    HP P6310T will not turn back on...Help please

    The issue started when I plugged in a phone to usb to get pictures and the computer usb failed to recognize the phone with several attempts.
    I clicked on windows 'restart' hoping it would reload drivers and work but I never got that far.
    The computer appeared to 'shutdown' on the restart except the power supply fan was still running. It appeared dead except the ps fan. Like the computer got stuck/froze before it rebooted(no picture, black screen).
    I let it sit several minutes and finally unplugged the power cord.
    When I plugged it back in the computer will not power on at all no lights(in front) and no fans come on at all but I have a solid green power light on back of ps.
    I disconnected ps from computer and jumped the green fan wire to ground and checked all voltages were good(11.48v - 5.09v - 3.336). The plug for processor power has 2yellow and 2 black wires. Both yellow were 11.49v and black 0v.
    So I think I confirmed the power supply is fine. If i am in error please shout out.

    At this point I am trying to isolate where the problem is. Possibly the startup circuit? or does this sound like symptoms of a fried processor?
    Again, it is dead except for the solid green light on the ps.

    Numbers I pulled:

    Motherboard- H-IG41-uATX

          I need help with my friend Sony GDM-FW900 24” CRT
          by matthewmcconaughey
          Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

          I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.
          1. It started with a bright and greenish picture upon starting a cold monitor.
          2. About 2 years ago, only on the cold boot, the screen started to occasionally flash with

          Asus X453MA won't turn on and green led light blinking
          by jxrepman
          Hi there,

          I have this ASUS X453MA Laptop that's not turning on. When I plug in the charger, the green light just keeps on blinking and pressing the power button does nothing.

          I have checked the charger and it is giving 19+ V

          I have disconnected the battery and pressed power button for 30 seconds.

          I tried another RAM stick.

          Tried disconnecting the keyboard and touchpad.

          Tried disconnecting the HDD and the wifi adapter.

          The problem persists.

          Hope you could help me out on this one. Thank you.

          LCD TV Green/Pink screen problem
          by jimjoe123
          I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

          Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

          Then each time...

          by pajdek
          Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...
