Boot tested power supply for the normal 135v, the power supply input line output transformer t402 is 2 feet with 135v voltage, and measurement of 1 terminal line output transformer t402 (horizontal output transistor collector) voltage fluctuation in 98-103v, touch line output tube fin has a temperature rise, the bank has startup work, doubt the line output transformer damage, with a newline after changing, the fault invariant, accidentally discovered the line output transformer 7 feet (the main channel with 12V voltage winding resistance (0.82) of r412 and ω /1w) end sealing off, re welding, troubleshootingqkEservice manual download site
