How do I connect a Sylvania monitor 6842PFM to a Dell computer?

When the power light is flashing the monitor is not getting a stable signal. This is hard to answer without direct troubleshooting. Check the cables first, make sure they are connected securely. If you still have problems test another monitor you know works or move monitor to a computer you know works, this will determine if the monitor is the problem or not and tell you if it is your "graphics port or adapter". If another monitor works fine, use the working cables to test the "broken" monitor. If you have an "all-in-one" computer, ignore the above steps and use a start-up repair disk. The reason this is hard to troubleshoot is there are so many things to diagnose. More than likely your "graphics card" is failing. These are some tricks to repair. You can update the driver, buy a graphic card separate from the stock port.

Hi
you have to be sure if the laptop is running the alert LEDs, the sound of the fan in fucionamento, use an external monitor to be certain. and finally replace the LCD and its. cable

It sounds like you have been pretty thorough trying to resolve the lcd problem

A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode, if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness. Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over. Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop. Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector. Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken. If the monitor doesn't work, the motherboard or video card might need to be replaced. Hope this helps

I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

Do a hard reset by turning off the computer and removing the battery and unplug the AC adapter. Without any power source, press and hold the power button and put everything back after. Power on the computer again, if it does not work, try to connect your laptop to an external monitor. If it shows some display it means that the LCD monitor of your laptop has gone faulty.

The AC adapter for this monitor is REGULATED 12VDC 4~5Amp. Is the one you are using regulated 12VDC with at least 4Amps?

But you also may have problem with the monitor itself, cannot tell until you use the correct AC adapter first.

Is the PC monitor connection - a DVI or DVI-I connection a 15-pin VGA connection an RCA video connection?
Have you set the television input to match the connector used on the TV?
The display resolution on your computer may not be set to a resolution your TV can handle. There is no point trying to put a 1280 by 800 signal into a VGA connector. Start with 640 by 480. However, this will not give you the high resolution you have come to expect from your PC's monitor.
This set also has HDMI input. If your computer has a DVI or DVI-I output, you can buy an adapter that will connect to that HDMI input. Note that this will only handle the video portion of the output from your computer and you will have to use analog connections for the sound and figure out which TV menu input selections allow high definition video with analog sound (not all sets can do this).
Note that LED TVs are not like CRT TVs where an electron beam can put a dot anywhere on the screen. An LED TV has fixed resolution modes.
It might be necessary to use a software product like "PowerStrip" to create a custom resolution mode that will show a high resolution image that will fill the screen of your TV. I wound up using 1352 x 648 to give a full screen image on my LED TV using the HDMI input. ("Your mileage may vary.")
There is a lot more to connecting a high resolution computer display to an LED TV than just plugging it into the "PC Input".

The board with 200-100-SH700 on it may be the problem. I came up empty trying to find anything with that number, there should be some other number either ink-stamped on the board or on a paper sticker.
Google can be your friend if you find the right number.
Somewhere there may be someone with one of the same with a broken screen. Ebay?

I suggest you to perform these steps.
Test the AC adapter Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board.

1. Remove the battery and disconnect all external devices from the computer.
2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
4. Press the Power button to start the notebook PC.

If the notebook does not start or the display is blank then check the power indicator light or power socket LED. I suggest you to connect the notebook to external monitor and check whether its working or not. Then please perform the harddrive self test also.

Hi,


Do you hear a beeping sound when turning it on? Try connecting an external monitor (Desktop monitor) then press FN+F8 (Dell laptop only) and FN+F4 (HP laptop only). If it works on an external monitor, you may need to contact your computer manufacturer. check the warranty and request for an LCD monitor replacement.

If you hear a beeping sound when turning on your laptop or no power (no light). you may need to reseat the memory (RAM) or check the AC adapter (power adapter).

Let me also know the system model and computer manufacturer.

Keep me posted.

Thanks.
