  • VIA EN15000 - losing VGA output signal?

    I have motherboard VIA EN15000 with M2-ATX supply for few months now and I have experienced this problem only in the last 14 days. The configuration is the same from the beginning.

    I hibernate Windows everytime when I leave the car. M2-ATX jumpers are 5/45 (5 seconds to begin hibernating, 45 seconds to cut the power). Later I want to turn on the computer, but I see a message NO SIGNAL on LCD - Windows normally resumes and music is playing, but VGA output is disabled?

    Only manually reseting the bios (via jumper) help to solve the problem.

    Anyone with same same problems?

    Regards!

    I forgot to mention, LCD is powered by 4-pin P4-ATX connector on M2-ATX power supply.

        What you mean by "cuprit"? If I reset bios manually it works for few days and then suddenly... in the morning I start the car and I see "no signal"...

            Man, optical audio outputs! And High Definition audio!



            Amazing

            I am ordering one... do you know how long we will have to wait till it is avaiable?

              Bad news, not excited about EX anymore

              I am deciding to buy ex15000 but I have a question about audio connectors. At first I was thinking all 6 composite connector are for audio (2 for front, 2 for rear and 2 for sub/center). But I am reading manual rights now, and only 2 of them are audio output (other 4 are video outputs?!)

              Currently I own SP13000 and EN15000 and it is quite common with 6x 3.5" minijacks audio outputs. But I can not imagine how can only 2 composite outputs works as 5.1?

              Can someone explain how it works?
              You are right, there are only two cinch connectors for stereo-out.
              In order to get 5.1 sound, you need to use the digital audio output, which is available as optical and coaxial (cinch) out.
              Modern A/V amplifiers usually have digital audio inputs.
              Oh crap, I have luck that I asked before ordering. I was so excited when I saw 6 component outputs, because I was thinking all of them are audio. I was thinking to replace my existing EN15000 with ex for CarPC use... I don't have amplifiers with digital audio input.

                i had the cn13000 which has the same display chipset as EN. the problem is the same like yours. it is a bug of the bios. my solution is to use XP's default display driver instead of the via driver.

                bios version is 1.07 on my board.

                also via is slow (or incapable) of writing a driver for 800x480 lcd.

                  I have seen this too

                  I have been using an SP13000 mobo for over 6 months and I have had this happen to me about 3 or 4 times randomly. Rebooting the PC clears it up for me, but I have to open the trunk to hit the hard reset button. That is a pain in the boot.

                    I have the same problem. It seems when the motherboard doesnt shutdown properly it tries to detect the LCD at switching on time. I noticed that it reverts to LCD in the display type in the BIOS. My lcd panel doesnt work in LCD mode, only in CRT mode for some reason. I had to revert it back to CRT everytime, till i stopped standby/hibernate and now i just shutdown. This way i find the BIOS retains the display as CRT ... odd i know.
                    cheers.

                      That's exactly the problem!!

                      Sadly, even with the latest BIOS...

                        Ok guys, try this:

                        In BIOS, there is an option "Restore VGABIOS after S3 restore" which is on "Auto". Try changing that to "Off".

                        The above + BIOS 1.09 + the latest vga drivers (22.00.02y) seems to work fine with "CRT + TV" option.!!

                        I tried it about 15 times, with shutdowns, hibernations and restarts, and it seems to work fine...

                        Time will tell!

                          I've got some more news!

                          I received an email from VIA's support about this bug, and their answer was that the types of displays that are selected in BIOS, must always be connected when the PC starts. If they are not, BIOS recognizes it and reverts to another display type.

                          So if you choose CRT+TV in BIOS, make sure that you ALWAYS have them both connected when you fire up your PC.
