| Mar 13, 2023 at 9:57 | comment | added | JRE | The hint that it is a SMPS IC may not be enough to help you find a replacement - I took a quick look and couldn't find anything that matches. It might be easier to find out what voltage those two regulators were supposed to produce and replace them with separate modules. You'd remve the IC and probably other parts of the circuit, then wire in voltage regulator modules to the power input and output. | |
| Mar 13, 2023 at 9:54 | comment | added | Nandosuke | Is there any chance I could replace that? | |
| Mar 13, 2023 at 9:30 | comment | added | JRE | It is probably not a transistor. It is more likely a switch mode power supply integrated circuit. The large black things marked "4R7" are inductors (coils.) | |
