My guess would be 2.2 5watt looks to be coming off your bridge to the filter cap Did it get hooked up wrong or without a IT Isolation Transformer?

Maybe just overheated. Need to measure the ohms this manual maybe for your chassis. Check The zener in the power supply https://www.arcade-museum.com/manuals-monitors/Weiya 826HR schematic.pdf
