Question about Sceptre X7GNAGAV 17" LCD Monitor

1 Answer

Was intermittnet at first, now nothing. Power light just blinks green while you have the VGA cable plugged in and you can't turn it off with the VGA cable connected to an operating computer. Unplug the VGA cable and the power light blinks green and amber and you can turned it on and off. I tried a different VGA cable - no help. Have not opened it up and looked at anything yet. The last thing I saw on the screen was a message saying "No video signal".

Look for bad caps, if you see any bad one you should replace them in a set.
Bad cap can look normal.

I've got a Scanport H21 monitor that the green light comes on but has a black screen. Can not dring up a menu or "VGA IN" message.


You can try a different cable for VGA. Check if the port is lose. The green light is only indicating a proper power supply to the monitor. The display is very much dependent on the VGA cable. If your monitor also has HDMI port, you can try to connect using that cable (provided the display adaptor also has HDMI port). If nothing works for you, take it to a hardware engineer or local repair shop.

Red light on computer monitor, black screen, but nothing else


if the power indicator light from green then turn to red with no display, check the power supply board which may have leak or bulged capacitors. check also weather your vga cable is good, if no signal the monitor will turn to off.

My HP Monitor Model No: L1706 problem


I sure sounds like you have backlight problem, since when the VGA cable is connected the power LED turns GREEN and blinks when VGA cable is disconnected, it means the video signal is getting to the monitor OK, so more likely the problem will be in the monitor, but just to be sure, you should also try this monitor with another PC first.
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed HP and other monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

I can't get my tv to turn on... nothing but blinking red light


Dont know if this will work for you or not, but my brother gave me his because of the same problem. It would power up and a green light would come on, then after 10 -15 seconds it would change to a red blinking light. I plugged a usb cable into the service port on the side and left the other end unplugged. Then plugged the tv back into the power. i took a small screwdriver and ran across the contacts in the end of the usb cable until both the red light and the green lights came on. I did this several times listening fot the clicking noises in the TV. after doing this for approx 20 seconds, i pressed the power button and the TV worked fine. 5 days now and no problems. Only thing I can think is I somehow reset the software and now it is working fine. Hope some of you can figure this out and give it a try. if the TV is just sitting, you have nothing to lose

NEC MultiSync FE2111SB 22in monitor problem


a blinking green light usually indicates no video signal. check your cables, and if you have another computer, try it on that. otherwise, carefully check your vga signal cable, and the connections on the neck board [where the crt plugs into]

SBlinking green light


Have you tried disconnecting the power from the wall? Or power cycling your entire entertainment center? Possibly even check to make sure the VGA cable (or any other cable) didn't somehow come looose?
