Hello all
I have a new issue with my Starship Troopers.
A few switches are not working anymore. According to the schematic all switches in column with the GRN-GRY cable ( CN5 connector) are not working anymore.
I checked the continuity from the cable to the first switch. There is a connection so there is no connection problem. I check the connector CN5 on the CPU board. I checked all the connections on the board that leads to that connector. All seem good until I get to the chip U203. There is no continuity on a specific area on the chip. It looks very corroded at that area. There is no continuity between the chip and R241. That's also the column of switches that are not working anymore. I assume there is a problem with this chip. My first try would be to change the chip.
Anyone know where I could buy this chip other than ebay?
If not, I found this: https://www.ebay.co.uk/itm/MM74HCT273N-74HCT-CMOS-74HCT273-74273-FAIRCHILD-Semiconductor-/233276007943?var=0.
Would this be the correct chip?
Thanks in advance for your help.
