code printed on the board Supply 715G2545-3

pin voltage ON / OFF plate font always stays at 3.3V

has no swollen capacitors. I did not find the schematic diagram of the monitor. TL494 uses 16 pin output to excite the lamps.
TL494 can be defective? The on-off button already tested and is OK
At first did not display image on the monitor and also had a small leak in the high-voltage connector that went to the lamps, which was repaired soon after.

дефекта, расположенного: миниатюрные реле давления рядом с кнопкой питания, представленный сопротивление утечки. Я заменил ключи и блок вернулся к работе отлично
