Where do I hook up my surround sound

Hello, this set has only a USB jack that can be used for audio output, but that is the only output on this set. If your receiver doesn't have a USB jack, the satellite box output is your only solution. thanks,Terry

How do I troubleshoot my Samsung TV? I have sound, but no picture.

Caps can fail with no outward signs. It takes a special meter to test them. Your set may have a back light inverter that powers the back lights. When it fails, the picture cant be seen, but you have sound, to check this look for a picture on the screen using a flashlight

Why dont i have a picture?

Hi, not sure if you have the same fault as i had, but our tv only had half the screen go off, after looking up on the internet i found a video for a fix, what you need to do is remove the back cover, there will be ribbons that go from the front screen to the main panel, i removed each one at a time and rubbed the contacts of the ribbon with a rubber on the end of a pencil, plugged them all back in and switched it on and it was now spot on, thats more than a year ago and its still working spot on, hope this helps jim

Half of me samsung lcd TV screen is shadowed with light streak going across top of screen

Sounds like the LCD Panel, if under warranty contact Samsung warranty for service. If out of warranty, watch it until you tire of it then replace the unit as the cost of a new panel is more than a new unit.

Samsung TV won't turn on after lightening storm. Surge protector "sparked once, but all the other things plugged in are operating.

Contact your insurance company and make a claim. Lightning damage to electronics like that is hard to repair.
