Why isn't my TV turning on? LN52B750U1F

by tellahoohooo / November 17, 2011 6:31 AM PST

I attempted to plug my computer into the TV via MiniHDMI > HDMI port.

As soon as I hit detect on my computer for a new monitor, the Television started to flicker, then went completely black. Now it is completely unresponsive. As soon as I plug the TV back in the red light on the front turns on and then nothing. No response to hitting the power button on the TV or on the remote.

Did my TV break because I tried to plugin an HDMI cable?

I have contacted Samsung. I'm 8 months out of my warranty so they won't honor it however they did say this.

"Nothing you plug into your TV should harm it" (In context she meant nothing I try to use the TV as a monitor for should harm it. If it wasn't going to work "It wouldn't display anything but should continue to work."

I've got a tech coming on saturday, but I'm not sure how excited I am about that considering the "most" it will cost me is half the cost of purchasing the TV. I'll update once the tech lets me know what happened.

I was able to get the TV repaired, turned out to be the main board that needed to be replaced.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
