Go into the menu and change the HDMI Audio settings - the manual will give you a breakdown on this. HDMI is a little glitchy - if you were using red/gree/blue cables before switching to HDMI, you might want to consider going back to them - just an opinion.

SOURCE: TV shuts off by itself

My first guess is bad connections on the Power supply board or inverter board. Hard sometimes for even a tech to find.

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

Anthony, you did not list a model #. If you would it makes it eassier to determine what may have happened with your Samsung TV. An LCD would start with LN46----.
I have had screen issues with some samsung product. As well as other makes of televisions that use Samsung 46 inch dislay lcd.

We have a Samsung 46" LCD HDTV and a red vertical band has shown up on the right side of the TV screen. Repair or bust?


If the band is there constantly and looking the same then the defect is in the LCD panel itself - the tv is gone.

I have a Samsung Series 6-650 LCD TV (Model # LN46A650A1F). I am trying to connect my Laptop to use the TV as a monitor and have done everything to make it work, using a VGA/HDMI cable, but the TV refuses...


Why do you use VGA-HDMI cable? This TV works fine with VGA cable - it has VGA plug.
Or if your notebook has DVI output, then you can use DVI/HDMI cable and connect it to the TV to plug named DVI/HDMI (only one HDMI input is marked as DVI on TV).
I suppose that over HDMI the TV supports only some standard resolutions, but over VGA it supports almost every resolution laptops use. You can find supported resolutions for each input in the TV manual. Try setting the same resolution on the laptop.
