VGA signal dim

The vga signal on my screen suddenly has become very dim. All the other functions of the monitor are the proper brightness including the onscreen menu in pc mode. Can anyone help? I don't know if it is the cable or the screen or what. It has done this on a pc and a mac. Thanks, Jonathan

This seems to be a known issue with the 170MP monitors. Last time I contacted Samsung they seemed unwilling to replace this model. I took my screwdriver to it to no avail (only reseated an IC). The only solution I've found is jury-rigged at best: Enter the OSD, PC Settings. Third tab from the left is "Color Control." Selecting User Mode here, you can move all the color sliders from 50 (default) to 100. You'll get a minor (in the long run, barely noticable) rise in brightness. Whatever the root cause of this failure is, it's too deep for me to find on my own. Considering previous (read: warrantied) repair orders resulted in a new/refurbished monitor being sent to me, it's possible that we as consumers are unable to resolve this one.

No signal message on your LCD monitor screen means that your monitor is not receiving any signal from your PC graphic card. This problem "no signal" have nothing to do with the drivers installations. Have you check whether your graphic card is faulty or your cable connection properly connected/secured? ie VGA (D-sub). As far as I know there are no parallel connectors for PC Monitor connectors only, VGA(D-sub), DVI or HDMI cable interface.

Try to connect your monitor to another PC, just to test whether the LCD monitor is functional.

Hope it helps.

Moniter keeps turning off saying no video imput


Hello and Welcome to FixYa!

Check that the Input signal cable is properly inserted in the VGA socket. Secondly the Primary VGA is properly giving display signals to the Monitor/LCD. Because there are cases in which VGA is the bottle neck of the trouble you are facing.

Cross check and update me with the status,

Best of Luck,

Do RATE the solution, If found Helpful,

Hello Devsi, hi, check your VGA cable connection for loose connections, try tighten it first to see if it solves the problem. the greenish thing is cause by a missing red signal, and the distortion is caused by a missing horizontal sync signal, also check out if there are bent pins on your monitor signal cable. just unplug the VGA cable and see if the pins are in order. if bent, carefully straighten it with a slim slotted screw driver.

Black screen on acer 242lc lights come on power up


You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Check signal message when data cable unplugged. blank screen when data cable plugged


This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
