Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Red & Green ghosting on one side

It looks like I need the convergence IC's. I have red and green out of alignment on the left side of my TV (from the center all the way to the left edge) Would this mean one of my Convergence IC's went out? If tis is the problem should I replace both of them while I'm in there?
Thanks

    I think this is the same problem. My left side tv is burry with red, blue, green colors visions/lines and the other side double vision. I don't know the model number but it's a 51" Sony.

More than likely yes you've had an IC go out. I would replace both. It never hurts, and if one has gone out the other will eventually follow. IC's are cheap and who wants to do it twice. :)

SOURCE: convergence problem

One or both of the convergence IC's are bad and has blown one or both of the fuses. Pull off the front speaker grill and remove the cover, loosen 2 brass scews holding the aluminum frame work, lift it up and out. Inspect The convergence IC's and the soldered connections to the board, check the fuses on the board. Replace both IC's and the fuses.

Covergence out of alignment on 1/4 Vertical left side of screen


You need to manually adjust the alignment:
On remote, press Menu to get to the main menu
Then arrow down to "ADVANCED FEATURES"
Then press "enter"
Then Arrow down to "CONVERGENCE" and press "enter"
"Red Convergence" should be highlighted
Press "enter"
You now have Green, Red, and Blue overlapping crosses.
If Red is out of whack, use arrows to align
To toggle to blue (and back to red), press "VIDEO"
Then align blue cross
Once the crosses look aligned, and nice and white, press "AUDIO"
This will bring up the Advanced Convergence screen
This is a grid of the same overlapping colors
You have control over the Red and Blue
If Green is very out of whack, you'll need a repairman…
While the "target" is flashing, you can move it around the screen with the arrows
Place it over an intersection to adjust, then press "enter"
Now the "target" is steady (not flashing), and you can use the arrows move your color
When it's aligned, press "enter" again
Now "target is flashing, and you can go to the next square.
You cannot adjust every intersection.
Some areas need to be adjusted via the adjacent intersection
When you're happy with color you're working on,
Press "video" while target is flashing to change to the other color
Repeat the above (blue is much harder to see and adjust for me…)
When you're happy with the entire grid, start hitting "Menu"
Each press brings you back out one menu level, until you are out of them
Once you're used to the process, it should take no more than a minute or two.
