I have a Lenovo ThinkPad Edge E545 laptop running Windows 10 that the screen no longer works on. A couple months ago the left hinge cracked (which I gather is a relatively common issue with Lenovo laptops), so I JB-Welded it back together and it worked fine until recently. Today the screen started to flash between black and a normal picture, before finally going completely black. I connected the laptop to my TV and the picture shows up perfectly on the TV, but the laptop is still black, so I’m pretty sure it’s a hardware issue and not software. My guess is that one of the cables going to the screen got damaged from the broken hinge. I’ve tried doing some research online for repair costs, but all I can find is for broken screens and screen replacements. Does anyone know what a ballpark figure for an issue like mine should be? I don’t want to attempt fixing it myself, so I’m debating between having it repaired, or if that’s too expensive considering the laptop isn't that new anymore and also has some keyboard issues, either getting a new laptop or a monitor. I’m a university student taking my classes online so not having a computer for an extended period of time isn’t an option for me. Thanks!
