5. Is the "Status" LED flashing a pattern of yellow and red lights while the
"Power" LED is steady red? This pattern indicates an internal system error.
If the problem persists contact a qualified Electrohome service technician.
6. Was the lens cover accidentally left on? Remove lens cover.

1. Does the green "Status" LED flash each time a key is pressed? If not,
Vista
10K is not receiving the keypad's IR signals. Ensure the keypad
GRAPHX
is pointed either at the front or rear of the projector, or at the screen.
2. The viewing path between the IR keypad and the projector (or screen) may
be blocked. Ensure there is a clear line-of-sight between the keypad and the
projector (or screen).
3. The batteries in the IR remote keypad may be weak. Refer to 4.3, Replacing
Keypad Batteries for instructions on how to replace the batteries.
4. There may be unusual lighting conditions in the room affecting IR keypad
operation. Determine if such conditions exist and correct.
5. The IR keypad may have been disabled for use with this projector(s). See
2.10, Keypad Protocols and 3.7, Adjusting and Checking System
Parameters.

1. The projector probably became overheated. Allow to cool and make sure that
nothing blocks projector vents. Do not operate in environments warmer than
40°C (104°F).
2. The lamp may have reached the end of its 1000-hour life. Check the Lamp
Hours entry in the Status menu. Replace the lamp assembly as described in
4.4, Replacing the Lamp and Filter.

1. If the display is jittery or if it disappears and reappears erratically, check that
the source is properly connected and that its signal is of adequate quality for
detection. For example, the projector scans the default input
signal to display. If a poor quality or improperly connected source is
connected, the projector will briefly and repeatedly attempt to display an
image. If no source is connected, the "No signal present" error message
appears over a blank display. Correct the source connection.
2. The horizontal or vertical scan frequency of the input signal may be out of
range of the projector. Refer to Section 5, Specifications for scan frequency
ranges.
3. Sync signal may be inadequate. Correct the source problem.
4. The input signal type may conflict with the input module. Install the correct
module to match that of the source.
5. Pixel tracking and phase may need adjustment.

1. Brightness and/or contrast may be set too low. Increase the brightness and/or
