Thanks, more or less understandable Well, it seems to me that my nickel is torn off, most likely it seems to me minus.

the device seems to be disconnected, I check with a multimeter and these diodes are short-circuited by the ones marked in red and you are in the repair process if you tell me what could be some other malfunction?

I can not help with that. My days of repair are years ago when things were much bigger on the boards.

You may find diodes in other dead equipment you have and can use them to swap and test.

Now days repair is more expensive than buying a new one, so not much repair is done.
Covid-19 may change that, but for now good luck.

it turns out the device works only from 12 volts! it battery battery the circuit goes on when I turn on these diodes and checked they are normal integers they don’t call for a breakdown they don’t show So it’s not in them but some kind of short circuit occurs in the circuit board somewhere else something has broken that is unknown on the attack and a separate board is not for sale Yes, well motherboard I mean that?

It seems that the kirdyk battery also came! it is already discharged, it shows 3.5 Volts when I plug it in, the display starts blinking, I find another satfinder there it has a battery connected the battery this device starts WOT charging is still not clear charging is turned off incorrectly turns off red light turns on indicator she discharged battery how many volts should it show?

Most batteries have their voltage on them.

Well, it says on it let's say 7.8 in and when it is discharged, should it show 3.8 in?

That may be a problem as lithium ion batteries die if they are fully discharged.
You may need to get a new battery.

You said it works while connected to the charger.
It may be cheaper for you to use a 12v battery, one of those sealed lead acid things.
I had seen batteries the same as the finder on Aliexpress some time back. Cost may make it not worth while.

I took apart the battery! there are just two plates and one plate just doesn’t show anything, but that is, it’s dead, 2 plate shows 3.8v 1 plate refused, it seems like the battery can be thrown away, at the moment I use a 12v charger from the power supply, then I realized you can use the battery 12v even without a controller? but how to connect its place 12 v zaryochcheka? How long do batteries last?

The finder battery lasted me 4-5 hour when I used it for a camping TV.

One of those small lead acid batteries taped to the finder should last some time.

Just watch your costs as buying a 12v battery could be most of the cost of a new finder.

AliExpress has all kinds of batteries in China! but what kind of battery can you assume that I understood at 12 volts that it needs to be charged somehow too, but it’s not clear how to charge it, it’s just discharging the battery, but how can I charge it if the batteries are on sale so that they charge from 12 volts somehow?

Hello! why why when I found another 7.4 battery in the same way, I connect the battery and the charger is connected, my red indicator does not light up before my red indicator lights up now, it doesn’t light up but it doesn’t turn on without a red indicator, the lamp doesn’t light up, is it connected to the controller or something Is this LED flown?

The red LED for the battery charge is red for charging and green when fully charged.

It may be that the damage your finder has suffered is stopping the battery power from getting to the board correcty, while the charger power does get to the board.

Hello! the resistors that I was looking for, I found them there, it turns out to be the 98th, they go, well, as you can see from the photo that two tracks are torn off, 2 tracks go down, as I understand it! and through two resistors, the resistor R30 R29 just like that, through it everything goes through them! I do not have a native battery, I found another satfinder and it is also 7 .4 volts! when I plug it in, the device seems to start up and shows risks and the battery starts to lose capacity, the battery drops by almost two sticks, the battery you plug in does not charge! here one of the two either needs a battery exactly the same which is for this device, or I got something wrong there, well, in principle, if you look at the picture everything is correct, although I could be wrong.

Hello! When I bought this device I had a very strong output lnb very hot! And also the processor is very hot! Put the update yesterday last March! I finally have some frequencies that he doesn’t see, for example, the Yamal satellite 90E 11265n30000 doesn’t see these frequencies, he sees 12718, but with other satellites for example 85E it perfectly catches both the horizontal and vertical transponders 11720n 12640, at the output I checked the inv-18 14 volt comes! Well, what could be the matter, can you tell me incomprehensibly?

Those lower frequencies are on the low band and need the 22kHz to be "OFF".

It may be that the extra loads your unit now has is loading the power supply that feeds the 13 / 18V and that switch mode supply is now running at 22kHz and that 22kHz ripple is making the LNB switch only to the upper band.

The first V71 finders had this fault and Freesat fixed it.
It sounds like you still have a fault that is drawing current and dropping the battery voltage.

and in my device there is auto mode and it does not change it is 22 kg in any way! I do not use the battery from the charger, I use it so far to 12v, but the battery I ordered from China, it has not yet arrived, I am waiting for it to come! But when my battery refused to work! I used a 12 volt charger! and these transponders 11265n30000, so to speak, have been working for some time! or maybe it’s such that our sun is hot and the heat was strong and the device overheated, maybe there is such a reason that it’s all because it was too hot from the sun? and doesn’t miss some transponders? and as for the processor, it shouldn’t be so warm, it’s very hot at me just like it is overheating! the output of lnb is also heated, and if the mirage of cinema voltage comes 13/18 volts! it turns out very strange that the voltage is 13–18 volts and the transponders do not work horizontally, some of them take the 85E satellite, for example, starting with transponders 11720n28800 and 12640v30000 it turns out Obi paralysis work, all channels work it turns out it catches even 90E satellites Yamal for some reason I didn’t work horizontally, but only 12718v27550 works vertically.

When you select a LNB of 9750/10600, the 22kHz is set to auto as for the lower band (9750) the 22kHz is off and for the upper band (10600) the 22kHz is on. The unit does this automatically for you.

You can do this manually by setting the LNB to 9750 and "OFF" for the lower only and 10600 and "ON" for just the upper band.

What I am saying is that if your meter is faulty and is sending a 22kHz ripple due to power supply issues, you will only get the upper band.
If you have a tone type satellite finder, plug that in, you may see the 22kHz LEDs for on and off flashing.

My post on the early finder fault that Freesat fixed is here.

Good evening! Yes, but I understand you. I tried to set the head frequency to 9750 and set up the transponder 11265v30000! This is the Yamal 90 satellite! No, it doesn’t catch. I also left the head clean. 10600 also doesn’t catch the signal. Only one transponder works from this satellite. This is 12718v27500. Well, on the device I draw 52% quality! Well, no matter how it was before, let’s say with such a percentage I found the channels and now I turn on the search, he searches for his ending, he writes no channels were found, although the quality shows at 50 before I had a good performance with such quality and the channels should register in this device Now it’s not looking for channels and does not miss all frequencies! Well interesting intelsat 85 E skips all frequencies as well, horizontal and vertical, I start 126 40v30000, and 11720n28800! Well, the quality is over 70%; well, the device scans when searching And it can’t find the channels before it wasn’t like I apparently when the controller was out of order it stopped scanning channels if I’m not mistaken But I don’t remember exactly when it happened. Yes no, I scanned it a week ago and now it doesn’t scan even if the quality is there, now the train doesn’t search but can’t find the channels, what could it be connected with?

There may be more damage in your unit than showed with burnt chips.

I admire you in you effort to fix this unit, I would have given up long ago.

Good luck

how did he work for me a week ago! and I didn’t have such a thing and all frequencies were accepted, but now I don’t mean something broke there, you can’t tell. As I understand it, what could be the reason? and why did he stop exactly when the search you do doesn’t find channels But what wasn’t like that?

Hello! it turns out I have a 6-pin SMD microchip burned MiAQB I can’t find the details on it anywhere! Well, here's how it burned out. My voltage disappeared 18 / 13v. If you know, tell me the analogue for it. I will look for such a microcircuit in a search, I have not found analog microcircuits anywhere.

Hello! well, if that’s interesting, then it’s worth smd SAhhh, replaced it and everything works on the output of lnb 18/13! now everything about transponders works well, for example, I checked the degree of 85 and the whole vertical and horizontal; others also checked the 90e Yamal, also worked vertical horizontal laptop channel search did not check forgot something I think it should work! so the whole reason was in this MiAQB microcircuit that it was scratched there, it’s not true, it’s not that microcircuit, it actually has a microcircuit Sahh, this is a native microcircuit. #Aliexpress KZT 653.29 11%СКИДКА | 10 шт./лот SY7208ABC СОТ-23-6 SY7208 сот
