Daksha..at first do not panic..and, yes the science of  Electronics is not a monopoly to anyone..anyone interested can follow Electronics and can do ample of things..for that we do not need to study the deepest theories..a person with a deep theory knowledge in Electronics never do practical stuffs..so, once again, do not worry..you can also do many things in Electronics..here you facing a simple problem..antenna of your Tx is broken..ok..

the most of the presntly available radio sets are produced in a same mother factory in China..in various brand names..these radios ranges from 4 to 9 channels..so, most of the components are same..here you can see the same transmission unit..
     At first, take your antenna module, so, you can see a gray wire, more clearly a shielded wire, with one core and one shield..slowly, remove the stiff plastic sheeth, from tip, to reveal the wires..wrap, the shielded wire gently, all along..strip a little plastic sheeth from inner wire..now we have two wires in hand, with antenna module..
now take your PCB in hand..and you can clearly see here , about the terminals as i marked..
for more clarity, i removed the antenna for you..its clear..

now, you can connect any broken link by soldering it..for that you do not need any SMD station..instead take a piece of copper, or brass wire, some thick, and clean its one tip with blade, or by art knife..

now you can solder it easily..and never forget to pull out the plug of the soldering iron from wall socket just before soldering..because a leakage current from your iron can damage some internal parts of the radio unit instantly..checkout all connections are sound after solder..take some extra care while soldering..patience is sucess..its all simple..

sir that is so kind of u to do so much work just to show me  Clap Clap  Hats Off Hats Off
but actually maybe my radio board can never be fixed because , a week ago , i had tried to solder , but by mistake i had dropped a drop of hot lead on that white chip (IC)  Bang Head Bang Head Bang Head ,so the lead was not coming out at all, and after seeing your guidelines i tried again , but the tx didnt bind with the rx at all   Cry Cry Cry
maybe my bad luck ,and sounds like i have to get a new radio.
Thanks for ur help sir Hats Off

Daksha..i wonder that, actually i do not know, why you disconnected the antenna from main board..any way, i hope you may damaged the transmission unit once..and most of such radios are in same coding and can try with all others..and i will try once that to get a transmitter board for you from Fly sky..i hold one now, but it is intended for my coming model project..so, once again, by using a lens, please trace all tracks, for any short circuits and openings..

Sir about a month ago both tx and rx were working fine, but 1 day i did a glide test for my plane, so on crash landing , the reciever went , but i thought the transmitter went , so went to rcgroups and noticed one guy saying that there may sometime be a problem due to the disconnection of the wire going from the main board to radio board, so i went , stripped my tx and cross checked the wires going from main board to rx board , no defects in the wires , as i was fiddling , the antenna wire snapped
 Bang Head  Bang Head , then somehow wrongly soldered it back on and bought another rx from vineet , when i got it that too didnt work , so then i created this thread Grin
