During a routine repair of the CCFL exchange, we encountered the following new issue on CIM’s when they are stored outside and are continuously exposed to the elements, especially heat and UV light (sun)
unit has 252 hours on hour meter,
CIM has date of Manufacture of May 2008
1. all cable ties are rock hard and are squeezing the wire insulation
2. the smd capacitor next to lcd connector has loose connectivity to the solder and PCB pads, causing either a blank screen with backlight on or the horizontal stabilization is lost due to intermittent contact.
The solder basically broke down over time and heat exposure of cubicle / CIM
this problem is mostly associated with lead free solder and no clean fluxes used for PCB assembly
3. The CCFL’s, which are basically fluorescent light bulbs, burn out prematurely.
The life expectancy for the original ccfl was 1,000 hours
