This is a arcade machine LCD by wells Gardner, the model is WGF3299-SIAS03J, and the power board model is YIAPSA0041D.
See the circled transistor which has blown, it seems to have had the initials ZAA, other similar transistors on the board are inscribed ZAA J7.
Hello Refurb,
Searching for information on this transistor, it may be a KN3906S from Korea Electronics.
We do not carry this exact one, but should be a General Purpose transistor, 40V, 200mA, 250mW. A possible alternate is 4878-MMBT3906CT-ND.
Please check the datasheet.
