Try your lappy with an external monitor and let us know if the fault still happens. Be aware that when you hook up the external monitor you will probably have to make some sort of FN key stroke combination for the external monitor to work. That process can be found in your documentation.

I was finally able to get access to an external monitor today. The external monitor is fully functional with no display issues - the issue seems to be confined entirely to the laptop's built-in monitor.

Now it gets complicated. I need the complete model #, and if available, the serial #, of the lappy. There should be sticker on the bottom of the lappy giving model and/or serial numbers. I need these to attempt to locate a teardown of the laptop, because you'll be doing that if you wish to attempt this repair yourself.
So you'll know what we're looking at, there are 3 or 4 things that could be at fault;
1. The screen itself. They are usually around $70-$100 in price.
2. The inverter. A small part, not very expensive usually, but it's usually not the failed part. But it's in the signal path and must be considered.
3. The wiring harness. If it's crimped, bent or partially broken, it can cause odd problems.
4. The mainboard. Usually quite expensive, and very challenging to replace if you've never done it before.
A PC shop would charge $250-$400 to troubleshoot and repair this. You can do it cheaper, but it won't be fast. You'll be ordering one-part-at-a-time, changing it in the lappy, then seeing if it's fixed. If it turns out to be the mainboard, then you've ordered those other parts for nought.
So, your options are,
A. Fix it yourself. Cheaper in the long run and you'll get a wealth of experience tearing down a lappy, but it won't be fast.
B. Let a PC shop fix it, at the above mentioned estimate.
C. Apply any monies mentioned toward a new lappy, instead of trying to fix the old one.
Let us know.
