iPhone no service, cleam imei, correct date, good antenna, so how?

Hi I am a phone technician and I recently purchased a phone from a friend, iPhone 4s - unlocked.

I was able to use the phone on multiple network without a problem.

I changed the LCD, and attempted to use the phone a few days later but I was greeted with no service..

- Date and time is correct

- Antennas are fine

- Sim cards are fine

- all connections etc are fine.

- Clean IMEI checkmend clear

- Tried airplane mode toggle

- Tried battery

It searches for signal and then says no service, if I go to contacts my number is displayed at the top, I have had it on WIFI and iTunes, I have also updated to latest software, I also did a full reset and set up via iTunes and when it connected it said congratulations your phone is unlocked. No matter which sim card I try I get the same results.

I have tried everything I can think of, does anyone have any other suggestions please?

Sometimes (iPhone 5C has that problem more often) the time and the date is good but the year is 1970 and you can't adjust it right. Its motherboard problem, no solution.

To connect the time and date must be set correctly but otherwise it will be a logic board issue. there are several small components that if damaged will prevent connection. check all parts around the battery connector for continuity the smaller components are related to network connections.

But it seems to search for network though, I will have to take it to the specialist to take a look at the motherboard, thanks
