13、 BOARD FUNCTION CHECK 1. Image reverse check: press “reverse display” key on key board, the image on TFT panel can be 180 reversed. 2. NTSC / PAL switchover check: switch NTSC / PAL system by remote, there are a abviously color change on TFT panel, but the color change can not be colorless. 6 TROUBL

14、ESHOOTING Item Symptom Cause and Remedy 1 No power Check if power plug is properly connected. Check if there is power at the AC outlet by plugging in another appliance. 2 No picture Check if the TV is connected and switched on. Select the correct AV input on the TV. Check the video connection. Check

15、 channel selector is set to AV on the TV (See your TV manual for instructions). 3 Distorted picture Check the disc for fingerprints and clean with soft cloth, wiping from centre to edge. Sometimes a small amount of picture distortion may appear. This is not a malfunction. 4 Completely Distorted pict

16、ure The disc is not formatted to the TV-set used (PAL/NTSC). 5 No color in picture (when connects to TV) The disc is not formatted to the TV-set used (PAL/NTSC). Ensure DVD Player is not connected through VCR. 6 Disc cant be played Ensure the disc is label side up. Clean the disc. Check if the disc

17、is defective by trying another disc. 7 No sound Check audio connections. Make sure the sound setup of DVD disc is correct. 8 No return to start-up screen when disc is removed Check to see if the program requires another disc to be loaded. Reset by unplugging the player from the power supply, the con

18、nect the power supply again. 9 The player does not respond to the remote control Aim the remote control directly at the sensor on the front of the player. Avoid all obstacles which may interfere with the signal path. Inspect or replace the batteries. 10 No audio at digital output Check the digital c

19、onnections. Check the digital out menu to make sure that the digital output is correctly set. Check if the audio format of the selected audio language matches your receiver capabilities. 11 Buttons do not work Unplug the player from power outlet and reconnect after a few seconds. 12 You have forgott
