IF signal from TU101 flow through to pin 63, 64 of IC501. The video detection circuit in IC501 will be detect the video signal from IF signal and then send it out by pin 60. The video out from pin 60 will be return to IC501 again by pin 56 and we're can call this signal is "Internal Video" 2. External video is the signal from external equipment, such as VCD, or VCR. Rear A/V (JA01) and front A/V (JA02) is same line circuit but, JA02 has the internal automatic switch on/off. When you put the A/V pluck to JA02 and JA01 in same time. The IC501 will be receive the signal and flow through to pin 54 from JA02 only. 3. Internal signal and External signal will be joint together at Video switch circuit in IC501. When the user select the input signal (by press TV/AV button on the remote control or submenu on the set) and then the video switch circuit will be select the signal follow the user selected. The signal after selected will be send to video processing circuit and pin52 (video out for JA01) 4. After video processing circuit complete process, the signal R, G, B will be send out from pin 12, 13, 14 of IC501 to video amp circuit before sent to CPT.
