My Viewsonic N3752w is not working. First it would not turn off - all of the buttons on the TV, including the power button, would just bring up the start menu. I unplugged the TV, and now it will not turn back on. The red light is lit - indicating power. Any idea what it could be, or what I should try? Thanks!

You may have bad main logic board, http://www.shopjimmy.com/catalogsearch/result/?q=n3752

The back light is working for sure, you may want to check if the Power supply on signal goes to 5v when you push the power button.

If you are going to DIY and have proper tools and know safety precaution then please read on:

We have the same problem with ours. I'm suspecting it's the power supply board. I'm going to order a new one, swap it. That should fix it, I suppose.
