You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window. Check the audio attenuation pin voltage.

One horizontal line on TV


Either bad solder connections on the vertical output IC or bad part in that circuit, IC or something else. I presume it is NOT a flat panel set but has a picture tube as no model number is listed.
