Solve Most problems of Spark St7111 ( hardware )
From the experiences of others
Most and not all the problems of Spark st 7111 of congratulations and others because of the problems of hard ware result of the work of the device for a long period of the possibility of exposure to severe heat affect some of the condensates or the result of the accumulation of dust and dust on it and the solution, God willing
1. Check the capacitors that have some bulge and especially 220uf 470uf and change them
2. It is recommended in all cases to replace the capacitor 470uf 6.3v with the last 10v because it provides better performance of the device
This is done when technical maintenance because it has the experience and the possibilities for the decomposition and welding
See the next picture This is an intensive number and clearly visible
Intensive v10 -------> Replacement 470 uf 6.3v
3 - If the device is sound and there are no capacitors that have some bulge clean the device of dust and dust Balworo to blow the dust and then clean by kliner markets Kleiner to clean the devices There are two types of brown boxes for electrical devices, which have moving parts to clean and blue color of the equipment that does not have parts Which is to be used in cleaning the cans of blue color is large size and enough for many times enough to clean a little cleaning and then drying with Balworo or leave it 15 minutes will be Dries and it is not harmful to the Board of the revolution if not found a Balworo put it in front of the fan and It has to Dries and if you can not find a small brush (new comb) is not used to clear the dust
