Replacing line driver power transistor on Sony TV
There's a fault on my Sony telly which I think I've narrowed down to the
line driver stage before the line output transistor. Certainly when I blast this transistor with freeze spray the set recovers, only to throw a wobbly again a few minutes later.(line width starts to become unstable/wavy on right, although all lines start OK on left, before the set closes down with 2 flashes on fault LED). I thought I'd try replacing this transistor, which is a 2SC2688. Does anybody know where I can get such a transistor in the UK, or how I can find an equivalent that will do? Thanks in anticipation, Alan Beamish |
