Produced by the Minsk Radio Plant , these TVs transitioned the brand from older Soviet-style discrete component designs to modern, integrated "monochip" architectures. While the CRT technology has since been replaced by LED and OLED models from the same manufacturer, the 670 chassis remains a point of study for hobbyists interested in analog video engineering.
Managed by the TDA8356 (vertical) and BU4506DF (horizontal output transistor), which control the electron beam's movement across the screen. Repair and Reliability shemy televizorov gorizont 670
For technicians, the 670 series is notable for its accessibility. Schematic diagrams and service manuals are widely available in archives like RadioRadar and Espec . Common maintenance tasks for these units often involve replacing aging capacitors in the power supply or vertical scanning circuits, a standard procedure for maintaining CRT lifespan. Historical Context Produced by the Minsk Radio Plant , these
The , specifically models like the and , represents a significant era for the Belarusian electronics giant, Horizont . Built on the ShTsT-670M (ШЦТ-670М) chassis, these television sets were staple CRT (cathode-ray tube) devices in Eastern Europe during the late 1990s and early 2000s. Technical Architecture Repair and Reliability For technicians, the 670 series
Often uses the UC3842AN integrated circuit, a current-mode PWM controller designed for efficient switching power supplies.
The circuit design of the 670 series is characterized by its modular yet integrated approach, utilizing a specific "component set" common for its time:
