I received a new main board. It was replaced and the radio works perfectly. The transplantation of display was not easy, because the soldered background leds, but it was solved . Thank you for your advice.

Thank you for your help.
I have not tasted the transmitter boards yet, but I suppose it was shipped by aviapost.
What do you think about replacing the main board? Can it solve the problem?
I hope the seller will send a new main board if it solves the problem.

It wasn`t modified. When I received it from china the battery was deeply discharged (original frsky Ni-Mh 7.2V 2000mAh). I suppose the transmitter was in the non working state during the all shipping time and it discharged the battery. (In non working state -when it doesn`t turn on - the transmitter...

I would like to ask somebody, who has a good taranis x9d plus se, to check R84 and R87 resistors (red squares on picture in my earlier post).

When I switch off the transmitter I know when it stays in working condition because then I can hear a click from the speaker after the screen stops. When the transmitter is switched off in working condition the speaker clicks randomly (quietly). I have measured the speaker voltage: it is 1.6V but wh...

I have checked components of magic switch. D1 D2 diodes are OK. R57 is 87kOhm R52,R55 are 10kOhm and R53,R54 are 70kOhm. I measured again the voltages on Q2 Q3 mosfets in working and nonworking conditions when the transmitter was turned off and on: Working condition transmitter was switched OFF: Mos...

The power switch (hardware) seems to be ok. That means this is a sad scenario. I found an answer of MikeB in thread "Taranis DEAD", where he suggested to check the main board components Q2, Q3 MOSFETs, D1, D2 diodes and R52-55 resistors. Are these components of magic switch or do you sugge...

Thank you for quick response. I have pushed on connectors and it didn't help. This problem is not a new coming problem but I decided not to bore you with all details. (But now I will) When I received the transmitter (it is a new one) the battery was deeply discharged. After I charged the battery I c...

Hello, please help me to solve my problem with my taranis X9d plus se transmitter. It does not turn on. I have to disconnect and reconnect battery to be able to turn it on. I have checked the voltage on pins of 8 pin connector of the main board. When the transmitter is switched off (after working, w...
