Damage That Often Occurs On The Television

Since I worked in electronics repair shop fix me a lot of television is broken. Actual damage is not so difficult to overcome. So this time I will explain the damage to television's most frequent and solutions address them.General damages on tv include:

1 There is sound but no picture 

For China's TV output is usually caused by a broken Playback. but for other TV brands can be caused destruction and loss of vertical IC socket solder the RGB, especially on the heater, it is usually worth the 5 volt AC.

2 There is a picture but no sound 

For cases like this a lot due to the destruction of the IC Audio. but there are also caused by the active circuit is muted [this is often the case, the solution is to stay off transistors only]

3. Voltage regulator which is not stable 

Thing we need to check is the circuit output. there is caused due to damage capacitors, simply replace it with a new capacitor, if still the same? try out lane at the foot of B + Playback. When the voltage becomes normal then it is likely Playback is faulty,, oh ya also be checked before its Horizontal Transistor

4. There is a line on the top of the image

This is like many I have encountered because of the destruction of 100uF capacitor, 220uf we just replace it with a new one, but in other cases such as samsung tv brands we just stayed on the menjumper Resistor voltage 50 volt

5. Colour Television all red

There is damage to the Video RGB, red section. transistors are usually broken ... in other cases it can also be damaged tubes, so before we check first its RGB output, simply remove the solder on the CRT socket legs on PCB, normally worth over 120 volts on each pin of his

6. Tight flashing indicator light 

No damage to the vertical section solderannya imperfect, just in re-solder it on the Vertical IC + Resistors are located close to the IC

7. Figure Vertical is not full 

Almost every TV output engine now there is damage to the capacitor 1000uf/35volt. There are also things like this is because damage to the capacitors on the IC image is usually worth 0.47 uF, 1uF, especially for Chinese TV brands no longer damage the 2.2 uF capacitor value

8. TV long life

Setabil usually because the regulator output voltage. for that we only have to replace the capacitors on the secondary circuit of his course. that is in use umamnya 100uf/160 volt capacitor, there is also wearing 220uf/160volt. should be replaced everything including the capacitor to the circuit control. Another case which resulted in a case like this is the destruction of the CRT socket

9. The television was on normal, but rather die alone 

Where IC regulators using STR 6753/6754 summer here many occasions when the IC is a direct drop but when it's cold sometimes like going anymore. Here we just replace them with new ones.

10. Figure Vertical lines are only 

To try to see this one at the foot solder Vertical IC may have a loose but when solderannya nice try at check incoming voltage, usually 24 volt diode atu may check its buffer when everything is normal can be sure the vertical IC faulty. so stay in replace it with a new IC must immediately guarantee normal again.

That's a few things that I can say. Maybe there are other symptoms, you can also add in the comments field. 

Hopefully USEFUL.
