Help with monitor!?!

**st_paul** · 04-08-2005, 12:11 AM

I just got my system set up but the monitor is telling me it is not receiving a signal. I checked all connections five times, I checked the screen on my home pc and it works fine. I checked the monitor with an agp video card instead of the onboard one and still nothing. Any ideas??

I'm guessing your using an lcd, if you do you have it setup properly in bios.

yes it is an lcd and i bought it from a friend that set it up and it does work fine on my pc but not with my current motherboard. i tried using my home pc monitor with the setup and still no signal. i can't get the screen to come on even with everything stripped off -> just; mobo, CPU, fans, power supply, and RAM still nothing?!?!

Ahem. What KIND of mobo do you have? The Epia's have a setting in BIOS than can sometimes default to the S-Video output and must be reset to work properly.

i'm sure you won't like that its a foxconn from newegg but it was right for the price and i didn't need a smaller one. anyways the id number is: MB FOXCONN SiS 741 K7S741MG-6L RT
how do i change the default in bios if i cannot see what i'm doing?

Unless your motherboard has LVDS and you're interfacing it via that, what does the BIOS have to do with it?
edit: ah, svideo is probably what you were thinking.

So you tried another monitor, and it doesn't work either? What can you see/hear when you turn the computer on. Do the fans spin up? Is there a beep error code? Or does it sound like it boots normally? It sounds to me like the problem is not your monitor, but with your computer booting at all. If so, chances are that your memory, MB or CPU is bad (in that order).

all the fans come on just fine, i used headphones to check for beeps and nothing. would a bad cpu cause the bios not to start up? i would think the bios might still come up without a CPU? is that right? i guess i can change out each component until i get to the mobo. i just feel like i am missing something stupid.

Since it's not a Via, it's probably not relevant but I had this issue when I first hooked up a monitor to my Via. The fans spun up, computer booted, the Windows startup sound came on but no video.

I had to hook the S-Video out to my television and when I booted, could see the video on the TV. I went into Bios and found it was set to output to NTSC S-Video. I changed it to LCD and rebooted. It came up on the LCD.

that sounds like a pita and would have drove me nuts. but the thing is my MB does not have s-video only vga.

I've had a bad CPU make the BIOS not come up. It probaly uses the CPU, if only to save some cost on the chipset. Same thing with memory - I've had a bad stick prevent it from booting at all, even when another good stick was in it.

Oh, and boot error beeps don't always use the sound out - they often only sound on the speaker headers on the MB, that drive those tinny little speakers that're only good for beeping. The headers should be on the same block as PWR, HD LED, RST etc.
