    Sanyo lcd dp46840-00. Green light on and off

    Sanyo dp46840 turns on green then off no audio or picture.the green light gives you 3 chances and then no light, need to unplug ac and replug so it gives you the 3 times green ligth.....I check the voltage on the star marked on the main board.....
    9v gives me 9.6v...3.3v=2.7v....1.0v=0.00v....p12orp15v=7.8v...p5v=5.67......audio_pow13=5.5...any ideas

      We are going to need hi res, straight shot pictures from your boards. We also need to be able to see the pin outs on the power supply to the main board.

              I have had this problem before with this TV. You have a bad mainboard. The voltage drops you are getting are caused by the shorted mainboard.

                                          Hi

                                          Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

                                          Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

                                          The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

                                          I have already tried replacing all of the...

                                          820-2610-A Sys onewire help, no green light. Please help from the gurus

                                          Hi

                                          I have an 820-2610-A motherboard that has no green light.
                                          I have noticed is when I do a SMC reset the light on the Magsafe blinks.
                                          From My understanding, the sys onewire circuit is responsible for the green light on the magsafe
                                          The sys onewire circuit on this model and others is more involved
                                          I was hoping if anyone knows about this and how it works, can reply and let me know
                                          I know this is an old model but I am sure there are people who still works on these or knows about them

                                          Hi guys,

                                          I have this 2011 MBP - the company I was working for, bought it at the time for a project and gave it to me after that. Later on, I gave it to my daughter which used it for normal internet browsing and office apps. At some point the, now famous, AMD GPU issue hit this laptop as well. I disabled the use of the AMD GPU following some information I found at the time (the one that, at the end, one moved AMD kext drivers to a backup location). So the laptop was using the CPU graphics and it was ok for the said daily usage. I even replaced the drive with an SSD one and it was operating...
