Common Malfunction of Television

Common Malfunction of Television Part # 1



Malfunction #1 :

Device is not working, No Power.

Description and location of the crashes:

It is clear from this crash the absence of sound, image and lighting device. Service is limited to electric power-Supply crashes.

Diagnosis and treatment:

- Set the device Alofumitr on a DC (direct current to measure).

- It is measured out the Department of standardization to the positive terminal of the smoothing capacitor (The large chemical-intensive).

- If there is an effort to unify the output (bridge) the Department of uniformity of sound, in the case of a continuing effort standardization within the 300-volt, this means a fault circuit standardization or dry chemical intensive private Baltenaim (300 volts) and make sure that Measure Service standardization and measurement of the Parties intensive chemical sector Baltenaim damaged them.

- In the case of a consolidation effort on the condenser is clear to us the great chemical safety and possible consolidation is a fault circuit voltage regulator, then measure the voltage feeding an integrated voltage regulator as well as measuring the various sectors of the electronic components from around the integrated voltage regulator and damaged them. Such as resistance to thermal damage or damage resistance carbon or a corrupted link capacitors.

- In the case of ensuring the safety of the sectors around the circle of an integrated voltage regulator is clear to us and there was a malfunction Palmtal the same, then change your mind is integrated with the technical specifications for it.

Malfunction #2 :

The device shows nor the signal is synthesized by any channel.

Description and location of the malfunction:

Clear to us in this malfunction inability of the device to call any channel, or search for frequencies for the various channels. This damage is limited between the integrated microprocessor and the Department of Automatic synthesis (tuner).

Diagnosis and treatment:

- Set the device to measure voltage Alofumitr continuous DC.

- Turn on the device to begin research in the process of synthesis.

- Place the negative terminal of the Alofumitr ground on the edge of the device and the positive terminal on the edge of (Tu)located on the legs tuner.

- Noted that there is a gradual change in voltage on the party (Tu), in the case of a change in voltage is clear to us the safety of an integrated microprocessor, to a change in voltage, which means that the existence of the frequency sent by the microprocessor to the tuner to allow passage of frequencies for the various channels.

- In the absence of a voltage change on the party (Tu) located on the tuner is clear to us and there was a malfunction Bmtal microprocessor.

- So, then measuring voltage of Bmtal microprocessor as well as measurement sectors from around the integrated and ensure safety before rushing to change the microprocessor and a change frequency signals on the party. (Tu)

Malfunction #3 :

Description and location of the malfunctions:

It is clear from the malfunctions was blue and it does not exist in the form of image color. It is clear to us from the restriction of the damage between transistors and integrated blue output colors. It is clear from this malfunction safety adapter output horizontal (Allain) as well as the safety of the screen.

Diagnosis and treatment:

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

- Measure the voltage signal blue on blue base transistor (B) socket on the screen.

- In the case of effort blue clear signal to us the possibility of corruption transistors out blue (B) or damage inside gun the blue screen itself and make sure that your measurement on a transistor Ohms and after making sure that safety measure the constant voltage feeding the transistor. To make sure your gun color measurement, priming color cannon to put Ohms.

- In the case of lack of effort blue color signal on the basis of the transistor,if it is clear there has to signal the beginning of the blue, the color came of the integrated three colors.

- Measure the electronic components which used in the binding process (such as damage resistance or a capacitor fixed link to link output signal of each color and the screen, or dry socket Sun condensate chemical) and non-damaged ones.

The same applies if there is any color of the three colors.
