, it worked, this isn't a problem with the monitor or the cable. The VGA connector and graphics is integrated in the motherboard, so I can't try another video card. TV-out connectors, isn't the PC so I can't use TV as a monitor. Is there another option, how to continue with the debugging before replacing the motherboard?

    Thank you.

    Most of these cards in PCIe x 16 v2.0 should work on your computer as long as it requires a 300 watt power supply system power or less. The 2 x 0 series is the oldest, while the 6 x 0 series is the most recent. Cards are plug-and-play... but you need to install a device driver for the card. The HP BIOS should automatically detect the card and disable the integrated graphics card. If you still have problems after the installation of a card, we will have to look for other issues.

  • Computer off, showing U2913WM "there is no signal from your computer press any key on the keyboard.

    Hi all

    Any help on this incredibly annoying would be much appreciated; I googled the out of him, but without success. I have a month or so old Dell U2913WM which I am more than happy with picturewise, but he demonstrated a very annoying problem. Whenever my PC goes to sleep, or worse, when I turn off my system, the monitor goes power save mode BUT after 30 minutes or so flashes upward:
    "There is no signal from your computer. Press any key on the keyboard or move the mouse to wake him up. If there is no display, place the monitor button now to select the correct input in the on-screen Display menu source. »
    It then repeats this message every 3 minutes approximately.

    I tried to reset the options in the menu of the screen, change the PC drivers (although this may not be the issue once the PC is turned off) and checking the dual link cable DVI for bent pins. Nothing worked and he drives me crazy! I have also another 22 "Dell Ultrasharp plugged on the GTX 780 and who falls asleep without problem. Any help would be most welcome!

    Thanks :)

    OK I fixed this annoying problem. I thought I'd post here in case someone else falls on this problem.

    To remedy this I simply connected via DisplyPort and the monitor is no longer wakes himself of no apparent reason.

  • I have can´t scan in Officejet 6700. Printing from the computer works perfectly.

    I have a new 6700 Officejet connected with the USB cable to the computer. (Windows XP) Printing from the computer works perfectly. Sannen works onl + y from time to time. When the attempt at analysis, he says that there is no connection between the scanner and the computer. I changed the USB cable to exclude damage to the cables. I tried all the help files for HP without result. Who please can tell me what is happening

    I think I know where banhien is trying to guide you. I'll explain his instructions in more detail below.

    1. make sure you are on the desktop view.
    2. double-click on the icon on your desktop that resembles your printer.
    3. under the section titled scan, you should see "Manage Scan to Computer".
    4. click on "Manage the Scan to Computer" and a window that's going to Enable.
    5. click on activate to activate computer scanning.

    If the icon is not on the desktop, or does not work, you may uninstall and reinstall the printer. If you need to do this, be sure to use the latest version of the software following the link. Hope this helps to clear things up a bit.

  • HP Officejet 8610: Unable to fax from the computer

    I have a HP Multifunction printer and use the fax from the computer option several times a month. I discovered this week that she did not work AGAIN. I have had this printer about a year and need to reinstall the software several times. When I select the fax printer and say 'print', the fax screen should display and ask where to send them, but nothing happens. When I check the devices screen and printers, it shows the fax as unrelated to printing or pending tasks. The machine is connected because I can print to this well, that's just something wrong with the communication by fax. I found that uninstalling and then reinstalling the printer solves the problem, but the number of times that I needed to do this is frustrating. I guess that something is messed up when windows does its updates. Is there a setting of simple connection that I could update instead of reinstalling everything on all of the computers on my network? Maybe HP could be added a correction for this option to their troubleshooting.

    Hello

    You can use the universal Fax HP driver instead:

    1. Download and extract the following:
      http://FTP.HP.com/pub/softlib/software13/COL60874/DS-146586-1/HPUFDDriver.zip
      (Use a program like Winzip or right-click on the file and select extract all).
    2. Open the extracted folder and run setup.exe
    3. Follow the instructions on the screen, a printer HP Universal Fax Driver will be created on your PC.
    4. HP Universal print driver Fax, select your printer and check the box to add a queue for your printer.
