    Tested my gpu on it = working.
    Tested my CPU i5 520m = no boot.
    Tested i7 on mt old laptop = no boot.

    Does anyone can say if bios for those 2 cpu is same, or different?

    When i was updating unlocked bios on the old laptop, there was no difference nor was spoken about bios/ CPU difference.
    Hi! any luck with this old guy? Have same issue - one day it's just went off and ended with the blinking. Schematics and voltages are ok. perephereal are ok.
    (16f1 i7720qm gx660) charged the battery with external device(was low on voltage) now it powers on, but no picture, no signs of bios initiation.=( any advice is much appreciated!

    What are the voltages you are getting in the inductors? Please upload an image of the mob with voltages in the inductor indicating. Also, upload the schematic in the schematic section. Have you tried using another RAM? Does the reset voltage in the RAM slot represent something

      19 v on inductors. 5 v on bios. FUUUUUUUUUUUUUUUUUUUUUUUUUUUU!!!!1111!!!!
      It's Just Booted up and works as expected. i've been disassambling and assambling it four times!!!11111 am angry as hell.

        So now i'm ok and ready to describe the case.
        disclaimer: I'm not professional electronics serviceman, all i do is for fun.

        I got my hands on 16f1 i7720qm gx660.
        Symptoms: notebook worked fine till it was abandoned for couple days when it went off and never turned on.

        it showed red battery indicator, power on button lightens for couple seconds and silence.
        The notebook owner purchased a new battery installed it with no effect.


        The notebook was in service earlier with typical power connection faliure - flexible wire was soldered to plus connector and it worked fine for a while. So i cheked the input chain and found no issues.

        With new battery installed i've changed CMOS battery to new one and that's didn't work either.

        I abandoned the device for couple months till i got time to get back to it.
        So i disassambled old battery and charged it directly with usb module.
        When battery was installed notebook showed signs of being alive (it reacted to powerbutton, fan went crazy, but no visual neither on build in screen nor via hdmi)

        i checked currencies, it had 19v on coils near processor and 5v near bios, but video was cold.
        I played a bit with disconnecting memory modules.
        Than i took out CMOS battery and left it for a while minding my business.
        When i came back to it, and tryed to turn it on to perform more measurements it just booted up. IDK what was that, but now it works as expected for 24 hours allready.

        P.S. I could not find any schematics for this motherboard, so if anybody could help with it, I'd be grateful. (I still want to figure out what the hell was that=)

          Powersupply has all the voltages - Monitor still no power
          by Capacitorial
          Hello guys,

          I have a Philips 240B7QPJEB. The monitor seems completely dead.
          I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
          On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
          The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
          The weird thing is, that the Power LED is powered over the TCON board.
          On The TCON...

          Hello members.
          I got my gx660 for a long time and it was my backup laptop for 2 years. It was working splendid so far, and one day just didn't post. No backlit no hdmi no vga.

          Specs are:
          MS16F1
          i5 460m
          2x4Gb samsung RAM
          HD5870
          SSD + Hdd

          Current state:
          When i press power button, the button itself blink once, and after 6-7 seconds, it is lit normally , fan spins, CPU and GPU get warm, even fan is changing speeds ,it is monitoring the temps. Nothing on screen, no backlit, nothing on hdmi and vga. It is not booting, i waited...

          Help reading schematic voltages input/output
          by gjgib
          Hello, this might be embarassing since I consider it a dumb question but keeps me kinda stuck sometimes in my journey.

          I want to know if there is any post in this forum which explains my questions. A) When, where and how do I know when X voltage line is input or output. Example:


          I'm battling with this IC to understand it's voltages. It's from non-turning-on Lenovo Ideapad 3 15iil05 - NM-D461.

          I see some lines like +5VL / +5VALW / V9B+ / +3VALW being okay and some others like 1.8VALW / +0.6VS / +2.5V_DDR. I just know that some of them are bad or missing,...

          HISENSE LCD LED TV MODEL HX40N2176F LED DRIVER SN51DP IC PINOUT AND VOLTAGES
          by RossMoodley1967
          Hello

          Need to know the voltages that will be present on SN51DP ic when tv is in standby and when powered on.

          Just to elaborate on the problem with the tv 1.set came in with flash of HISENSE logo on screen then back into standby.2. Now tv when plugged in red standby light present to quickly changes to blue but no backlights.3.Then an hour ago i checked again , came on standby and stayed until i pressed the power button which changed to power on (blue)4.As far as the led driver circuit goes voltage at output in standby was 38v , power on led light up voltages rise 58v-68v...
