    Lg 50pg20 won't turn on

    Hi, I have an lg 50pg20 ua that has a power issue when the power button is pressed it flashes blue 3 times then back to red, I took off the back and checked the ysus and zsus boards as well as the main power board and all
    capacitors are fine no bulging or oozing, now when I unplug
    the ysus and zsus boards the TV stays on but when one is
    plugged back in it goes off again, suspecting a bad power
    board. Thanks

              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.

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...

              This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

              I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

              I am comparing them to a brand new one that I installed

              The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

              I going to let it run for several days before I remount back on the wall next to the...
