    Board shutting down when using cooler with higher pressure

    I have this board, ECS K7VTA3, it was running fine after recap. However the guy I've sold it to brought it back because of shutting down within 5 secs after powering up. We were playing with that for some time and discovered it only happens when we use cooler with higher pressure.

    Any idea where the problem could be? Some kind of cold soldered joint? We tried two CPU's so probably the problem is in socket or somewhere near.

    Re: Board shutting down when using cooler with higher pressure

    This is some insane crap! I found the problem. It is in some mentally ill thermal protect. As soon as the board does not detect fan runing at some maniac speeds (4k RPM or so) it shuts of automatically! Holyl crap. I'll try newer BIOS, other choice is only to connect some voltage at the sense pin for foolign it.

      Just connect some fan to 12v from the power supply and run the sense wire down to that connector.

        Nah it'll be loud.

        Anyway the board is out of service now due to bad flash. These ECS suckers are even not able to write down the right version, there is 1.0 next of the model number but 2.0 in the corner which is probably true since from v2.0 the board is violet. I flashed v1.0, two block were flashed badly and it doesn't boot now. I'll have to leave that until I'll discover similar board where I can flash the BIOS chip in.

          Been there, done that. Just get another brand.

            Oh, that's sweet.

            I remember the fan protection on some asus board.

            Fan failure shutdown - Enable (We were trying to play safe, so why not)

            Just that we noticed, BIOS monitors _ALL_ fans, not just the ones that are currently working. So, with no fan attached BIOS read 0RPM ...
            Had to reset bios to fix it !

              Re: Board shutting down when using cooler with higher pressure

              The problem is I cannot disable that The board seems good beside that so as I said I'll wait for another one bloated K7VT3 and try to swap the BIOS chip while running than flash it.

                with flashrom, you can use any board (that physically fits the ROM chip).

                  Re: Board shutting down when using cooler with higher pressure

                  Oh thankx! I already tried but AWDFlash still refused to flash due to system config incompatibity with the binary file. I'll try at evening.

                  If the problem was not bad BIOS file but damaged chip, is possible to reflash BIOS from other board with this program and use it here? There is typical PLCC with Phoenix.

                    Re: Board shutting down when using cooler with higher pressure

                    i can try to modify the BIOS file if you want.
                    sort of like what i did with Maxxarcade's Shuttle board (thread on here somewhere).

                    un-hide settings and stuff..

                    oh and you can use Uniflash to try and hot-flash the BIOS file to the chip on a different board.

                      I'll try flashing back the original backuped BIOS file, than if BIOS for PCB 2.0 if I'll succeed. Thanks.

                        Re: Board shutting down when using cooler with higher pressure

                        I've reflashed the original backed up BIOS, still nothing so tried also the official BIOS for board v2.0. After oned dead CPU (some shit on cooler made it overheat probably) the board posts fine. The problem is it talks some shit about no keaboard preset and do not respond to pressing anything - tried two PS/2 keyboards, both blink during starting, both working elsewhere. Gonna for USB keyboard.

                        ADD// tried USB keyboard, no message about no keyboard detected, but it still do no react to any key in any way. WTF?

                            I'll ask arround for some. I measured the fuse near ports and it's fine. Could this still be bad BIOS? I can keep the board at least for testing processors, you know, when it posts, CPU is working. Maybe memory, with autoexec for memtest from floppy. But that's everything I can do with this board. So much time and money in caps for almost no functionality. Damn it.

                            It still does the stuff with cooler, I'll probably solder resistor between 12 V and sense on the fan connector directly on the board. Would 470 ohm be enough? I have such a SMD.

                              I would check for burned power connectors.

                                by Tynan Dill
                                I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                Upon bringing it home and plugging it up, it showed a standby light.

                                I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                Problem

                                This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                                Hi There,

                                This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                                After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                                Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                                Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
