@miss_jessi that looks like an LED backlit display. Most likely it does not have a separate inverter. The circuitry will be part of your motherboard. Give us the exact model number for your replacement screen so we can verify this.
Check your connector. Make sure that it is properly seated and that it does not look like it burned. IF that checks out you may have to consider posting some really good pictures of your logic board etc., with your question. that way we can see what you see. Hopefully we will find out the make and model for your specific motherboard and that schematics are available.
