    Post a picture or two.
    Just because the caps look good doesn't mean that they are, especially if they are a non-Japanese brand.
    What's the brand of the PSU you are using.
    CPU and RAM specs? Check with the motherboard's user manual to make sure you haven't missed something, like hardware incompatibility with the components you are using.
    Does the board beep with no RAM? (make sure you have a PC speaker connected to the header)
    Reset CMOS and check CMOS battery voltage already?
    Have a PCI POST card handy? Most old motherboards will show activity on it, if they are not completely dead.

    *EDIT*
    I see this is a newer AMD motherboard with an ATI chipset. Thus, you could also be having a BGA issue. Most likely the ATI Northbridge, but also possibly the CPU socket if a stock warp-a-ton AMD heatsink was used. In either case, then the board would need a reflow. But first check the above items.

    Another thing worth checking is the LAN chip and LPC SIO - does any of them get very hot? If so, the motherboard may have been a victim to a lightning strike.

        You cannot test the board without CPU. If you do, you won't get any beeps or any meaningful results, so don't do that. Always test with a CPU *and* CPU heatsink installed... with thermal compound! I know some people skip that because it saves time, but it can also damage the CPU or cause the board to panic when the CPU throttles, and thus not POST. I used to tell that to my coworkers all the time and they never listened 'till all of our test CPUs went bad "for no reason" or "out of the blue", as they said.

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          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.

          Assuming...

          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

          TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
          by howardc64
          All left and right refers to looking from rear of TV (or looking from front with TV upside down)
          • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
          • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

          HELP! A1398 Dead,
          by Fam787
          I bought a second hand Mid 2014 A1398 MacBook Pro when I lived in Australia. I'd bought it as a back-up machine because I had a Mid 2014 MacBook Pro, and realising it might one day fail, I wanted a backup machine because I don't like change.

          Two weeks after buying MBP2, the seller called me to check if everything was OK with the unit, which I thought was odd. At that stage I might have turned it on a couple of times, but I'd not used it when he'd called. Over the last few years I used the machine seldomly because my original mac has been pretty OK. Every 3-6 months I'd charge it...
