Home theater projectors collocation projection screen, with the signal input, can replace the TV, set-top boxes, give you the enjoyment of theater stage. But due to the particularity of equipment, operation always is not so convenient. We are all familiar with the TV Detailed to introduce the home theater projectors signal problems when processing method, this article will continue to share the image problem handling skills.
Phenomenon 1: no images, no sound
The reason:
1. Determine the home theater projectors signal source in accordance with whether you want to access to the source.
2. Whether it is right connection home theater projectors and signal equipment.
3. The cable is damaged.
4. Have the image will have you access the audio sound output. (the speaker will have sound output)
Phenomenon of 2: no color images
The reason:
1. The poor quality of home theater projectors signal source.
2. Home theater projectors signal input interface connected with the output of the signal source equipment interface is correct. Y (such as: the color difference signal received AV input port of home theater projectors can cause image colorless)
3. Check the menu "colors" option is parameter setting is too low.
The phenomenon of 3: image color
The reason:
1. Check the home theater projectors the "tone" parameter Settings menu option parameters are adjusted. (color is refers to the types of color if the parameter is set too big or too small will cause partial color image).
2. If the parameter is set of home theater projectors right or partial color, will replace the decoder board or the adapter plate.
There is interference phenomenon. 4: the image
The reason:
1. The poor quality of home theater projectors signal source, or the signals are weak.
2. The line is too long, or the poor quality of signal lines. (can be an external signal amplifier reinforcement signal)
3. The signal lines and other equipment line bound to go on line. (belongs to line the mutual interference between installing a home theater projectors signal lines long, please use the shielded wire with better quality between the lines to go alone to eliminate interference)
The phenomenon of 5: image fuzzy not clear
The reason:
1. The newly installed home theater projector may be not focusing lens. (please rotate around the lens adjust the picture clearly)
2. The projection images or big or too small, is beyond the scope of home theater projectors projection. According to the physical machine, with reference to the instruction properly installed home theater projectors.
The phenomenon of 6: a trapezoid
The reason:
1. The picture appear inconsistent size up or down, can through the home theater projector keystone correction function, on the picture. If home theater projector keystone correction function, can't picture of trapezoidal correction, is the machine installation Angle is too large. (please refer to the description of the projector installed, adjust the home theater projectors.)
2. The picture appear inconsistent about size, as a result of home theater projector lens surface and is not caused by the parallel between the projection screen, can be achieved by swinging the fuselage, see images about the same size can.
Phenomenon of 13: HDMI no display, no voice, images flashing
The reason:
1. Home theater projectors didn't choose the right signal input correct selection signal source (see instructions).
2. The source version is too high (in the low version of the signal test).
3. The images flashing, is likely to be poor contact hd interface (replacement tablet).
4. HDMI bad or poor contact (change the HDMI line).
The phenomenon of 7: connect the computer shows no signal
The reason:
1. Home theater projectors signal source is correct mode switch to the computer.
2. Connect the home theater projectors and computer VGA cable is connected well.
3. The computer's screen resolution and screen refresh rate is set too high, please set up in 800 x600/60 hz).
4. Pick up the laptop, to set, notebook display output is the function key "Fn F?" Switching laptop display mode.
5. The above 4 points out no problem, we should find a display confirmed the presence of signal output. Computer have signal output means that there is something wrong with the projector, to replace the decoding board or a tablet. Vice will check the computer's graphics card or driver if there's any problem.
Phenomenon of 8: color bar appears on the screen, the screen
The reason:
1. The adapter plate is faulty, replace the adapter plate.
2. The decoder board is faulty, replace the decoder board.
