Sony kp 51hw40 real projection tv


Below is exploded view of your Sony KP-51HW40 TV rear side which shows board names and location.
You need to check D Board for convergence ICs and these are marked as IC8001 & IC8002 on circuit board.

Jvc tv 56 convergence problem


on the 48WP30, you get to the convergence board through the front. Around the back edge of the speaker grille are four screws. You remove these screws. Then you remove the two other screws at the top of the speaker grille near the center panel underneath the front av input door.

THen after you get the speaker grille off, you take the four screws out of the wood panel door and take it off:

Those two big black heat sinks on the front there are your SK chips...on the convergence board of course. pop it up from those four tabs, and that will let you carefully move the convergence board so that you can reach in better, and unhook the three plugs on the right side (looking at it from the heat-sink side) behind the heatsinks (one for red, green, and blue each) and then on the other side of the board, you disconnect the other two plugs, but there's one that you actually have to trace back into the inside of the TV and unplug from a vertical standing board, since the socket is not on the convergence board itself. let me draw up a little graphic real quick.

Hope that helps.

If the board was "repaired" the settings should not have changed. There is a particular order to performing a convergence alignment. Do a web search for the service manual that will document the specific steps you need to take. Search using the model number and the keyword "manual". It should be availabel for $10-$15.
