DRV_RST SOS

The DRV RST circuit of the D board is used to monitor the physical connection of the D board to the C board. DRV RST input to IC9500 and IC9003 must be high for the unit to operate. The D board provides the 5V source needed to power the C boards. On the C2 board, the 5V is routed back to the D board via connector C20/C10, C11/D31 to activate the 5V SENSE circuit. A voltage divider consisting of R9369 and R9371 develops a voltage drop that causes the collector of transistor Q9301 to become low. As a result, the base voltage of Q9302 also becomes low causing its collector to go high. The output voltage is applied to IC9500 and IC9003 as DVR RST.

When the 5V SENSE circuit does not detect 5V from the C2 board, the DVR RST output becomes low. The unit goes into shutdown and the power LED blinks 12 times.

When troubleshooting 5 blinks SOS, isolating the C board and the panel may be necessary. To avoid having the power LED blink 12 times after disconnecting either D31/C11 or D32/C21, test point TP9010 should be shorted to ground.

Test Point TP9200 is the ideal location to check for DRV RST.

Generation Plasma Display Television specifications

The Panasonic Generation Plasma Display Television, a remarkable innovation in home entertainment technology, has set the standard for high-quality visual experience since its introduction. Renowned for their stunning display quality, these televisions employ advanced plasma technology to deliver vibrant colors, deep blacks, and exceptional contrast ratios. The screens are designed to produce lifelike images, available in various sizes, catering to both casual viewers and dedicated cinephiles.

One of the standout features of Panasonic’s plasma TVs is their superior color accuracy. With the ability to reproduce a wide color spectrum, these displays bring scenes to life, making colors appear more vivid and true to the original. The Real Black Drive technology enhances the display's ability to produce deeper blacks, resulting in richer image quality and an overall more immersive viewing experience, especially in dark environments.

In addition to impressive visuals, Panasonic also focuses on audio quality. Many models feature integrated sound systems that complement the stunning visuals, providing clear, balanced sound. For users looking for even more audio fidelity, the televisions are compatible with various external sound systems, enhancing the home theater experience.

The Panasonic Generation Plasma televisions are equipped with advanced connectivity options. HDMI ports, USB inputs, and built-in Wi-Fi functionality allow users to connect a wide range of devices, from gaming consoles to streaming set-top boxes, ensuring compatibility with modern technology. With smart TV capabilities, users can access streaming services, browse the internet, and enjoy a multitude of apps from the comfort of their couch.

Furthermore, energy efficiency is a key consideration in Panasonic’s design philosophy. Many models are built with energy-saving features that reduce power consumption without compromising performance, appealing to environmentally conscious consumers.

Durability and reliability are also notable characteristics of Panasonic plasma TVs. Designed for extended use, their robust screens are less prone to image retention, a common concern with plasma technology. With proper care, these televisions can deliver exceptional performance for years.

In summary, the Panasonic Generation Plasma Display Television exemplifies the pinnacle of plasma technology, offering superior imaging, impressive audio capabilities, extensive connectivity, and energy efficiency. This television series remains popular among consumers seeking a premium viewing experience. The fusion of these cutting-edge technologies ensures that every movie, show, or sporting event is enjoyed to its fullest potential, marking Panasonic as a leader in the realm of home entertainment technology.
