In this latest episode of The 8-Bit Manshed, the host presents the Commodore 1083S monitor. While this model may not be widely recognized, it closely resembles the 1084S, with the key distinction being that the 1083S was specifically designed for the French market to correctly display the SEAM standard on a PAL monitor. It shares the same input configuration as the 1084S.
The monitors in question were sold as non-functional, and this particular unit bears a sticker indicating it is out of service. The “THT” label refers to the flyback transformer, commonly known in France as the “THD,” a critical high-voltage component. Upon powering on the monitor, the switch engages, indicating some functionality. However, shortly afterward, the monitor emits a sound, and the screen flashes rapidly—though the camera may not capture this. The host notes hearing the sound but refrains from leaving the monitor powered on for too long.
The positive aspect is that the power button is operational, so it does not need to be replaced. Nevertheless, further investigation is required, and the host plans to open the monitor to diagnose the issue. There is no visible high voltage on the screen, suggesting that the flyback transformer may not be functioning properly. Additionally, the flashing LED could point to an issue with the power supply, potentially linked to instability in the mains voltage. The host suspects the power regulation system may be at fault, but a definitive diagnosis will only be possible once the monitor is disassembled for further inspection.
