I have a Panasonic PT-51HX41 after turning on the TV sometimes I have to do the convergence again.
Sometimes the Blue + wont move right or lift, the Blue will move up and down. The Red and Green work fine.
Another problem that may or may not be related is that the Power, Channel Select, Volume buttons on the front of the TV also doesn’t work.
The problem of your TV is in the convergence, there are two IC there that is cause the abnormality, you better reheat the feet of that IC maybe already crack or cold solder already,,the two IC there is a STK 392-110 or 150 ,if you reheated already and nothing happens ,you better change this two STK,so works better ,that STK is not so expensive..
Well i think it was on the tube is the problem
Try the hard reset method , that is, unplug all the cables and wait for half an hour , and replug all cables and try ......hope this will help you
