When that happens, you unfortunately have to buy new drivers because at least one and often even several die in the process :( The Trigorilla mainboard can be revived relatively easily, because in 95% of the cases only the Zener diode (5.1V 1W Z-Diode). It has the identifier **733A** which also indicates the type. Here you can now buy SMD (surface mount device), such as the [SMAZ5V1-13-F](https://amzn.to/3aSzZN4), or you do it like me and buy a pack of 100 of the [1N4733 glass diodes](https://amzn.to/3jfuAT8), snap off the pins and simply solder them onto the board. The design is then not ideal, but they are easier to get and cheaper.;) When that happens, you unfortunately have to buy new drivers because at least one and often even several die in the process :( The Trigorilla mainboard can be revived relatively easily, because in 95% of the cases only the Zener diode (5.1V 1W Z-Diode).
