Hi YOGESH
Yes this is true . And as i told in comments repairing the tuner is also difficult due to lack of parts in the market .
thanks & regards

Beh!
These type of problem is common in "Satellite Receiver" & "DSL broadband" connection.Because service providers are using outside cable without "jelly filled". so that rain water can easily pass through the outer jacket of the cable up to the equipment.

In reply to beh.

...mentioned transistor is main transistor for amplification of all RF frequencies that are coming from LNB . and is most problematic
part in these kind of tuner. to find out that this transistor is good or bad first you to uncover the tuner and then turn on the TV
just by touching the transistor by your finger you will recognize that this transistor is hot or not if you feel transistor is getting hot for sure this transistor is gone and must be replace...

In reply to Dmitriy.

Dmitriy . yes specially when the LNB and receiver are near together the dish is outside of window and the receiver is inside the room and with a small length of cable are hooked together in this case water can penetrate to machine...........

In reply to Albert van Bemmelen.

Albert .most of chines satellite receivers are using same type tuners same model. 3.3 volts is coming from out side of tuner and goes to a 4 pod transistor SMD with code number T1J rarely you can find in the market of the world with working frequency 2 GIGA hertz but i found a substitution another one 3355 but with working frequency 1 gigs is better than nothing inside the tuner you will find 5 L the ohm value of each must be zero and 30 cap that you have to test them one by one to find the leaky one.. out side the circuit of course!.... if you can not see 3.3 volts inside the tuner you have to find out why?...
