Question about Televison & Video
No need to go into panic mode. Since you work in an electronics repair shop- I'm sure they have repair manuals for LCDs. Review and apply the troubleshooting steps required to diagnose the problem you presented to this forum. In absence of any manuals, call the manufacturer's tech support hotline for repairmen or technician's- they'll guide you in repairing the problem. And certainly there is no shame in going to your boss and explaining your inability to fix the problem; after all you are still in training and no one would or should expect you to be ready to handle every problem that's put on your work bench.
This is all part of the learning curve- you'll gain the admiration and respect of your co-workers and boss for doing so. Don't try to bluff your way around it; who knows, this may also be a test of character and honesty.

I had this problem on a 37" Viewsonic LCD. Pulled it apart and through a process of elimination, I traced the problem back to a small board with several flat white ribbon cables coming out of it. The board was near the top center of the screen and under a ton of other equipment requiring almost a total disassembly.
This small board was clean but I noticed one of the rubber standoffs had slipped down and was making contact with one of the outputs running to the LCD. It also happened to be the output running to the section of the screen with the problem.
I postulated that the sticky glue on the rubber standoff may have just enough conductivity to cause a problem. Moved it so that it was no longer touching anything electrical and then reassembled the TV.
Afterwards, I turned it on and was pleased to see the problem has gone away! If you're having the vertical line problem, then maybe this could be your problem too, especially if you have a Viewsonic since it could be a manufacturing defect.
