Tuner circuit.
GTV1000 design made such way, that UV1316 1336 (PLL) UV1315 (VST) used case tuner used, following measures have taken: Jumper J300 short circuit select right tuner address. Jumpers J301 J302have opened disconnect bandswitch lines. Resistors R3004 3007 have inserted connect bus. Resistor R3002 removed disconnect tuning voltage.
When tuner used, following measures have taken: Jumper J300 opened. Jumpers J301 J302 have closed connect bandswitch lines. Resistor R3004 R3007 have removed disconnect bus. Resistor R3015 removed disconnect 33V. Resistor R3002 present, feed tuning voltage tuner.

Resistor determine maximum voltage, which UV13XX tuner series. minimum voltage determined saturation voltage output TDA884X (0.3V). This minimum voltage important, because most tuners have fold-back lower part characteristic (1.1V UV13XX). correct resistor values GTV1000 indicated figure below.

TDA884X offers possibility insert OSD/Text into output. When fast blanking (pin pulled above outputs switched black level inserted. Because automatic black level loop, black level three colours different, depending upon picture tube. This means that inserted with fixed level, different colours present different picture tubes. other option insert directly into video amplifiers. Here reference voltage present, problem described above present. However most customers don't like this option, because extra wires towards board, which also increases problems. reasons mentioned above, GTV1000 insertion into analog inputs been selected. countries without SCART connections this problem from micro divided down correct level connected clamp capacitors inputs. countries with full SCART inputs, options available. First just adding SCART OSD/Text RGB, which course causes problem case SCART present simultaneously. second option using switch switch between SCART OSD/Text. GTV1000 discrete switch been selected, which little cheaper compared TDA8601 switch. problem however that application described below, expensive switching transistors have used obtain proper performance, which decreases price difference with solution. principle switch found Fig.9 external connector board passive clamp present input signal. compensate diode voltage clamp reference voltage made, using same diode clamp circuit. clamped signal connected switch resistor.

Reset supply-voltage-guard circuit.
This demo receiver sophisticated reset supply voltage guard circuit, which triggers micro controller reset EEPROM power supply. Most micro-controllers have internal power-supply guard which will generate internal reset once supply-voltage drops below threshold level. During this reset outputs have defined output condition (most time floating). However when supply falls further, even internal circuits micro stops functioning. This lead unpredictable bouncing outputs. Because I2C-bus controlled such outputs, burst pulses appear clock data-lines. This lead un-wanted write actions, because some EEPROMs keeps functioning very supply voltages. Once supply-voltage starts fall, external reset generated before internal reset becomes active (even supply falling glitch external reset will defined duration). same time EEPROM supply voltage switches-off.

Dynamic horizontal-phase correction.
Using supply horizontal deflection disadvantage. When displaying high intensity horizontal line required beam-current will discharge voltage. This energy will restored following horizontal flyback pulse(s), partly LLOT-primary from partly LHorizontal-Yoke from C9042. Consequently voltage C9042 will drop, next line-scan will start with phase shift right hand side screen. lines equilibrium will restored, hqqrq effect called "noses" will visible screen. reduce voltage drop across C9042. Without precaution horizontal phase-shift will visible after displaying horizontal white line cross-hatch pattern. energy needed white line delivered line output transformer (magnetic energy) during horizontal flyback. This energy will restored, partly from deflection supply (115V) partly from capacitor C9042. UC9042 will drop will deflection current beginning scan (left-hand side screen). This horizontal phase shift visible vertical lines cross-hatch pattern. Because LHorizontal-Yoke* dI/dT remains same, UC9042 increased most right-hand side screen giving more deflection current. This extra current causes phase-shift right. Now, average deflection current zero more, which indicates energy transfer picture tube. Sometimes takes more line-periods fully re-charge picture tube, take lines before phase shift disappeared completely.
