Common Malfunction of Television

Common Malfunction of Television Part # 6 :

Malfunction # 16 :

The presence of (jerk) is mixed with the image.

Description and location of the malfunctions:

This is clear to us in the malfunction and a (jerk) in any channel receivers, and this is limited malfunction between the adapter output horizontal.

Diagnosis and treatment:

- Set the key to this situation (Focus) Subject to the body of horizontal output transformer (Allain), with the observation of change or non-existence.

- In the event of a change in the picture is clear to us the safety of the focal length within the tube screen, and damage to the horizontal output transformer (Allain) which must be replaced it.

- In the absence of a change in the image, this means there are safety focal length (Focus) within the tube screen, so that the adapter output horizontal (Allain) is correct, and you must replace the tube screen itself with new ones.

Malfunction # 17 :

There is no channel on the receiving device and the presence of a black cloud on the Alrastr.

Description and location of the malfunctions:

It is clear not to receive any channel, nor is there any (numbness) on the photograph, but replaced by a black cloud on the Alrastr, and this is limited malfunction circle average frequency (IF).

Malfunction causes very high humidity to the device which leads to stopped working of the integrated work, and may result because of the non-device driver for a long time, or placed in locations prone to moisture and very low temperatures.

Diagnosis and treatment:

- The method of treatment to be put a tiny amount of gasoline because of its property on the Elimination of moisture.

Malfunction # 18 :

The device receives Channel 3, but can not receive Channel 4.

Description and location of the malfunction:

The presence of a single channel, and when you change the frequency can not receive other channels, is limited to the malfunction circuit synthesis and selection, any average frequency integrated IF and tuner.

Diagnosis and treatment:

- Set the device to measure Alofumitr an ongoing effort (DC).

- Connect the negative terminal of the device Ofumitr Bordi, put the positive terminal of the Ofumitr within the signal on the unit selection and synthesis (tuner box) is located on the edge of the IF tuner.

Noted a change in the mains voltage signal between the frequency receiving channel first and second .

- In the case of a change in voltage reference, this means the safety of the Department of selection and synthesis (tuner). And thus confined to holidays within the integrated average frequency IF.

- In the case of no change on the IF tuner edges of the channels it means that the safety of non-tuner and should be replaced by another, or to ensure the integrity of IF set out to adjust the average frequency of the first channel or second on a VHF frequency on high average and reset or change a new one.
