Fix For Fried FrSky Receivers

[@alexk766]

Thank you for everything brother, wherever you might be.

[@McDeslandes]

I love your cheap fix videos. Totally my style! ✌🏼

[@Scrub_Zero]

Thanks so much for this bro! Saved my broke ass thirty smackers!

[@ProjectBlueFalcon]

I'm all about saving money lol

[@2d-reginaldomariakristinan330]

My goodness, Thanks from earth to heaven. I'm glad I didn't put my fried Rx's on the trashcan. Now I can use them still. RIP JC.

[@frankynathanael]

Wow nice and usefull info as I just fried my R9 Slim + last night and saving my $45

[@williamwellisch960]

I just joined that club. Put my picture on the wall of shame. Connected it to my X9D using the smart port servo wire without reversing the polarity at the radio. (Back pins)

[@reidbtable]

Thank you sir!!!!! fixed 3 x4rsb. my hero.

[@ProjectBlueFalcon]

Sounds like a lot of money saved right there.

[@JuanTipay]

Can this be done for the XM PLUS receiver??

[@pranavpasupuleti8137]

Jc I don't if your name is spelled like that but you are a god and you saved me $35

[@christopherlee3045]

a god? Its a voltage regulator bro he didnt split the atom! lol

[@mohammedjaffer8522]

As a newbi..I find your Vids very useful and educational. Keep up the good work. GL and many thanks:)

[@gozillasin9934]

I find your awesome videos time to time. Thank you

[@lepequie]

great fix! tough i have a problem finding the vreg on a couple of xm+'s that just stopped working and no component seems to be fried. i tried to follow the v+ lines but i only succeeded finding ground points. any chance you know where should i input the 3.3v???

[@DavidToyotaHead13]

I have a fly sky x6b that smoked on me and I'm not sure if it's the regulator or not. The chip I know for sure is burnt. It's a 6 leg chip on the bottom of the board commonly covered partially by white paste/glue. Best guess is a switching regulator? Thanks in advance!

[@alexjr.samson4222]

Very informative sir! btw...what causes the regulator to broke? In my case, I just re-arranged my Power connections from UART 3 to UART2 (together with Smartport config) and it poofs within 2 minutes...

[@kalinkha]

Hey JC welcome back !!!

[@TheBarrettrussell]

great video! I have a fried xm+ but cannot find a schematic for it. anyway you know where the voltage regulator is? thanks

[@cristianjaimes9459]

Hi, my brand new receiver only flashes once when I power it up, so I cannot bind it with my transmitter ,do you know what the problem could be?

[@soudmamado3421]

Same problem have you found solution

[@Kiwin412]

Hey JC nice job, continue to do great content that's awesome what you do ;) I've got a question: i accidentally pluged the 10V from the pdb in the 5V output of the vtx (not a FrSky, a cheap FT48X but still it could be 20€ saved), it flew 20s and snow and no more signal. Since then it does not turn on, no leds, do you think there any chance this fix could revive it ? Otherwise if you know what could the problem be and if it can be fixed ? (I don't need the 5V output maybe bypasing it if it the source of the problem) Thank you

[@SebitaLugano]

Es justo lo que buscaba! Excelente explicación, gracias!!

[@morpheusone7755]

Do I still power it from the same 5v pad on the fc

[@isabido]

Hello, I need to change the LDO since I use these receivers in fixed wing without FC. I can not find the reference! Could you indicate it?

[@minonim8749]

hey what could i do if i want to use it for PMW X4r ?

[@Detrock91]

Hi, I replace the Stm32 chip in xsr reciver beacuse my was damage (magic blue smoke, hehe :( )....is possible to get hex or bin file ?

[@tlcbuilders]

Have you heard of an xm+ going dead? It worked this morning and by the time I was done in Betaflight, it doesn't and gets extremely hot to the touch.

[@xawerymeloman3254]

Thank you :-) My D4R-II is now working.

[@pranavpasupuleti8137]

Should I remove the voltage regulator on x4r-sb or just solder to the 3.3v without taking out the regulator

[@dimitrishatzis9055]

Would love if you could help me with an L9R receiver, guide me to find the fried regulator. It is a bit more complicated than a x4r. Thanks a lot

[@bigrussfpvhell0]

also where do you buy smd regulators?

[@edfpv1827]

Please help: I have a turnigy iA6C and have already soldered a wire to my 3.3v on the flightcontroller. However I am unable to finish the fix as I am unsure where the voltage regulator is on the turnigy iA6C, please help me locate the voltage regulator. Many Thanks

[@JB-bi5vt]

Could you use a BEC set to 3.5v for those without an FC?

[@silmelumenn]

Not sure if someone will read this, but does anyone know how to apply it to XM+? I'm not able to find voltage regulator on this one receiver.

[@sosquadcopter6634]

What happend to you? My xjb 145 was working ok, then I updated the OSD and after that, receiver is not powering the lights up and no connection at all. Cant believe this sht. I just got my mobius mini v2 , ready to make videos and now this happens…

[@maxol96]

@@sosquadcopter6634 I was trying to update firmware, on 2receivers it worked on another 2 they just stopped working. I think i might just break the connection somehow between XM+ and taranis.

[@sosquadcopter6634]

@@maxol96 I had to buy another receiver antena =(

[@vinstonmusngi5016]

please help us find a fix on fried k969 receivers

[@HIBAW]

Crazy. Sure enough my regulator is fried. I plugged the Rx into an unpowered board, which would normally power the RX. That board is 36v and supplies a 5v regulated output. In this case, I powered the Rx externally at 5.2v. This is because I had forgotten if I powered the Rx from that other board, or if I powered it externally. Either way, hooking up the signal,5v,gnd from one of the channels to the unpowered board, fried the 3.3v voltage regulator. Makes me sad. Thanks for the video, I couldn't find the regulator info (162t was printed on mine), but assumed it must be 3.3v. I'll replace it now that I've verified it's dead. With this failure scenario, I'm guessing if I ever DO power the Rx separately, then I'll only connect the gnd's and signals to other things, besides servo's or whatever the Rx is powering :/ I still think it's kinda weird. Cause depending, if I'm using a big bec, I'm going to be a little paranoid attempting to power everything from it with this Rx. This is what I get for working with a weird setup I guess :)

[@EricRobb]

How do you fry a receiver. Please help

[@bigrussfpvhell0]

Yea the receiver connects and binds but doesent have any signal coming out? you should fix cameras and all that stuff that a component blows out on. I have a cam that will work and I can see my name on top but it doesent have video. and also should do blown vtx. this would save me a lot of money. also blown escs is an option as well. you could do so much with that hot air rework piece

[@ProjectBlueFalcon]

I do have some video planned like that. Just waiting for the parts to come in. I get most my stuff off of ebay. A lot cheaper but it all comes from China so it takes forever. Placed an order two weeks ago and still waiting. I ordered what I think is the correct 3.3v regulator for these receivers but I want to test it out first before saying.

[@JasperTielen]

Big RussFpv anyone knows if JC ever made that video, I know the 3.3v fix works but I want to try the real fix. Only thing on the X4R-SB I can read is "16"

[@sienp9674]

Russ.. sadly .. JC has passed away in a motorcycle accident a few weeks ago

[@thorstenpannwitz2345]

Hi does anyone know whats the number of the regualtor for exchange?

[@kringtheking2657]

Where can i find the proper fix, how to change the regulator ?

[@bigrussfpvhell0]

Hey what if the receiver works but it doesent get signal it binds and everthing

[@ProjectBlueFalcon]

I havent seen that problem before. I'll look into it and if I find anything I'll make a video.

[@awesomefacts3377]

ya same here

[@adamf1765]

Hi, how do i check that it is the voltage regulator that is fried,

[@adamf1765]

also is it the same as the r9mm? its too small

[@slyestrada8]

Hi, i have a couple of xsr here and they still turn on, but loses rssi signal in about 1 meter. Antennas are good. any chance of fixing it? to save a couple of bucks.... :)

[@3rd_coast223]

im in the same boat with an X4R-SB. got it brand new and have signal drop out at about 100' away. obviously I replaced it and the new one is good but I still have the old one laying around and would love to be able to fix it. Tonight ill check and see if the regulator is actually putting out 3.3 volts. but otherwise don't know what else could be the issue Project Blue Falcon, have you come across a receiver with poor signal issue and have any suggestions?

[@rwdkai]

3rD_Coast FPV There is a firmware update for this problems on frsky site. Although my reciever died half way through flashing, unfortunately it isn't the 3.3v regulator.

[@hejacky11]

Saved my RX THANKKKKK YOU

[@petrosue50]

G'day Jc tried this fix on x4r voltage output drops to .4 maybe something else cooked as well any ideas I hit high voltage power lines 66000 volts

[@ProjectBlueFalcon]

Thats pretty funny, but I'm sorry to hear that. Yea I'm willing to bet something else, or multiple things are fried.

[@MarcAntoine01]

Holy shit I can't believe he passed away.

[@leonelgarza9960]

???

[@Fpvfixit]

Yes

[@dronealone5651]

Miss u buddy

[@vesselfpv8274]

Volt meter says 1.3 volts out of the voltage regulator. Wut
