With the Samsung PPM42S3QX Power Supply Board is the likely the cause. Testing and diagnosing - Remove the back of the TV and check the voltages on the power supply. The output voltages will be labeled on the board. Look for obvious need for replacement such as swollen caps, bad fuse, burnt components.

Monitor picture fades out.


I thought my problem was originally monitor related. However since I posted, the picture disappeared altogether, and my PC wouldn't even start to bootup. Fearing my mobo may have died I removed the hardware components, cleaned then re-assembled them. After all that, it turned out that my graphics card has a tendency to become slightly unseated. Once I was aware of this problem booting up resumed normally. It seems that the problem of the fading monitor picture seems to still occur, but soon after I use the machine after 'hibernation' state, and even then it doesn't always occur if I do use hibernation. I haven't used hibernation for a little while and so far the problem has not returned

How di I get my K850i to show the time in screen saver mode


Press the volume button on the side of the phone to display a screen similar to previous Sony Ericsson Cybershot phones during standby mode. It will display the time and a message icon. This is probably an energy saving feature when the screen goes black in standby mode, but you must press the volume button to get to that screen.
