Please help - sony kp57sw500 issue with convergence

Dear Respected Forum Members,

I converged my tv this evening in the full mode using the service mode (display, 5, Vol +, power).   First, streightened green lines (were not straight), then converged red over green; then blue over green.  Saved by pressing mute and enter.  Tried to copy on other modes by changing the value of ALCP to 1 in PJE menu.  When I pressed the mute and enter the TV showed all the letters very briefly in 3D patter - when it happened, the letter were like a bow.  However, the grid returned but the grid now ended up unconverged and had a bow tie effect i.e. like concave at top and bottom.  I had to restraighten the grid lines all over again in all modes.   It was a real effort to straighten the lines at the top and bottom of the screen.  Is my STK 392-560 failing?

 

Many thanks for your valuable input.

 

Regards.

 

Milton
