I would like to perform a electrostatic focus on my Sony Wega KV27FS12 set. How do I go about doing this? After taking the back of the tv off , then where do I procede. I read that the focus block is near where the front speaker grills are on the tv. I do have my manual, but it's not very discriptive as most manuals. Fristly it mentions that I should "discharge" the "anode" cap before removing it and proceeding further. Can I get someone here to give me a fairly discriptive procedure?
