Your comment that you have no sound and the monitor is showing no VGA connection, then you have a gross leakage in your PS. I suggest that you copy the voltages and colors that are on the PS and then measure each voltage (remember that red=5V and yellow=12V and so on. I am fairly sure that you have a PS problem or an overload causing it to shut down. Thank you very much. CONSTANTIN (arzconst)

My computer is a SyncMasterP2570HD i cant get any sound to come out but it is detecting sound how do i fix it


The Samsung SyncMaster P2570hd is a monitor with speakers; it isn't the computer itself. I'll assume that you are dealing with a computer connected to the monitor and not a set-top box. Make sure that Mute is not enabled on the computer. There should be an icon on the lower right hand side of a Windows desktop. If the mute is enabled, it will have a red circle with a diagonal line through it. Left click on the icon to remove the mute (change the volume or click on the mute icon). Test the monitor's speakers by connecting it to another device with known good audio output.

Next how are you connecting the monitor to the computer (VGA, DVI or HDMI)? If you are using VGA or DVI (including DVI to HDMI), you need to connect an audio patch cable (3.5 mm) between the speaker (green port on the back of a sound card) or headphone jack of the computer and the audio input jack of the monitor. The audio input jack is between the DVI and VGA ports. You can test the output of the speaker jack on the computer with regular computer speakers. Plug in the power cord (or USB cable) for powered speakers. If the free-standing speakers work, check the volume setting on the monitor with the +/- buttons to the right of the menu button. Do not press menu first, though. If that doesn't solve the problem, continue using the separate speakers. (Unless the monitor is still under warranty, it usually isn't worth taking apart a monitor to replace the speakers. You may be able find replacement parts online.)

If you are using an HDMI cable, check the output audio setting to see if the HDMI audio is available. For Windows, click on Start > Control Panel > Hardware and Sound (Windows 7). Then click on Manage Audio Devices under Sound. In the Playback tab, check what available audio devices you have. Make the HDMI the default device by right-clicking on it and selecting Make this the default device. (Other versions of Windows will a slightly different route to this panel.) You may need to restart the computer to get the audio signal on the HDMI cable after setting this. Note: not all video cards/computers support HDMI audio. If you don't see HDMI listed in the Playback devices, connect an audio patch cable as with a VGA or DVI cable, described above. Use stand-alone speakers if the monitor's speakers are bad.

I hope this helps.

(I have had the speakers fail in monitors; <$30 separate speakers are an adequate replacement for those built into a flat panel monitor.)

As soon a the Monitor turns on...the green light turns to orange (this usually comes on when the computer is idle) with the same black screen.


Please check by removing the VGA Cable from the Cabinet and check the whether are you getting VGA connection message on the monitor screen or not ?
If you are getting the message on the Monitor screen after removing the cable then check the Mother-Board
or else get monitor repaired

P4vm800 not working how to solve this probelom


Good day sir, hi, lets make sure first that your motherboard is good, so we need to test it, just prepare the folowing items.
  1. A good working power supply, to test: place a jumper wire across the green wire and any black(or sometimes the red with work) wire on the 20/24 pin power connector. Plug it and see if the exhaust fan run.
  2. A good set of Ram, just make sure its good. if not or in doubt buy new one (only one module) if you want. (you can keep the doubtful ones and test it later)
  3. A keyboard.
  4. If your motherboard has no VGA onboard, A good VGA card.
  5. A thumb speaker, or you can use your PC case speaker.
Okay lets assemble, on a table:
  1. Place your motherboard, (make sure no metals underneath) connect the Power Supply 20(or 24) pin to your motherboard and the 4 pin 12v connector. (if your motherboard has one).
  2. Connect the pc thumb speaker or your case speaker.
  3. connect the keyboard.
  4. connect the RAM, make sure it clicks as you install it.
  5. Optional VGA card. Onboard vga will do. Connect a monitor. plug in the monitor.
Okay, plug in your power supply, (exhaust fan is off at the moment) locate the power button pins, short them with a screwdriver. (fan is now on)

Now check your Keyboard. you will see two sets of lights, first set is Num Lock + Scroll Lock + Caps Lock, then a few seconds the second set: Num Lock only. at this point your motherboard is good.

Also check out the PC speaker beeps.
  • 1 beep mean good.
  • 1 long and 3 short beeps VGA is bad. (it may help if the VGA is snug and fit on the slot). If on board VGA, use a new AGP/PCIe card.
  • Continous long beeps. cannot detect memory
  • Continous short beeps, motherboard. (or memory sometimes).
  • No beep, fan is on.at this point do everything again. (do it several times until the board responds)
Hope this helps you. feel free to ask again.

My monitor says there is no signal from my new Dell Studio


Try reseating the video card in your new computer. Sounds like it may not be seating in the slot properly. Take it out and put it back in with the power off and then hook everything back up and then see if you get video,.

PF790 monitor picture issue


Was it dropped? If so, it could be a board crack or damage to the CRT. Was it stored in an unheated garage, shed, or attic, etc.? Damp air or widely changing temperatures can cause condensation on the circuit boards. Minerals and other impurities can collect on the board via the condensation, leading to some nasty corrosion. Plus in my opinion, late-model CRT monitors are a real pain to work on. Many of them have so many shields and so many screws that before you get the board free to work on it, you're sick of messing with it! *grin* Then when you do some work on it and want to test it, you have to do a lot of reassembly first. I'm sure others will be tempted to jump in here and tell me how crazy I am, but unless they belong to a family member, I don't even work on them any more. When it comes to monitors, I only work on the flat-panel types. But if you go for it, look for electrolytic capacitors with bulging tops or leaking bottoms, bad board connections, etc. Good luck!
