I have a TSOP v1.0 that I decided to make a first attempt at a RAM upgrade using a hot air rework station. After adding the fourth chip I began having FRAG errors. After several re-flows and checking all the pins, I figured I got bad RAM chips. So I removed them all. AND STILL FRAG…
after a closer inspection, I noticed that one of the nearby SMD capacitors went missing. C5B3. Any chance someone know the value of this cap, or has a list? I’m not sure if you can measure an onboard cap.
