V-Correction Adjustment (D02)

Preparation:

1.Apply a Crosshatch pattern.

2.Adjust (D01) so that V-Size is regular size.

3.If b-a<-1.5mm (in top and bottom), increase (D02)

by one step and adjust (D01) so that V-Size is regular; repeat steps until b-a≤1.5mm

4.If b-a>-1.5mm (in top and bottom), decrease (D02)

by one step and adjust (D01) so that V-Size is regular; repeat steps until b-a≤1.5mm.

MTS Circuit Adjustments

The MTS Circuit Adjustments require two steps:

1.Input Level Adjustment.

2.Stereo Separation Adjustment.

Input Level Adjustment (M00)

Preparation:

1.Connect an RMS meter with filter jig as shown in Fig. 37.

2.Connect an RF signal generator to the RF antenna input.

Procedure:

1.Apply the following signal from the RF signal generator:

Video: 100 IRE flat field, 30% modulation.

Audio: 300Hz, 100% modulation, monaural (70 ±5dB, 75Ω OPEN, P/S 10dB).

2.Adjust the MTS Input Level Adjustment (M0) until the voltage measured is 106 ± 6.0mV rms.

Stereo Separation Adjustment (M01 & M02)

Preparation:

1.Connect an RF signal generator to the RF antenna input.

2.Connect oscilloscope to TPE10.

Procedure:

1.Select Stereo Mode in Audio menu

2.Apply the following signal from the RF signal generator:

Video: 100 IRE flat field, 30% modulation.

Audio: 300Hz, 100% modulation, stereo (left only) (70 ±5dB, 75Ω OPEN, P/S 10dB).

3.Adjust the MTS Low-Level Separation Adjustment (M01) until the amplitude displayed on the scope is minimum.

4.Apply the following signal from the RF signal generator:

Video: 100 IRE flat field, 30% modulation.

Audio: 3KHz, 100% modulation, stereo (left only) (70 ±5dB, 75Ω OPEN, P/S 10dB).

5.Adjust the MTS High-Level Separation Adjustment (M02) until the amplitude displayed on the scope is minimum.

6.Repeat above steps 2 through 5 until the amplitude is minimum for both signals.

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.
