I'm the bench tech at a casino. Working on a Tovis LTG-1750UR used in an IGT Game King upright machine. The screen had no backlight when it came in. So I carefully disassembled the LCD panel, took our the burned out CCFL's, and put in LED strips as I've done dozens of times on several other monitors. The ends of the CCFL's were burned black on the end and even severed in a couple places. Happens all the time in these old LCD's that run 24/7 for 5 years+
When I put it back together and powered it up, about the bottom 1/3 of the screen is black with a ghost image below the "unsupported" or "No Signal" message on the screen. I was very careful taking it apart and didn't crack or damage the LCD panel. However it was stuck down really tight to the frame so I had to carefully work a thin guitar pick all the way around the edge to get it loose so I could get to the back lights underneath, and it did take a little pressure to get it separated. I took it back apart once and reseated the LVDS cable on both ends and double checked for any cracks or damage. So before I throw it away, I'm looking for a 2nd opinion on if anything else besides the LCD panel itself could cause this, and if there's any way to fix it.
Thanks
