Re: Repairing Taranis Plus
With Mike's help, here is info when I upgraded a t9x to the M2561 chip: (viewtopic.php?f=95&t=3819&hilit=LM7805C ... 120#p74046).
With the flashing firmware er9x-2561 on this t9x.

Re: Repairing Taranis Plus
João, could not wait and did a first test.
And I have to say, it is AMAZING!
Used a scrap pcb, my colophony flux and my old LS-DIGI 60.
First the 4pin IC and then the larger one. Little bit of wood metal with lot of flux and the chip starts floating. And it keeps floating for some seconds!
Ordered from TMP-Löttechnik and there was a problem on their side.
Delivery took nearly 3 weeks, but I got 200g instead of my 100g ordered as an extra Enough for the next 100 years
And here is a video for demonstration -> https://www.youtube.com/watch?v=GwDZeEU34N8

Yes. But I am not planning to use it 24/7. Keep the room ventilated and wash my fingers afterwards.
Yes, I am soldering with leaded solder. Not healthy. I smoke and drink alcohol. Not healthy either.
Worked for nearly 40 years on ships, in power stations, steel- and paper mills.

Re: Repairing Taranis Plus
Hello
I have swapped the body and gimbals of my x9r plus, but after putting together everything no sign of life, not even on usb connect without battery does my computer detect anything. After reading a lot in this great forum I suspected cpu dead. Allthough I never plugged in or out the ribbon cable while the batterie was in. So far so bad. I ordered a new cpu and prepared myself to change it but while waiting I checked again.
Different to Andrew I have 0,46V at the side of R57 that connects to the cpu and 0,48V on the other. This does not change wether power switch is on or off. Another difference is no battery charge = no green led while using internal charger.
Could that mean my voltage controller may be foobared?
Now, I am very ashamed to admit: I cannot find it. While the non-plus board seems well described, i find about no pictures of the plus board with explanations.
Hoping for Light and Help,
Rolf

Re: Repairing Taranis Plus
Power from the USB connector (when operating in power off mode) goes through diode D6, so one side should be around 5V and the other side around 4.3 to 4.5V.
You should also then have the 3.3V supply (VCC) present. One side of R76 (part of the 3.3V regulator circuit) is VCC if you can't find VCC anywhere else.

Re: Repairing Taranis Plus
Ah, great, both Light and Help have appeared, thx Mike.
D6 voltages are 4.8 and 4.4
R76 is playing Hide and Seek together with his buddy, the 3.3V regulator. I cannot find them . The closest I get is R74 and R78 near the cable connecting main board and switch board. I am searching on the main board, right? Could you give me a rough hint where to find them?
Edit: I am measuring the voltages with minus connected to minus of the battery bay just in case that matters...
Edit2: Last night after more experiments I left the fully charged battery in the tx (switched off). This morning battery voltage is 2V. This does not feel good ...

Re: Repairing Taranis Plus
I got annoyed with myself for not finding R76 so I took the main board out again and detached all cables. Still nothing. Then I bend up the Elko (looks like it was added afterwards, different solder) and voila: Hide and Seek is finished, boys.
Reads 0.48V on one end, 0.12V on the other (measured against Minus of Battery Bay). No change if switch either on or off.
My Multimeter tells me the Ozilator is going at 18KHz but I wouldnt trust that since all the time while measuring the number is going up.
I looked up the pinout of the CPU to check where VDD is fed:
Pin 100: 0.467V
Pin 75: 0.461V
Pin 50: 0.459V
I am starting to hope. At least I am not surprised the CPU is not handshaking with my computer
Now found the voltage regulator (I think). No wonder I did not find it before, I was looking for a 3-legger. Looked up the pinout for TPS5401 and that's the point where my electronic noob skills end. Apart from Pin1 vIn I don't understand the output of that chip therefore I list the voltage readings of all pins:
P01: 4.8V
P02: 4.3V
P03: 3.6V
P04: 0.15V
P05: 0.35V
P06: 0V
P07: 0.1V
P08: 1.1V
P09: 0V
P10: 0.6V

Re: Repairing Taranis Plus
You are not getting 3.3V from the (switch mode) regulator. Either the regulator is bad or something is loading it down. Is anything getting warm/hot (like the processor)?
You say you have replaced the gimbals. Try unplugging the cables from the gimbals from the main board and see if it then works at all.

Re: Repairing Taranis Plus
Gimbals and Switches are unplugged - no change. All the time while testing I was scanning for smoke, bad smells and warmth/heat - nothing. Cool as a beer should be.
Connecting the battery again as >something< seems to suck it empty and measured amps:
Switch Off: 0mA
Switch On: 70mA
No heat. Maybe I did leave it on last night, that would explain dead battery

Re: Repairing Taranis Plus
Hello all,
still struggeling with my board. As there are no more tips I will change CPU in case that is pulling the voltage regulator down but somehow I dont put too much hope into that. So I am forcing myself to get friendly with the idea of getting a new board. They are available with and without display. Any Experience with that? Is it easy to change the existing display from the old to new board?

Re: Repairing Taranis Plus
CPU arrived:
First cut the legs of old CPU and then desoldered them. I killed a few conductor tracks, see what I can do about that:
Furthermore it looks like I lost C81. Anybody got the value for that?
Continuing to remove legs and clean up,
Rolf
PS Mike: Can I try measuring voltages of the voltage regulator now with CPU removed to see if something still is pulling it down or would that fail anyway?

Re: Repairing Taranis Plus
Bob, I have been admiring your soldering skills already. After cleaning yours looks so perfect. Did you apply solder to the tracks before putting the CPU on or is it better to start with as much of the old solder gone as possible?
