Hoe do I replace the video cable?

how do I replace the inverter?

I'm not sure how to post the link from amazon. This is what I purchased...AMD Mobile Sempron Si-42 2.1ghz Cpu Processor Smsi42sam12gg Tested I did find out this weekend that it's not my video card causing the problem. But still not sure the problem. Since my HDD light does not come on, I had the hard drive tested & it works fine in another laptop. All connections seem fine, possibly motherboard problem. Also, the SD Card light does not come on when SD card inserted. Possibly motherboard problem. The dvd player runs, but not without a screen, I'm not sure if it is being recognized either. So without paying to have it tested, I'm at a standstill now. Guess it will go back into the closet until I figure something else out. HELP???
