picture went off sound stayed on?

Hello,the problem you are describing appears to be a problem with the video processing board or a problem with the horizontal output.
I think best repair method is to replace both the flyback and the horizontal output transistor because if only one is replaced it is common for the other to fail soon thereafter.
If you need a tech I recommend you www.tvrepairjacksonvillefl.com but you should search the best and cheaper option.
