In this video, I restore an IBM 5155 Portable Computer from 1984 and do a white phosphor CRT tube swap. I disassemble the classic portable PC, replace the original tube, and troubleshoot the aftermath when multiple components release the magic smoke. Perfect for fans of vintage computers, retro IBM PCs, portable computers, CRT repair, phosphor tube swaps, early PC hardware, old-school electronics mishaps, and hands-on retro computing restoration adventures. - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics - Model F XT/AT restoration here: https://youtu.be/gIQ9idO1faU?si=_8q_WQrrPPjYZIxz 640k mod for IBM XTs here: https://youtu.be/Ixd39sOqTyc?si=L1n9e4xJvVIsN8-k Extensive CRT adjustment here: https://youtu.be/yDaaN2WgkWc?si=lVdaiPdsiHJ_UR0b - Tools I regularly use FNIRSI DWS-200 Solder station PinePower Bench PSU AMTECH NC-559-ASM Flux Kester 951 Flux pen Hanstar 861DW Rework Station Pro'sKit SS-331 Desoldering Station SEQURE HT140 Desoldering Tweezers Multicore 60/40. 0.38mm solder AOYUE int883 PCB Preheater RIGOL DHO800 70MHz four-channel digital Oscilloscope Tektronix 2246A 100 MHz four-channel analog Oscilloscope FNIRSI DPOX180H 180MHz Handheld Oscilloscope UNI-T UT61E Auto Ranging Multimeter UNI-T UT890D Manual Ranging Multimeter FNIRSI LC1020E LCR/ESR meter TL866 II Plus Programmer InfiRay P2 Pro Thermal Camera TOMLOV TM4K-AF Flex Microscope Dremel 3000 with flexible shaft MaAnt Mini"Dremel" DeoxIT D5 Contact Cleaner PCBs from PCBWay.com - Support me on patreon.com/Epictronics Buy me a coffee: https://ko-fi.com/epictronics
