ProblemPossible Remedies
I cannot get Twin View to workIf you are using a cable box to unscramble all channels (as shown on page 30), you cannot use the Twin View feature. This is because the cable box can unscramble only one channel at a time.
You can use Twin View to view a signal from a different source that is connected to the LCD projection TV’s A/V jacks (such as a VCR or DVD player) in the second window by pressing V/VIDEO while in Twin View.
Sources connected to the CABLE, VIDEO 5, VIDEO 6 and VIDEO 7 inputs, as well as digital source display in the left Twin View window, but not in the right.
There is no Twin View window, or it is just staticBe sure the Twin View window is set to a video input or channel that has a signal airing.
You might be tuned to a video input with nothing connected to it. Try cycling through the video inputs by pressing TV/VIDEO.
Twin View cannot display anything but TV channelsTry cycling through the video inputs by pressing TV/VIDEO. Check that the >el option is not set to Skip. (See the Setup Menu on page 102.)
Twin View displays the same program in both windowsBoth Twin View windows might be set to the same channel. Try changing channels in either window.
Remote control does not operateThe batteries could be weak. Replace the batteries.
Check the orientation of the batteries.
Press FUNCTlON repeatedly until the TV indicator lights up. You may have inadvertently pressed FUNCTlON, which changes the remote control to SAT or CABLE mode.
Make sure this unit’s power cord is connected securely to the wall outlet.
Locate the unit at least 3-4 feet away from fluorescent lights.
Cannot change channels with the remote controlIf you are using the LCD projection TV to change channels, first press FUNCTION repeatedly until the TV indicator lights up.
If you are using another device to change channels, be sure you have not inadvertently switched your LCD projection TV from the channel 3 or 4 setting. Use the Channel Fi option to “fix” the channel based on the hookup you used (see page 96).
If you are using another device to change channels, be sure to pressFUNCTlON for that device. For example, if you are using your cable box to change channels, be sure to press FUNCTION repeatedly until the SAT/CABLE indicator lights up.
Remote control does not operate non-Sony video equipmentIf you replaced the batteries to the remote recently, the code numbers for the video equipment may need to be reset.
There may be more than one code for the equipment that you are attempting to operate.
There is a possibility that some non-Sony equipment cannot be operated by your Sony LCD projection TV remote. You may need to use the equipment’s original remote control.
Image does not display/Cannot see all filesSome variations of MPEG 1 movies may not play back correctly.
Make sure the image file is a JPEG ( jpg, jpeg) file or an MPEGI (mpg, mpeg) file
Make sure the Memory Stick is inserted properly (see page 66).
Check the Filter option setting (see page 77).
Check the Select Contents setting (see page 77) and ensure that files are either in DCF directories if Digital Camera Folders is selected (see page 77), or in the currently selected folder if Select a Folder is selected (see page 77).
The maximum number of files the Memory Stick Viewer can display is 1,024.
JPEG image displays undesirable motion or flicker in full screenJPEGs captured using a digital video camera may appear to display motion in full screen. This is a result of the way digital video cameras record still images, and is not a result of a malfunction with the LCD projection TV.
Rotation not saved after Memory Stick is ejected or Memory Stick Viewer is closedThe Memory Stick might be locked. Unlock the Memory Stick and try rotating the image again.
The file might not have information (EXIF data) that is usually generated when a digital camera records a photo. In this case, it is not possible to save the rotation. There might be insufficient space on the Memory Stick to save the rotated file. Try deleting one or more files and rotating the image again.
Cannot show (or hide) file information in full screen or Slide ShowSet the File/Information option to On or Off (see pages 72 and 75).
Cannot see menuPress Up arrow to display the menu again.
Cannot hear audio while using Memory StickCheck the LCD projection TV’s volume or Speaker (page 93) settings.
