I think you can probably see from the tenor of the responses you have seen here that the consensus is the concept does not work.
I think the reason here is twofold:
1. The design is overly complex, and one of the issues is that the name is actually very difficult to read and discern. You dont want your logo to require deciphering. It should be immediately apparent what it says.
2. I think the t-rex image here is difficult because there is no link between a dinosaur and the concept of computer repair. It looks like its all about the dinosaur, which I think is what is raising eyebrows. Perhaps the better path would be some degree of subtlety? In other words, maybe your logo concept would work better with the immediate impression being the name, and then if the reader looks a bit more closely, a reference to t-rex. (An "oh yeah... thats what that is" moment). Its in there, but it doesnt overpower the whole image.
At the moment it looks like its all about the dinosaur, and I think thats why its being received negatively.
Hope this helps. Just my 5c
