Re: LG 27up600-w

Unfortunately, LG messed up this monitor real bad, I believe they accidentally shorted the 5V bus and 3.3V bus together causing all of the chips designed to run at 3.3V to run at 5V, which is well over their absolute maximum limits. The first chip fried for me was the audio output chip, so one day I suddenly got no audio. The second one fried was the main chip RTD2595LT. This is game over when I no longer can power on the monitor.

If you trace the board, you'll see R155 and R156 right next to the buzzer. R155 is connected to the buzzer and 3.3V bus....
