Hello,
Purchased a broken Samsung UN39EH5003FXZA (Version CD01) to have fun fixing. When I first acquired it, I did not connect any video signals and only plugged it into the wall. The unit booted and showed the βno signalβ window and I could navigate all menus and change sources. I unplugged it, connected my over-the-air antenna to the coax, powered it on, got the unit to scan the HDTV channels, and I think then the TV self-shutdown with the melody. When I powered back up (melody), it would show the channel selected on the OSD and after a couple of seconds, it self-shutdown... -
I have this machine. It powers up and gets fan spin, will even shut down when I hold the power button.
U1200 gets very hot under thermal camera, the next hottest region is UB000 and L7030. I'm assuming L7030 is warm due to charging.
Do I have a potential dead CPU? or just a dead U1200? Not sure what to check since everything is powered up. -

Hello everyone.
I need help with my Yamaha MSR400 - Powered PA Speaker that I bought it used recently.
It is power on, and sounding good / working perfectly fine. However after 3 - 5 minutes, the heatsink is starting to get warm, and it smells burning a little bit.
I did tried multiple times on different day, event the speaker is not playing any song (input does not connect to any source, and the volume level is zero), after it turns ON, 5 minutes later, the heatsink is starting to get warm, and it smells burning a little bit. I am afraid keeping it ON longer than 5 minutes... -
Recently had my bedroom Vizio D40u-D1 apparently die while it wasn't being used. Noticed the power LED flashing, figuring maybe a software upgrade, but attempting to turn it on proved that wasn't the case. When powered on, the power LED will flash a bunch of times after about 2 minutes then turn off again. Definitely is no picture even with a flashlight on the screen. Had the opportunity to open it up over the weekend. Doesn't apper to be anything out of the ordinary visibly inside, nor any odd smells of escaped magic smoke. Readings from the connector in the corner of the power supply board...
