Don't skimp on details if you need help in a public forum. Everyone's AV systems are different. Be very descriptive with all makes/models, etc. Knowing your cable provider would help too.
I am a novice. I bought my first flat screen tv, Vizion 37 inch M series with wireless internet. I plugged my old tv into the cable box and it has 2 prongs, my Vizio has a 3 prong plug. How to I connect to cable if I can't plug my tv into my cable box?
Also during setup for internet, I have to use the on screen keyboard to put in my security code for my network. Where is the onscreen keyboard? Thanks.
