Just put in a new PCB SUB because of convergence problem. Convegence is fixed, but a little blurry picture and colors are a little off.
Do I need to get a tech in for fine tuning adjustments? Or is there something I can do?

Re: HCL4715W Rear projection blurry
The focus controls on this set are in the front behind the bezel.
I'm not sure, but, I think on this age of Samsung, the screws to the front bezel are on the back side of the set. After removing the screws from the back, the front bezel snaps off and the door behind the bezel need to be removed. Watch the wires connected to the bezel, they need to be attached in order to turn on the set.
The focus controls are on a black control block (there are three of them, one for each color). Adjust each color for sharpest picture. I use words on the screen for alignment.
Each CRT board has a screen control (Adjust each slowly until retrace lines appear on the screen and then back off until they disappear). You may turn off the color and make sure that the picture is black and white. If it is not, then, which ever color is dominant, back it off a bit with that screen control.
Facing the set, Red is left, Green is middle and Blue is on the right.
Use only one hand inside an operating television. Do not touch the board, just the controls.
This concludes television alignment 101.

Tv have a problems known as a convergence pictures problems,it is dead.Tv have any colors lines R,G,B are mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv convergence board it is dead to caused these problems.The tv convegence board must have be repair like repalacing parts like 2 STK convergence ICS and some or all of it resistors too.To repair the tv convergence board to solved tv convegence picture problems.The tvs shops will cost u like $300-350 for parts and labors.
Ur tv convergence board that was replaced for ur tv.The 2 STK convergence ICS was old it is not new it is those 2 STK convergence ICS on the tv convegence board is dead again and some of the resistors on the board maybe shorted and dies also must replaced too.The tv convegence board was put on ur tv those parts on the convergence board are old components parts,ur must repair tv convergence board again to fixed this problems called convergence pictures problems.
Yes,this tv can be fix it have convergence problems.The convergence board the 2 STK covergence ICS are defective and some or all it resistors are dead.The shop will cost u $300-350 for parts and labors.
IF YOU HAVE DOUBLE IMAGES YOU CAN GO IN THE MENU AND TRY TO ADJUST THE CONVERGENCE, OR US THE AUTO JUST. ON SOME SETS IT IS ON THE FRONT. IF IT DOESN'T CORRECT THE PROBLEM THEN IT IS CONVERGENCE. I REPAIR 2-3 A WEEK. WE DO IT IN THE HOUSE, NO NEED TO TAKE THE SET OUT. MAKE SURE THEY REPLACE BOTH CHIP'S AND THAT THEY USE ORIGINAL PARTS, THE GENERICS DON'T HOLD UP. THEY USUALLY LAST 3-5 YEARS DEPENDING ON THE USAGE OF THE SET. DON..
