hello. after upgrading the xtrend 6000 with the openpeli 7 image all the decoder features working properly but the dvbs2 frequencies are either not taken or the images are frozen.does anyone know what the problem can be? thank you

What kind of reception do you have on those transponders?

What kind of reception do you have on those transponders?

I do not understand what you are saying !? The frequencies that are in the DVB-S2 mode, especially those with SYMBOL RATE of over 30,000, are heavily freezed and appear  on the screen of the TUNE Field, and the signal is jumping. One of the friends said that it's likely that there is a failure of the tuner capacitors or power supply capacitor failure. Is there a problem with the tuner or CPU device ?! I do not have such a problem on ordinary DVB-S frequencies.

I wouldn't be suprised that an old tuner like that can't even handle such high symbol rates.

 

And yes, it could very well be a power supply issue, a lot of old receivers suffer from that problem, and you do notice that in reception as the tuner uses the most power in the box, although I don't know if the ET6000 does. If you also have a disk in the box, even more strain is put on the power supply.

I had no problem with these frequencies before, so the problem with the tuner is not old. What I feel is that I'm using a receiver on a hard drive of 1 terabyte, is it possible that this causes this to happen and has a problem with the source of the battery? What's more, the problem that has just been raised when the receiver turns off the back button, it's not easy to turn on and should try again to turn it back on several times? Is this the same as the source capacitors?

[WanWizard]

Battery? You mean power supply?

 

Yes, is is most likely the culprit, bad capacitors make the power supply lose its ability to provide enough stable power. The biggest power users are the disk and the tuner. And when you switch it on, even more so as the disk needs to spin up, which requires additional power.

 

I even had a box once that rebooted when a recording started and the disk was in standby, because there wasn't enough power for the mainboard.

Yes, I mean the power supply. So this problem can be from the hard drive that has been connected to the receiver. Now all the power capacitors must be checked and the damaged capacitor should be replaced Thank you very much for help

This is the main board photo. I tried so much today but did not notice anything ?! What if the capacitance is damaged, which affects the images of the HD channels, which should be replaced?!? Unfortunately, I did not find anything to help and the problem remained strong. Two capacitors near the tuner have been replaced, but there is no change and the problem is still there.
1. Turn off the decoder from the back button and turn off the receiver and effortlessly attach the key until the receiver is turned on.
2. No signal on some DVB frequencies, especially those that have Symbol Ritt. Meanwhile, this problem has just happened, and I had no such problem before.
Please help anyone with this problem, given the picture I sent.

If the capacitors are not working the way they should, the power supply will have difficulty providing power at the correct voltage level, and will struggle to provide the required amperage under load.

 

Which is why the problem is first appearent with high power users like tuner and disk, and indeed, connecting a disk may change the situation from "just enough power" to "just not enough power". 

 

Ideally you need an electronics expert to have a look at it, with the correct measuring tools.

What is the film with capacitors measuring ohm that can not be seen? Did you see anything unusual? The device is on but it's not unusual! None of the capacitors can be seen as a flaw. It looks like all the capacitors are working properly. Is it possible to troubleshoot the device's tuner itself ?!

[WanWizard]

I am not an electronics specialist, so I can't help you with the details.

 

If it is a failing power supply, you can start by disconnecting the power of the harddisk. It will reduce the load on the power supply., see if that changes the behaviour of the tuner.

No voltage drop anywhere. As I do not have a hard drive in my featured movie. According to the expert who is testing the device, the device has no problems, but unfortunately the receiver still has a problem. I'm totally confused ?? It is likely that the wire that is connected to the LNB is in trouble! Even if it has been tested with another machine, and there is no problem!

Sorry I can't help you further, my technical knowledge is too limited.

A friend of mine had to replace some capacitors on the tuner of his Xtrend (it was a 9000).

Can you tell me which capacitors I have changed from the photo I took?!? The problem is, I do not know which capacitor is not functioning right now. The two capacitors of the tuner have been replaced, but there is no change. If it is possible to tell me with the capacitive image that I have to replace

Last night, I tested the device in a different location, and it turned out to be very low on the receiver, and the S2 frequencies were not even received at all. Is it possible for the tuner to be troubled? What can it be? Is the tuner to be repaired or should it be replaced ?! And is it now that the tuner of this device is on the market?

[Frenske]

I guess for what the et6x00 is worth you should wonder whether you’d better buy a new budget receiver.

 In my country satellite equipment is illegal, and because of this, all the receivers in the market are all Chinese and low quality, and on the other hand, this receiver has a lot of price (in the amount of two months' salary of a worker), which, if it is repaired, is much better than Buy a Chinese receiver and low quality, which has no function. The reason I want to repair this receiver is the same.

[Frenske]

In that case I can understand your point of view and hope you actually will be able to repair this box.

The capacitors are generally curved, you can saw it or feel it with your finger. Every capacitors which is curved or slightly curved must be replaced.
