Common Malfunction of Television

Common Malfunction of Television Part # 2


Malfunction #4 :

The device has its audio and the screen is dark, although light the wick and the presence of high pressure.

Description and location of the malfunctions:

Service is limited to malfunctions out three colors (RGB) or a malfunction or lack of nutrition for the three transistors.

Diagnosis and treatment:

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

- Measure the voltage signals of the three colors on the rules of the three transistors (RGB). In the case of the absence of references to follow up the three colors in your circle integrated out colors and make sure the arrival of the voltage of Bmtal out colors, as well as follow-up to signal a difference within the three colors out of the integrated color in the case of an input signal voltage integrated and private sectors of the review must be integrated on the integrated linkage.

- Change integrated with a new one taking into account the technical specifications for it.

- In the case of signals of the three colors on the rules of the three colors on the rules of the three transistors Vicu malfunctions confined in the line of nutrition Linker for the three transistors.

- Follow-up the line of nutrition and make sure of the reason for cutting his effort Linker.


Malfunction #5 :

Image with vertical expansion is not enough.

Description and location of the malfunctions:

Shorten in the files of the deviation in a vertical or electronic components that link out integrated deviation of horizontal deviation of vertical files.

Diagnosis and treatment:

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

- Measure the output signal of deviation from the vertical output integrated vertical deviation and its conformity with the technical drawing of circuit device to ensure the safety and completeness of the out effort signal.

- In a state of output signal of the integrated signal then follow the progress until it reaches the vertical deviation to the files on the neck of the screen and measuring the link between the electronic components reference files and vertical deviation.

- In the case of safety components to link Check to make sure to adjust the key for the control of the individual vertical image.

- After confirming the safety of all the above is clear to us that the malfunctions have been limited in the files of the vertical deviation.

- Change files deviation on the neck of the entire screen.


Malfunction #6 :

There is no sound or sound is very weak.

Description and location of the malfunction:

It is clear from this malfunction and a picture on the screen with no voice of the channel visible. This is limited to the malfunctions in the Department of the audio output.

Diagnosis and treatment:

- Set the device to measure Alofumitr DC.

- Touch base the transistor when the raising key of one's voice and reduction in the maximum then observed that you make a dial tone or a click.

- In the case of a sound, check the sound department incentive effort by examining the integrated voice and nutrition examination sectors around him, and noted the damage resistance or damage to fixed or heavy damage during the process of intensive chemical linkage between the left and entered the audio signal.

- In the case of non-issuance of the sound signs while touching the base of transistor, the transistor Measure motivation and ensure safety.

- Measure the integrated out-audio and to ensure safety, in the case of damage to make sure the transistor or the integrated change the damaged ones taking into account the technical specification.
