Symphonic TV/VCR no power

[liammc00]

Got this symphonic TV/VCR and I don't know the model as sticker is missing but I judging by VCR mechanism it's from the 2000s. Soon as you plug it in Q601 (K2662)in the hot section starts making a high-pitched squeal. I did check the capacitors in power supply but they are tested in spec so it's not that. I also checked Q601 and tested fine. I don't know what else to do as switch mode power supplys are beyond unless it's a simple repair.
