There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Reset will not cure a convergence problem.
this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).
If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.
Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.
No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.
If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

I had a similar problem with my 42 in Philips LCD HDTV. Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems. Here are some options for you. 1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?) Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk. 2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though. 3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourself it will save you hundreds. This may be your problem. If you determine that it might be. I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I
