jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
;
Wszystko w porządku.
Instrukcja czytelna i kompletna.
Dziękuję.
all right!
thank you.

Instrukcja bardzo czytelna. zawiera co potrzeba. Polecam
QT-V5E/QT-V5H
E Market Service QT-V5E/QT-V5H Audio Manual CHAPTER 6. OTHERS [1] Function table of IC
IC101 9HX06526160501: PLL (BU2616F) Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Terminal Name XOUT XIN CE DA CK DO SD IFIN P3 P0 P1 P2 AMIN FMIN VDD PD1 PD2 VSS Input/Output OUTPUT INPUT INPUT INPUT INPUT �� INPUT INPUT �� �� �� �� INPUT INPUT INPUT �� �� �� Setting in Reset Crystal oscillation Crystal oscillation Chip enable Serial data Clock signal Data out SD input IF input OUTPUT Function For generation of standard frequency and internal clock. Connected to 7.2 MHz crystal resonator. When CE is H, DA is synchronous with the rise of CK and read to the internal shift register. DA is then latched at the timing of the fall of CE. Also, output data is output from the CD terminal synchronous to the rise. Comes ON during IF frequency detection or SD detection. SD signal is input, Observed by DO terminal. Input is for IF frequency. Controlled on the basis of input.
AM input FM input Power supply Phase comparison output GROUND
Local input for AM. Local input for AM. Power supply, with 4.0 V to 6.0 V applied voltage. High level when value obtained by dividing local output is higher than standard frequency. Low level when value is lower. High impedance when value is same. GROUND
IC203 9HX06830480284: DC-DC Converter (IRU3048CS) Pin No. 1 2 3 4 5 Terminal Name GND FB2 COMP1 COMP2 VCH2 Function Ground pin. Inverting inputs to the error amplifiers. These pins work as feedback inputs for each channel, and are connected directly to the output of the switching regulator via a resistor divider to set the output voltages. Compensation pins for the error amplifiers. Compensation pins for the error amplifiers. Supply voltage for the high side output drivers. These are connected to voltages that must be at least 4 v higher than their bus voltages (assuming 5 v threshold MOSFET). A minimum of 1µF high frequency capacitor must be connected from these pins to PGng pin to provide peak drive current capability. Output driver for the high side power MOSFET. Connect a diode, such as BAT54 or 1N4148, from these pins to ground for the application when the inductor current goes negative (Source/Sink), soft-start at no load and for the fast load transient from full load to no load. Output driver for the synchronous power MOSFET. This pin serves as the separate ground for MOSFET�s driver and should be connected to the system�s ground plane. Supply voltage for the internal blocks of the IC. Output driver for the synchronous power MOSFET. Output driver for the high side power MOSFET. Connect a diode, such as BAT54 or 1N4148, from these pins to ground for the application when the inductor current goes negative (Source/Sink), soft-start at no load and for the fast load transient from full load to no load. Supply voltage for the high side output drivers. These are connected to voltages that must be at least 4 v higher than their bus voltages (assuming 5 v threshold MOSFET). A minimum of 1µF high frequency capacitor must be connected from these pins to PGng pin to provide peak drive current capability. Driver signal for the LDO�s external transistor. LDO�s feedback pin, connected to a resistor divider to set the output voltage of LDO. Soft-Start pin. THE converter can be shutdown by pulling this pin below 0.5 v. Inverting inputs to the error amplifiers. These pins work as feedback inputs for each channel, and are connected directly to the output of the switching regulator via a resistor divider to set the output voltages.
