Tatung Company VS 14339 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Tatung Company VS 14339 Power Supply.

The Tatung VS 14339 is a compact industrial power‑supply unit used to feed the main board of older slot machines and similar control panels. Known failure modes for this model include an open high‑voltage resistor (R107, identical to R106 on Neotec supplies), which cuts all output voltage; other common issues are burnt capacitors or failed switching MOSFETs that can cause no power delivery. First‑check diagnostics: verify the input AC voltage and polarity at the supply terminals, test continuity of the high‑voltage resistor network (R107/R106) and inspect for burn marks on the board, then measure the output rails with a multimeter to confirm whether any regulated voltage is present before proceeding to component replacement.
