I have a 50 inch plasma vizzo vp50hdtv10a. Its 5 years old and new had a problem until the other day. Went to turn it on and the screen had a plaid look to it so I turned it off and back on. When I turned it on the screen was blank but had sound and I could hear some crackling noise and smelt something burning (electrical).I couldn't find anything burnt on the boards so I figured it was a capacitor
Took it apart and replaced 10 capacitors and checked all the fuses restarted it and the same thing.

Should I look into it deeper or just junk it because I can but a similar tv...
