My oscilloscope display has a large dark patch covering most of the LCD like a large screen burn. It is just legible but difficult to use. Edges are OK. The backlight CCFL is OK. Also has squiggley yellow marks around the edge outside the active LCD area. Suspect the glass panes are delaminating.
Not found anyone else with this problem using Google.
Suspect that a new display is the only solution but not worth paying official price for it so has anyone found an OEM solution? Or have to buy a dead 123 on eBay and hope the screen is good. Or get a Smartscope which is half the price of a new display.
Not impressed by this unit's reliability as have already had to replace the battery, the keyboard foil, the battery current sense resistors and a 32kHz crystal early on in its life. Have not been able to get it running on batteries for years.
