Icom 7700 Front Panel Complete Restoration

Here is a slide show video clip detailing the complete disassembly of a Icom 7700 front panel. This front panel came off a donor parts rig that had suffered from smoke damage. This front panel and all the boards, ribbon cables, controls, switch assemblies were saturated with black smoke gunk. The internal metal cover plates and front panel chassis also had corrosion. After disassembly every was gently cleaned using 91% Isopropyl Alcohol and CRC QD Electronic cleaner and a ton of Q-Tip swabs. The knobs, front plastic bezel and all the plastic push button assemblies were washed, soaked and hand scrubbed with a toothbrush in the kitchen sink. There was a ton of black soot and crud all over the place. I was able to remove quite a bit of the corrosion using soap and a scotch brite scrubbing pad. The screws were soaked in WD40 to assist with rust and gunk removal. The memory battery was replaced CR2032. When removing the LCD display there is RF tape used on the top and bottom of the display. The tape is fixed to the metal sub chassis and can be gently removed and then reused. If you suffer from sluggish or stuck push buttons from years of dust or maybe liquid, this would be the plan of attack to clean the internal switch assemblies. Be well and stay safe, Len N2LEN
