Montor will cme on then cut off. A VGA cable sign will come on before it cuts off

Try booting in VGA mode to disable the Nvidia drivers, see if this works ( also try safe mode)
Try connecting to an external monitor, see if lines vanish

If the problem goes away in vga mode, Nvidia drivers are the problem
If the problem remains on the external montor, the issue is with the graphics chip
If it vanishes using an external, issue is with the screen being damaged or vga cable damaged

the Envision H170L Monitor uses an interface 1.0x VGA - 15 pin HD D-Sub (HD-15). The same VGA cable wildly use in different computer brands..I was wondering why you have not found a replace for that cable. It can be purchase from any computer store.

If you are planning on cutting the wires and solder it together that would be easy if you have the diagrams of the pin numbering for male VGA connector and the female VGA connector. Check first this diagrams and follow strictly the coding of the wire so that it would be successful when connecting it together.

It is also better if after you solder the wire, you will use an shrinkable tube on the connection. Cover the whole sections of interconnected wires with shrinkable tube before you use the vga cable.

this should be enough to ensure signal is going out of your monitor port on the back of your Dell.

the projectory also supports montor to montor cable rather than vga

suspected for VGA the projector needs to be set to video input
and for monitor to monitor cable to computer input setting.
if picture is not seen straight away cycle FN combination until picuture is seen.

cut power to unit pick up water pump unil u see bottom of pump..try to spin manuely..chances are your pump is locked ..if spins freely ohm out motor windings..make sure ur getting power to pump

did you try to check the VGA connector maybe cause a damage or not properly connected due encounter block screen or no signal or question mark sign like this (?) color yellow
or use other VGA connector try to do it

i have a 26" insignia lcd tv that i use as a montor uou musr set the screen resolution on your computer to 1024x768. if you use a higher resolution it will say no signal.so use your montor to set the resolution to 1024x768 then hook it to the vga and it should work. bob griggs

Here you go:

I got hold of an old vga cable (15 pin), cut off the male end. I then cut the existing cable comming out of the monitor. After soldering the wires together and lots of electrical tape wala - it works.

Now the problems I incured - Don't solder wires together based on color, they probably will not match. Peel back the ends of the cut off connectors and find each pin with a Multimeter. Once you find each wires match solder them carefully and tape. When done test and if good place a short splint on the spliced area and tape. This will keep the wires from breaking from movement. Good luck.

Posted on your previous question. Check it if it can help you already.

leave comment if that thus not help.

Hi, I have AL1716 so pretty the same - both cables (power and analog VGA cable) are inserted into sockets, probably your VGA cable can be screwed in - just unscrew it and go to nearest PC shop to buy new one. What a good cops you have !!
