I had a no signal problem after replacing the lcd
I read up about it and how to fix it was to solder two tiny pins beside the antenna
I just joined them together and I got full signal
Ill find you a screen shot if you need one

You can test my solution with a bit of tinfoyle or a screw driver before you solder just join the two contacts together
