How do I remove circuit boards from a plasma tv?

Can't quite understand your, "there are flattened power tapes connected in "

If soldered then remove solder and straighten with pliers.

If screwed or push on the simply remove

You will obviously have a soldering iron and multicore solder but Solder Wick will help greatly with unsoldering - you are very brave attempting this - are you sure the capacitors you wish to replace are actually on the board you wish to remove?

Good luck...
