Convergeance CRT?
Answer:
I have been in this industry for the past 9 years and to be honest you really don't want to open up the TV. I have seen my service manager cringe to his toes when someone brings in a set and tells us that they took the back off and tried to do this or that to fix it. It often ends up making the repair a LOT more expensive for the customer and turns what was an easy fix into a more difficult/complicated one.
TV techs can set the focus on crt sets etc but unless you have a rear projection tv with 3 tubes (red, blue, green) you won't have any convergence menus on your tv.
Most TV's have SERVICE codes that you can only get from the service schematics (usually can't get those unless you are authorized for repair by that manufacturer) to get into the service mode and unless you know what you are doing you can make a major mess out of your tv.
Please let an authorized tech look at your tv.
Neither. If you don't know what you are doing, don't bother opening up a TV. There's enough juice in a tube to kill you, even with it unplugged.
To add to the last poster, if your TV is a 2002 model, then the convergence can be done programmabley by using the remote. But, you need the service manual for the codes to access this data. Since you asked the question about which cover to remove, then I would not even make an attempt to try anything. Call a competent technician.
This is not a amateur job. Convergence problems are either caused by a bad CRT or faulty circuitry. Only multiple tube sets have convergence problems nowadays (either projectors or CRT rear projection sets). There can be tens of thousands of volts in potential that might kill you or hurt you very badly. Do not attempt repairs unless you know what you are doing (which you DON'T, having asked the question in the first place).
