Piture is not using the whole screen, just in the center, dark on the edges

There may be screen damage and that entire part of your screen may just contain dead pixels.

LED damage need to replace

You may want to remove back cover and wipe/clean the three large black lens.

Also go to an unused video input and examine screen; Same problem?

Let me know what you find.

Could be an LCD panel needs replaced.....very pricey, unless it is still under warranty!

The screen could not have shifted only for one game or prog. It may be larger on all side and you notice it during the game when you want to access the buttons. So, press the settings button and reduce the screen size to occupy the whole physical screen (ie, max and no more). Now you will get the whole picture on the entire screen.

bad panel

there is a part inside the engine(the part that produces the picture) that is a mirror tunnel. The actual part name is "light tunnel" this tunnel takes the light from the bulb and compresses it into a smaller beam of light that is then shined onto the DMD(million mirrors) this produces the picture on a DLP TV. this mirror tunnel is glued together on all edges. One edge of your "light tunnel" has started to come unglued and has slipped a little. This causes the slightly dark area usually on the left side of the picture that you see. the light tunnel can be replaced as a single part. much cheaper than replacing the whole engine.

You have a backlight problem. Check your backlights if busted or if it has supply voltage... ^_^

An adapter tube has to flare out at the end or it will cut the corners off at the wide angle setting. Telephoto should be ok though.
