The power went off today for unknown reasons at my house while I was watching my LG TV through my LG LHB335HTS which is hooked up with HDMI Cables. When the power came now it will not show a picture...

I was able to fix this issue by changing the screen resolution to auto on the home theater system. Since I had no picture on my tv, I had to unplug it and plug it into another tv. Once connected to the other tv, I was able to access the menu and change the resoultion to auto (it had been reset to 480dpi, this is why it didn't work on my main tv). After I set it to auto, I was able to get it all to work. My niece had been playing with the button in front of the device and apparently the sequence of opening the DVD tray and pressing the stop button causes the screen resoultion to reset to 480dpi.

Picture on my Bose Lifestyle 35 is jumping around

Replied you on premium post as well.
Please change TV color system to AUTO to see jumping free picture.
If Bose is either on PAL or NTSC color system, TV will show correct picture and color automatically.

I'm not getting any color pictures in my home theater system

Well, assuming were talking about a dvd player with dvd's,you dont specify what type of cables you are using to conect it to your tv, it appears that it has something to do with Progressive Scan been turned on. Progressive Scan is a feature built in your dvd player, wich by using it, it would give you a better picture//resolution on your tv, you need to use Component or HDMI cables to hook up the dvd to your tv if you want this settings, but if you are using composite RCA cables (Red,White & Yellow) and the Progressive funtion is turned on by accident, it may give you a split screen, black & white, or no picture problems. Also if you are using Component (Blue, Green & Red) cables, if one of them is unplug, the picture can be out of colors, or no picture. Check this things, if not, write back with more details about your set up.

Get sound but no picture

Plug the yellow RCA cable into the Video Out on the 3 2 1 and into one of the Video In ports on the tv. Make a note of which port you plugged into. Then change the input selector to that video port on the tv.

Showing red image

Make sure red is matched up to red, green to green, and blue to blue first. Then, try a different set of YPbPr (component) cables if you have a set available. If it still shows up red, then read this:
If you are using a Progressive Scan TV
(TV must indicate Progressive Scan or
ProScan capability), to activate TV
Progressive Scan, please refer to your TV
user manual. For DVD system Progressive
Scan function, see page 28.
Helpful Hint:
– If your TV does not support Progressive
Scan, you will not be ab le to view the picture.
Press and hold OPEN/CLOSE button and
press ‘1’ to deactivate progressive scan.

Progressive Scan - turning on/off
To select this item, you must set “Video
Output” to Y PR PB and ensure that your
TV has progressive scan (See page 11.)
Follow the steps of “Using the Setup
Menu” and select :
Select this to disable Progressive scan

These are pp. 11 and 28 of your owner's manual for the HTS

If these methods still fail, try turning your TV's progressive scan off or on.
