Question about Sanyo DS20930 20" TV
Negative image is due to the absence of Luminance signal in picture. You are now seeing only the chrominace part of it. It will be surely due to the Chroma Luminance Juncle Ic fault. You just open your TV, find the chroma luminance jungle Ic, resolder it out from the board, go for a same type and number. Replacing it wil resolve your problem. You must have good concept of soldering and desoldering, as this is a quiet complex job, which may need as far as 68 soldering points, very close to each other, and have the chance to get shorted between. Ok
