    No Green, Only Red and Blue??

    by 412know,1 must seek ·

    Ok, I’ve got this p4 mobo (PC chips)and an Intel 1.5ghz CPU. I bought the machine as is at the time. I got around to checking it out, afer discovering the FDD cable was reversed, it seemed fine. I tested all the components and ran HD and RAM checkers…no problems. I go to close the machine and stand it up, The Green goes out and I have tried several known good Video cards I have on all available slots (all 2 of them)there is no AGP slot, just a small Video jack that plugs into a rectangular pin socket on the mobo. I know I had this problem with anoher mobo, but can’t remember how I fixed it. Oh, and there is no setting in the bios to disable the on-board video, that I can see. Any suggestions? And while Im on that subject, I had a few that won’t show video at all. How would I know if it is a bad mobo or a bad cpu without being able to swap them out? I use all known tested and working Video cards both pci and agp. Thanks!

      You have tried different Video cards – have you tried a different monitor?

      412Know is right, it is most likely monitor problem.
      Check for a bent pin in the VGA plug on the lead to the monitor. But most likely it is the monitor.

        That was the ticket, bad monitor cable. It wasn’t a bent pin, but when it moved it would short out the green. I figured it out when I had just about given up on the one machine and started trouble shooting another… and then the green went out. I was like…No way. So I narrowed it down to that and viola! Thanks! You win the bing bing points..

      Yea, sounds like a monitor problem.

      Also, when you want to disable onboard video look both in BIOS for setings and on the mobo for pins.

      Be aware that some of the first mobo’s with onboard video do not have neither jumpers nor a seting in BIOS to disable the onboard video.

      Hi Y’all.. Thanks for the quick response, and my additional clues are…
      1. I did mention in the 1st post that I tried several video cards that I have that are good.
      2. I didn’t mention that I have several monitors that are all good (but I did try them, to no avail)
      UPDATE TODAY:
      I gave it another shot, turned it on, and viola, COLOR, once again I tried standing the machine upright (I usually turn them on their side’s while working on PC’s so I can see better) and the green went out, laid it back down and it went back on. I know it is a short of some type. I am going to check the pins as answer #3 suggested.

      I did buy this machine with this existing problem of the color for $70.00 USD. I figured even If I could’nt get “it” running, the parts were worth well over that, having 512megs ram (pc133), a 40 gig HD, a DVD-r and a P4 1.5ghz CPU. I almost bought a new mobo yesterday, but they don’t have anything that Sloooow brand new anymore here..
      I guess the shelf life of thewe things is about 6 months tops these days. I know it was bought in 2003. My fastest system that is working is a P3 550 mhz system, so this is a big step up, if I can get it solid. I am now an a quest for drivers, but still am having a hard time finding that maker. I thought it was a PC chips, but I couldn’t locate it at their website. A google search diredted me to Asus, but I didn’t locate it their either. The most obvious markings are PC400 ib the center of the board on a gold heat sink, chipset says XP4 HT7961. AMIBIOS setup ver. 1.21.10. Any help there or do i need to post a new question for that??
      Thanks again and keep the suggestions coming.
      Oh.. the Monitors I have are a Princeton E090, a Sony Multiscan 400ps, a Hyama Vision master 450 and a Barco Reference Calibrator(Extremly high end)I think it was $7000.00 new in 2000. They all seem to work fine.

      Opps… let me correct myself… I’m going to check the Pins as number 2 (TWO) suggested, not 3, but I will scour the bios and cmos as well to look for more options. For now Im stuck with this baby on its side because it works.. but it can’t stay this way for long. :o)

      Hi,

      Your problem could also be a faulty soldered joint on the mobo.

      If you are confident with a soldering iron, try resoldering the pins from the video connector to the mobo. Just a quick touch with a hot iron and fresh solder wire.

      Seriously, I wouldnt waste anymore time on the board, that’s the problem. You bought the pc with the backup plan to harvest it for the parts. Spend $50 bucks on a new motherboard and reuse the parts. You got a sweet deal on a good working processor, hdd, and ram. You have known good monitors and video cards. Dont destroy them plugging holes in a sinking ship. Let it sink. You can find great OEM deals online like http://www.newegg.com
      Curious, if it doesnt have an AGP port where were you sticking the video cards? UNless its pci express which I doubt based off your processor. This rectangular pin socket, it supports your other video cards? If there is no Bios turn off attribute for the onboard video or AGP port then its an unscallable pc. Well this is my .02 in the matter it sounds like the onboard video jack is damaged, save your time and get a great deal either online or at a computer show and you will have more options to make the pc last longer on a minimal investment.

        This was the strangest MOBO I have seen for a relatively new one. It only has 2 pci slots. No AGP and little 1/2 socket for a specialized modem. Very inflexible. I finally tracked it down to a PC chips manufacturer. I had to actually remove the board and on the bottom, there was a small ID number.. I wrote them telling them If I had put out such a board, maybe I would have hid my name as well.. 🙂

      This is the reason OnBoard video should be outlawed!.. anyway…

      OnBoard video has 3 methods of being turned off. Inserting a REAL video card, jumpers, or BIOS. There is a fourth way, but I’ve never been able to get a sledgehammer to only crush the vid chip.

      I’m inclined to agree with the electrical short theory. I’d say check the connectors on the vga connector, but if you’re getting the same problem with a normal vid-card, you’re not using the onboard connector anyway.

      Check to make sure all chips are seated is kinda dumb, but can never hurt. (Unless you leave the power on and do it after washing, but not drying, your hands)

      Pull the MB out, and put it back in making sure all the posts are secure and the MB has no bend or bow in it.

      Have you thought of maybe just running it lying on its side? 😀

      To find out the maker of the M’Board you need the BIOS String on the bottom of the monitor during the POST. You need to copy this down completely and usually press the pause button on the keyboard so you can get it correctly. As you already know the maker of the BIOS you can look on their Web Site for a maker by the explanation of the BIOS String or try

      http://www.biosman.com/

      and follow the links to the BIOS Maker and then the listings for the M’Board Maker as described by the BIOS String.

      Firstly to see if you do have a problem with the M’Board or just the way it has been mounted I would remove it from the case and plug in a PS and just add a click switch to the Power On pins to start it laying on its side on an anti static surface. Once you have it running you can then tip it onto its side to see if the problem persists but I’m betting that you’ll find it was badly fitted to the case or some crud has shorted out the back of the M’Board and is causing the problems. O good clean out will never hurt but remember if you use compressed air to hold the fans still to prevent them from destroying the M’Board as they spin and generate power.

      Lets know how you get on.

      This sounds all too familiar. I have removed all boards cables and chips and then after removing the mother board there it was a jammed-up screw stuck btwn post and board that the original builder of the system left there or rolled from some place else. You get the hint. Good luck!!

      Greetings all… THANKS for the info. I know it has been a while since I’ve asked this and I did reslove it last week or so.. The trouble then was I could not get into my lycos email account for whatever reason. Kept saying session expired.. so anyway, I was not able to access this account or see that I had more answers waiting and I both appoligize and thank you for the responses. It looks like answer #2 was the winner with a bad monitor CABLE with a shorting pin (It was intermitant, thats why worked on its side.. didn’t upright)Thank god the monitor a removable cable, sure would be a waste to have to toss a monitor just for the cable. I have a pretty hefty selection of 19in monitors that are all killer. Strange enough, I didn’t buy 1 of them. Everyone that has bought a LCD out here just tosses the old one out in the street. I have found about 15 working systems in the last 6 months and several more that were just parts. Anyway…once again.. thanks! Oh… and that machine ROCK’S now!. It’s pretty fast.. at least by my standards.
