I can give you some help on your TV. This is a plasma set so there won't be backlights. Capacitors in this set don't "blow up" unless they're over driven, but I doubt you have cap issues, a guess as to what made the pop sound was one of the transistors on the x-sus board, the one with the 2 large black heat sinks. Those are kind of known for giving issues and it's normal for them to short, and sometimes this causes a pop sound. Best way to fix it if you want to spend the money is replace both the x-sus and x-driver boards, a replacement sus board may fix it but a lot of times the issues starts with the driver, so a replacement sus can be damaged unless both boards are replaced, btw these boards won't be cheap, and they're hard to find, do NOT buy one from ebay,
www.shopjimmy.com is the best place to get boards however I doubt they will have them on a tv of this age. Also don't try replacing the bad field affect transistors, they will blow again.
