Re: pic focus & convergence
Before you replace the ICs, try resoldering the connections on them. Also check the area for other poor solder connections. Resolder any that appear tobe grainy or have rings. Update this with your results and report if the symptoms change.

The tv have a problems known as a convergence picture problems it is dead.The tv have any colors lines like R,G,B mis alignments,tv have any colors shadows pictures or 3D pictures look alike?Yes,than the tv convergence board it is dead and the causes of these problems.The tv convergence board must have to repair like replacing like 2 STk covergence ICS and some or all of it resistors too.To fixed the tv convegence board to solved the tv convergence picture problems.The tvs shops will cost u like $300-350 for parts and labors.
Tv colors lines R,G,B mis alignment any way,the tv covergence board these parts are dead.The 2 STK convergence ICS and s ome or all it resistors are dead.The shop will,cost u $300-350 for parts and labors.
Tv have a problems known as a convergence problems,it dead.Any colors lines R,G,B mis alignment.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts must be replaced to solved the covergence problems.Try website like Tvrepairworld.com to buy a whole refurbish convergence board for the replacement.The Samsung/Akai tvs used the same convergence board.Or the shop will cost u $300-350 for parts and labors.
Ur tv now,totally have dead parts,on the tv convergence board.That,why ur flash foucus or manual covergence alignment R,G,B colors line will not matches up.The convergence board parts 2 STK convergence ICS and some or all it resistors,must be replaced to solved convergence problems.The shop will cost u $300-350 for parts and labors.
This tv have a problems call convergence,it dead.The tv convergence board must have the 2 STK convergence ICS and some or all it resistors are dead.These parts must change to solved covergence problems.The shop will cost u $300-350 for parts and labors.

If one of the colors (red, green or blue) is suddenly shifted, especially on one side of the screen, then one of your convergence IC's has burned out and needs to be replaced. A good rule when this happens is to replace both STK392-110 convergence output IC's with the updated and improved STK392-150's. This is by far the most common failure in those projection sets and is fairly easy to correct. If you do not have experience in replacing covergence IC's and realigning the convergence circuits then allow a qualified tech to handle it for you.
