How do portable DC tv's deguass?
I picked up a Sony KV-8AD10 with really bad color and it almost looks like it needs to be de-gaussed. So i opened it up to check the circuit and there was no de-gauss coil or related circuitry. The set is supposed to take AC as well as 12V DC, but it has since been "modified" to accept DC only. So how do I de-gauss this thing other than manually--did old portable tv's not have this feature? Also could the color problem be related to the LA7650K IC? From previous posts on this group I've heard this suggested. Any thoughtful insights appreciated! Stu |
