  • Page 31 Typical maintenance samples Example1 [Symptom]: After the player is powered on, DVD or VCR indicator will keep lighting. The buttons don’t response. [Analyze]: Power supply is normal, but the system program doesn’t work normally, and so does the CPU (IC601). No signal is output at testing switch (P606) on , and running mechanism no lifting voltage is output.
  • Page 32 Symptom Remote control doesn’t function, instead the player still works by pressing buttons on the front panel. [Analyze] Remote sensor and the circuit have trouble. First test if +5V voltage output at remote sensor P701 with OSC. Then test if pulse signal output at output terminal on remote sensor, if not, the remote sensor, the remote sensor has broken down.
