    so with no short it went through it's normal startup blinking (green) then locked on solid green which is what I'd expect with that procedure I suggested and would mean it's on and running able to test voltages.

    but if it is shorted vsus and he has and both sustains isolated but same result then either the vsus is shorted at the p board or leaves the result as A board as per the flowchart.

    Am I on the same page or offtrack here?

    Are you still suspecting sustain boards?

        If there are no dead Vsus/Vda shorts I would say A board is a good possibility.
        Worth eliminating Vda too just in case panel is shorted (rare, but I've seen water damage do it)

            well im glad that i have a problem that has not been covered, or am i, im just going round in circles, still can't find a short on SS or SN,
            after the flashing green LED, has stopped, there is no repeat of the flashing or dull lite LED,
            think this is another ebay job,
            but i'll have another go later, just incase i have missed somethink,

                Lenovo Y700-17ISK turn on and off
                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...

                Panasonic SA-BT203 Power Switch Clicking Won't Turn On Issue
                by platinumsteel
                Hi guys I have a Panasonic blue-ray disc player Surround Sound that is giving me a lot of headache trying to repair. When i press the Power button it gives a Click Click sound but doesn't turn on.I checked Power Supply Board for swollen or bad ESR caps with my ESR Meter and all i found was some swollen caps on the Audio Board i changed with new caps but still the same. Checked the whole board for shorts and there isn't any.I used to have like 3.3v on the Power Switch Button but now i have 20v ... Is that normal? isn't it supposed to be 3.3v on the Power Switch? I am hoping you guys might be able...

                Panasonic TX-55EZ950E wont turn on
                by Trol
                Hope you can help me

                3 weeks ago my Panasonic suddenly blinked red in the power led. So I tried to turn it off and on with the remote, no luck. I then turned it off via the power outlet. After that I tried to turn it on again, but nothing happened. No lights and no picture or sound.
                Now I have tried different solutions, taking the power for 1 hour - taking the power for one Day - changing power outlet - holding the buttons on the TV down for several seconds, and even minutes. And nothing seems to help, the only thing that happens is that there is a sound, like a relay...

                MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
                by RdeveLabs
                To all the members here...

                Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

                So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...
