CP-530 Service Manual
2 SAFETY INSTRUCTION W ARNING: Only competent service personnel may carry out work involving the testing or repair
of this equipment.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high voltage must not exceed the specified limit. The nominal value of the high voltage of this receiver is 28-30 KV at max beam current. The high voltage must not, under any circumstances, exceed 33 KV. Each time a receiver requires servicing, the high voltage should be checked. It is important to use an accurate and reliable high voltage meter.
2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued X­RAY RADIATION protection, the replacement tube must be exactly the same type tube as specified in the parts list.
SAFETY PRECAUTION
Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or with the back board removed involves a shock hazard from the receiver. Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage equipment. Discharge the high potential of the picture tube before handling the tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts List. When replacing a high wattage resistor (metal oxide film resistor) in the circuit board, keep the resistor 10 mm away from circuit board. Keep wires away from high voltage or high temperature components. This receiver must operate under AC 220 - 240 volts, 50 Hz. NEVER connect to a DC supply or any other voltage or frequency.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this equipment have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements, electrical components having such features are identified by designated symbol on the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitutes replacement parts which do not have the same safety characteristics as specified in the parts list may create X-RAY Radiation.

4.1.4 FEATURES
Video / Audio Processing (AV-110/90 and Mono-110/90 concept) # Overview of available features (AV-110/90 and Mono-110 concept)
· Multi-standard vision IF circuit with alignment-free PLL demodulator
· Internal (switchable) time-constant for the IF-AGC circuit
· Switchable group delay correction and sound trap (with switchable centre frequency) for the
demodulated CVBS signal
CP-530 Service Manual
-20-
· Separate Second Sound IF output or FM demodulator output without de-emphasis available, which can be used as input for an external BTSC decoder or as input for external sound band-pass filter for second language processing.
· Separate SSIF input available as input for the FM-PLL demodulator to demodulate FM-radio with an IF frequency of 10.7 MHz, or as input from an external sound band-pass filter for second language processing.
· AM demodulator without extra reference circuit
· The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be
switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that the external band-pass filters can be omitted.
·The FM-PLL demodulator can be set to centre frequencies of 4.72/5.74 MHz so that a
second sound channel can be demodulated. In such an application it is necessary that an external bandpass filter is inserted.
· Audio switch circuit with 3 stereo inputs (1 stereo input can also be switched into two mono
sound inputs), a stereo output for SCART/CINCH with the possibility to serve as front/monitor audio output and a stereo output (with volume and tone-control), for audio power amplifiers.
The third stereo input is only available via the combined C2/C3/C4/AUDIOIN5R pin for the
right channel and via the combined CVBS4/Y4/AUDIOIN5L pin or INSSW3/AUDIOIN5L pin, for the left channel.
· Video switch with 3 external CVBS inputs. All CVBS inputs can be used as Y-input for Y/C signals. However, only 1 Y/C source can be selected because the circuit has 1 chroma input.
CVBS3/Y3 input available in combination with the G/Y-3 input pin.
·1 CVBS output, this output can be used as monitor video output or as front-end video output
or as independent selectable video output.
· Automatic Y/C signal detector.
· Integrated luminance delay line with adjustable delay time.
· Only one reference (24.576 MHz) crystal required for the m-Controller, Teletext- andthe color
decoder
· Multi-standard color decoder with automatic search system and various “forced mode
possibilities
·
Internal base-band delay line.
· Indication of the Signal-to-Noise ratio of the incoming CVBS signal
· Linear RGB/YPBPR input with fast insertion.
· Scan Velocity Modulation output. The SVM circuit is active for all the incoming CVBS,Y/C
and RGB/YPBPR signals. The SVM output is combined with the black current input of the black current stabilisation circuit. By means of a small application adaptation both functions can be operational in parallel. Picture improvement features with peaking (with switchable centre frequency, depeaking, variable positive/negative peak ratio, variable pre-/overshoot ratio and video dependent coring), dynamic skin tone control, gamma control and blue- and black stretching. All features are available for CVBS, Y/C and RGB/YPBPR signals
· The effect of the various features can de demonstrated by means of a ‘split screen mode in which the features are activated in one half of the picture and switched off in the other half
· Switchable DC transfer ratio for the luminance signal
· Tint control for external RGB/YPBPR signals
· Contrast reduction possibility during mixed-mode of OSD and Text signals. Option to make

a colored and in contrast reduced window.
· RGB control circuit with ‘Continuous Cathode Calibration, white point and black level off-set adjustment so that the color temperature of the dark and the light parts of the screen can be chosen independently. When this Continuous Cathode Calibration is not used, simple alignment of the cutoff level is possible.
· Adjustable wide blanking of the RGB outputs
· Horizontal synchronization with two control loops and alignment-free horizontal oscillator
· Vertical count-down circuit
· Vertical driver optimized for DC-coupled vertical output stages
· Horizontal and vertical geometry processing with horizontal parallelogram and bow
correction and horizontal and vertical zoom
· The IC can be used as front-end for Progressive Scan or LCD TV receivers.
· Low-power start-up of the horizontal drive circuit
