Just bought HDMI to DVI cable to connect my VL193 to my HP laptop - unable to get the monitor to "pick up" the signal - just a blank screen - if I power it on & off, just goes right to power...


Hi

Desktop PCs automatically seek an external monitor to output graphics to. Laptops default settings send the image to the internal monitor. You need to manually instruct the laptop to export the image to an external monitor.

With the cable connected and the monitor powered up, try pressing the Fn key (bottom left of keyboard) on the laptop and simultaneously pressing the function key at the top ofthe keyboard with an image of 2 monitors (often F5 or F6) to sent d the image to the external screen.

I hope this helps.

My Samsung SyncMaster 740N occasionally turns itself off. Timing varies and the condition varies. Usually the screen just goes black - from seconds to hours after it is turned on - the blue LED remains...


This could be because of the 'eco' friendliness of the monitor. Basically a lot of monitors are designed to turn off into a low power state when not in use so to preserve power and life of the monitor. I would return the monitor as the sensors that control this seem to be broken in your monitor.

How do I turn it on


Hello.

To power on the Gateway VX750, press the power button on the front. The power button has 3 sides with a "G" in the middle.

The LED indicates the power status of the monitor.
  • Not lit - The monitor is turned off or does not have power connected.
  • Blinks one time and then goes off - The LED blinks one time when the monitor's power cord is plugged into an AC outlet to indicate that power is detected.
  • Lit solid blue - The monitor is turned on and active.
  • Blinking blue - The monitor is in power saving mode. Before entering power saving mode, a message briefly appears.
Hope this helps.

Sound fluxuates,crackling sound samsungTX-R3079WH sound goes up and down automaticly


If the sound FLUCTUATES up & down, try turning off the AutoVolume in the sound menu. You didn't say if it's one or all speakers crackling. Crackling is either a speaker or circuitry issue. Adjust the balance away from the speaker that crackles, if it stops, that speaker is probably "fried". If it still crackles, I'd turn off the speakers and run the sound thru a stereo for the quick, cheap fix. My Samsung (10+ years old to be fair) crackles due to a circuit issue but if I SMACK the left side speaker (behind which is the sound board and side panel connectors) it stops for a while. Maddening. I think I broke it squeezing it into the furniture it's in, pressing on the protruding RCA plugs. Dumb design.

Screen going black, green LED staying on


Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.
Your problem is the power supply or the inverter on your board, you can replace it and it will be fixed.
Easy Fix REALLY EASY FIX
(inverter is what supplies power to your backlights. A lot of the times the reason a monitor goes black and the green power button is on, is because the backlights shut off. in most designs of the 1730 the inverter is embedded on the power supply. That is most often the case on this problem. Power supply/Inverter=Replace it and you will have a spanking new looking nice monitor working again. :)

Monitor Continually Goes Blank


You are right in assuming it to be the monitor.
It is the inverter circuit that powers the backlights inside the LCD.
No backllight, no view. If you shine a bright light into the screen you will see it is still working, just not visible.

The Viewsonic range of monitors have a habit after several years use developing bad capacitors that need to be replaced. It's something that happens to most LCD's and alot of other electronics.. so not a design flaw, just age.

If you have modest electrical knowledge then its an easy job, If not then take it to your local TV repairman and have them do it. It should not cost alot to have it done. The main expense in this case is the labour.
Call a few shops in the area and get rough quotes to have it done. You will be surprised how much the cost can vary for the same simple job.
