Top Field Satellite Receiver Repair. Model TF6000EF

By on July 9, 2013

This Satellite receiver was brought to my shop by friend of mine that is also a repair technician. He said that he had worked on it but no luck. He could not find anything wrong with it. Well, the receiver is dead, something is wrong with it. From experience, this brand of satellite receivers is well known in the market for this kind of malfunction. Usually the problem is the capacitors in the secondary section of the power supply.

According to this guy, he said he checked the capacitors with a digital meter and could not find anything wrong with them. Well, I said let us open it and find out what is wrong with it.

I took the cover off and to my surprise; all the capacitors looked very new and power board was very clean. I found out later on that my friend cleaned this board with some cleaning solution.

I could read 300 volts on the main capacitor and the moment I checked the voltage at the secondary diodes of the power supply the reading there was not steady. I thought there was something with the secondary diodes but when checking with the Blue ring meter, it should me full light bars indicating, main capacitor, the MOS N FET and the diodes on the secondary section of the power supply are in good condition.

Just as expected, when checking the capacitors in the secondary section of the power supply with the ESR meter, I found that there are eight capacitors that gone bad. To my shock, my friend had no idea what is an ESR meter and I had to explain it to him.

There were three 1000UF, two 220UF, one 100uf, one 1UF, and one 33UF on that board that gone bad. The nice shinny capacitors on board do not mean they are in good working condition. They have to be checked to make sure they are working and that is why my friend did not check them simply they look nice and shinny.

We installed the power board back and powered it on, and the satellite receivers worked nicely. My friend was surprised and happy at the same time that it worked. He had learned a valuable lesson today, that he needed knowledge and the right tools to put that knowledge to work and make some income out of it.
