[求助]東芝25E3XC3亮度失控

接手一臺東芝25E3XC3彩電,開(kāi)機蘭屏光柵過(guò)亮,無(wú)圖無(wú)聲,搜不到臺.換到AV,將亮度調到最小有圖像,但鬼臉,彩色不正常,將色彩調到最小,有黑白圖像但拖尾.懷疑亮度失控.測加速電壓207.5V(圖紙標180V),主電源電壓127.5V(圖標125V),測濾波電容C884(330U/160V),C447(22U/250V)正常.因第一次接手這樣的機子不知再從何處下手(電源無(wú)可調,圖紙的英文看不太明白).望老師指點(diǎn).現附上圖紙.

我這臺也一樣！滿(mǎn)屏的回掃線(xiàn)，懷疑高壓包壞！

剛查了是顯像管藍槍碰極了！慘！不知哪位高手能修？
