No service after screen replacement?

No service after screen replacement?

I work in a repair shop. I just did a screen replacement on the s7 edge. After getting everything back together and turned on, there is a circle with a line through it where the signal bars are supposed to be. I did damage the coax cable and gave tried numerous other cables. I have taken it all apart multiple times and triple checked my work but to no prevail. Any help will be highly appreciated.

check the model number closely. a G935F charging/antenna flex will not work where a G935A was.

"I changed the battery on my GS7e, and after putting everything together, I no longer have signal. Sometimes it appears one bar 4G, but it doesn’t work. I then replaced the antenna but still it doesn’t work. what can I do?

I checked all the cables. Everything is where it belongs."

Adding my 2 cents, I figured my issue was the same, charging port daughter board. I had changed mine out in hopes to remedy a microphone issue. The board is for the correct model, north america version etc, but I found once I compared they have different revision numbers on them. Put the original back in and no issues, so not a cord or damage elsewhere. working on a galaxy s9
