IBM PC Server 500

Just what I needed to send in my findings today while working for consumer depot service for my work experience (that's the shop name), Boss and I talked about what he have seen from college's churning out students filled with knowledge but very little troubleshooting skills *especially* at component level and wrong type of skills to boot! The area students trained with were for peecee area. 1. Newish monitor sent in w/ complaint sheet stating dead. Powers up fine huh? Now on testing....to see if owner might be wrong. 2. Service manual for samsung 76V under warrenty flowsheet says if no PSU voltages present check & replace bunch of transistors and expensive ICs, still not fixed, replace whole board. (!!) That problem vexed me bec paper doesn't agree w/ what I find then turned out that poly 100nf capacitor was shorted far down the power chain (on CRT board) 70V rail for that intergrated tube gun amps in T220 9pin package. PSU was very touchy to current level that how were no burn marks. I don't like shot-gun swapping chips idea. DMM and CRT board unplugged from mainboard gave short truth away. Did all tracking right on the board itself without schematic. I find using the schematic didn't do good for me and usually slows me down. 3. 12 years old TV playing but soundlessly. 36V for audio has track break, leapfrogged across length of that track w/ dmm till I found the break (right at one solder pad crack is invisible). But didn't brother being dainty w/ it, quickly patched in one piece of long patch wire, making 3 connections with minimum amount of wire since I don't like loops. Got sound in minutes. Oh yeah, blackened crumbly glue scraped off. 4. Newish monitor under warrenty, CRT socket partly plugged in from factory, Samsung uses crt board unit clamp w/ silicone grommet around CRT neck, very nice idea but that gromment was stuck against edge of thick flame-proof tape. Worked crt thing over that tape's edge and clamped down, now fixed. Cheers, Wizard
