No signal on sensation 4g

[jbthom4]

hey guys!
I have a bit of a puzzeler on my hands, hopefully you guys may be able to help me out!
I have the Htc sensation 4g from Vrigin canada
A few days ago i noticed that my signal strength was at 0, and i was unable to make any calls or surf the web.
So i go to virgin, and they set me up with a new sim (or three) to no avail.
I then call tech support, and they inform me that, simce my phone is over one year old, i cannot have the phone covered under the warrenty , no insurance me must fix the phone myself.
some information about the phone : I am s-off, running the latest radio (from here http://forum.xda-developers.com/showthread.php?t=1202867 ) on android revolutions's stock ics.

I believe i have tried everything, but maybe i missed something, here is what i have tried:
remove battery
factory reset
new sim
update radio
update ril
update firmware
lift connectors on back of phone to insure proper connection to back cover
try new back cover
remove old sim/sd reader replace with new sim/sd reader
return to stock rom

So that's that, what do you guys think? Do I have a bad radio transmitter/receiver? bad main board?
Every thing else on the phone works, even the wifi and fm radios.
I have noticed that occationally the phone will show a couple bars, but upon calling it says that i am not registered on the network. most of the time the phone reads no signal no network provider under settings->about phone->network

I really appreciate any insight that you may be able to offer!!
Thanks!

So your provider is not willing to help? If you are paying your provider monthly and your device isn't registering on there network I would give them a call. Simply state your device is no longer registering on there network and ask them what are they going to do about it? I would be furious if they refused to help me because device is out of warentee! Sounds like your kind of stuck . You have tried everything. Perhaps give your provider one more call and see if they can at the very least trouble shoot your device. Just because your device is out of warentee don't mean you still don't pay them monthly for service. By chance have you tried a new sim card? Just a thought....I do hope you get this issue solved soon. Best wishes

ok guys, I managed to get my phone signal back up and going once again, but it was no easy matter. for those who may happen along from Google or what not, here is the solution:
Buy a sensation with a busted screen, remove guts, place in your phone, re assemble, make phone calls again.

I initially just swapped out the main boards, thinking that the problem was with the antenna connections or something. I put my phone back together and still nothing. deflated.
I took the phone back apart and swapped in the flex cable, antenna connector cable, and the board at the top of the phone. after putting it all back together everything worked, I'm thinking that replacing the top portion of the main board was all that needed to be done; I replaced everything just to be safe.
so there you have it, i hope this helps anyone who stumbles upon this with a similar problem. my problem was a hardware problem.
