• Transformer TR801 and fuse F801 fail repeatedly.
• No video, OSD OK, stuck in AV mode.
• One channel missing, probably NICAM.
• Standby warm.
• IF jungle.
• Takes time for picture to come on.
• Line pairing at top, linearity pulled out.
• BUZ in PSU fails immediately after start-up.
• Lines in picture. in the centre.
• No picture.
• No tuning. (KITON - CTV5125 information)
