Purity and Convergence Procedure

Adjustment is necessary only if the CRT or the deflection yoke is replaced or if the setting was disturbed. The complete procedure consists of:

1.Vertical Raster Shift Adjustment. (Only for Models with Purity/Convergence Assembly with 4 Pairs of Rings).

2.Initial static convergence.

3.Setting the purity.

4.Final static convergence.

When the CRT or the Yoke is Replaced

Place the yoke on the CRT neck (do not tighten the clamp).

Place the vertical raster shift tabs at 3 o’clock (90o from the purity and convergence tabs)

Vertical Raster Shift Adjustment (Only for

Models with Purity/Convergence Assembly with 4 Pairs of Rings).

Apply a green pattern with a horizontal line, adjust the Deflection Yoke so that has no tilt, then secure it. Adjust center line of the pattern with the mechanical center of the CRT, this center is determined by two marks at the side edges of the screen. To adjust the line, once the vertical raster shift tabs are place at 3 o’clock to reduce its magnetic field effect (see Fig. 9 and Fig. 10) open the tabs the same angle from the center, until the center line of the pattern becomes a straight line, centered with the marks of the CRT. (see Fig. 11)

Turn the Receiver ON. Operate the Receiver for 60 minutes using the first Purity Check field (white screen) to stabilize the CRT.

Fully degauss the Receiver by using an external degaussing coil.

Slide the deflection yoke back and forth on the neck of the CRT until it produces a near white, uniform raster.

CT-32SX31E, CT-36SX31E, CT-32SX31CE, CT-32SX31UE, CT-36SX31CE specifications

The Panasonic CT-36SX31UE, CT-36SX31CE, CT-32SX31UE, CT-32SX31CE, and CT-36SX31E are part of Panasonic's renowned line of CRT (cathode-ray tube) televisions designed to deliver excellent picture quality and robust performance. These models are known for their advanced features, making them a popular choice for home entertainment enthusiasts.

One of the key features of these televisions is their large screen sizes, with the CT-36SX31 models boasting a striking 36-inch display. The CT-32SX31 models, while slightly smaller at 32 inches, offer an equally immersive viewing experience. The screens are designed with high-resolution capabilities that enhance color depth and clarity, allowing viewers to enjoy a lifelike picture.

Panasonic has incorporated various technologies into these models, such as the Digital Comb Filter, which significantly reduces image distortion and enhances the overall picture quality. This feature allows for clearer images with improved color accuracy, making it ideal for watching movies and sports. Additionally, the models are equipped with a 3D Y/C separation processing feature that further elevates the quality of video playback by enhancing the precision of image separation.

Audio quality is also a focal point of these models. The television sets come with built-in speakers, providing powerful sound output that complements the stunning visuals. With features like surround sound capability, viewers can enjoy an enriched audio experience that brings movies and shows to life.

Connectivity is another essential aspect of these televisions. They are equipped with multiple input options, including composite, S-Video, and component inputs. This variety allows users to connect various devices like DVD players, gaming consoles, and cable boxes, facilitating a versatile entertainment setup.

Durability and reliability are characteristic of Panasonic products, and these models are no exception. Built with quality materials, they are designed to last, ensuring that consumers receive value for their investment.

In summary, the Panasonic CT-36SX31UE, CT-36SX31CE, CT-32SX31UE, CT-32SX31CE, and CT-36SX31E are standout CRT televisions renowned for their large screens, high-resolution image quality, excellent sound output, and robust connectivity options. While CRT technology has since transitioned to flat-panel displays, these models remain a testament to Panasonic's commitment to quality and performance in home entertainment.
