Fix for RCA L46WD22 LCD TV without audio or having intermittent sound / audio

This is an old TV, but in my opinion well built one that will likely outlast great many of the TVs manufactured in recent years bare one silly defect in a fuse.

Hope this will save a good product from the dump and save someone a few hundred dollars:

Any 1A fuse will do the job, we just used a pico fuse we had handy.

I don't know where to ask a question so I'm posting it on the newest entry I can find.
I have a Toshiba 50HP66 Plasma that had the strobing problem and could see the input menu when I turned it on though it was in the wrong place.
I replaced the YSUS and am now getting multiple vertical bars shown here ( ).
Can the Y buffers cause that? I took them off and have shorts to ground across the pins of 3 ribbon connectors on one board and 4 on the other so suspect they are bad.
I'm just wondering if they are the cause of the bars or will I have to look for another problem.
