Question about Sony KP-46WT510 46" Rear Projection HDTV

1 Answer

Component inputs don't work and convergence problems.

My set seems to have a convergence problem where the red is shifted over horizontally about 2-3 inches and is blurry in some areas. Also I get no picture at all when using the component inputs. All other inputs seem to work with convergence problems but I am unable to test the dvi input. From what I read I think I may need to replace the 2 STK IC's but could this also cause my input problem as well. Please help me.

    Well, I found out that the component cable I was using was bad. Hmm, still seems strange that the cable and the convergence ic went bad at the same time. Maybe a lightning strike or power surge could have caused this.

    Thanks T. I have already changed the two Stk392-560 ICs about 3 weeks ago with no problems since. I bought the ICs from MCM and they did not have Sanyo printed on them. I called to see about a return and the customer rep said that they buy them from Sanyo and they should be genuine. I didn't feel like waiting to return them and get new ones so I installed the ones I got. Hopefully they last a while for me.

Just a coincidence..........
Are you pursuing the convergence repair---Replace the two

I have sony tv kp-65wv600. It has problems. color and video is blurry, double vision, letters are curved


You have a convergence failure.

Convergence IC failure is very common. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless

Samsung Rear Projection Problem (not convergence)


The tv has 2 focus adjustments for each tube, mechanical and electrical.

1. Mechanical focus is set by looking at screen from back (through inspection plate on back of most samsungs) and rotating the lens assembly on CRT. loosen wing nut and turn lens assembly to go through focus and back to best position.

Put convergence pattern on screen and manually misadjust bottom red and green lines convergence so they can be seen through inspection hole.

With back cover of TV off you can usually reach your hand up beside the lens assembly to loosen the wing nut then rotate to adjust. Green is in the middle. The focus will be obvious when you rotate and look

When you are finished make sure the foam dust protector is not over any of the lens assemblies and the wing nut is tight.

2. Electrical focus - located at front of unit. the front grille/speaker cover is removed and maybe a cover over the front crt inspection hole.

In the inspection hole there is a black plastic "Focus/screen adjust Assembly" with 2 rows of 3 controls.

One row is focus and the other is screen. The middle controls are for green with R/B on either side. Usually the controls are labelled as "focus" and "screen". You want to adjust the focus controls, one for each color. Look for the focus or screen label imprinted in the plastic. Don't play with the screen settings.

With the same misadjusted convergence pattern you can see a red, blue and green line. Adjust green focus and watch green line for best focus. Do same for other 2.

Screen adjustments are very exact and delicate. The easiest way to deal with them is to turn color off in Customer adjust menu. Put any color tone adjustments in the middle (low, med, high, put at med).

You should have a b/w picture if there are no crt or other color related faults. If it is close to B/W leave screens alone.

If the pix is too green, then the green screen setting must be reduced a small amount. Do not play with these adjustments as most TV repairrers have a difficult time adjusting them.

If focus adjustments don't help then focus control or CRT may be defective. Needs expert to determine.

Blue out of whack around sides


I have the convergence problem with the red. After reading your site I replaced the 2 ICs and the problem is worse. Before the only problem was I could not adjust the red horizontal. Now I have no control over the vertical or horizontal and the overall picture is very red and it bows at the top and bottom very bad. A friend said I might have the ribbon connector in wrong or the convergence (silver box?) box maybe bad. Any ideas? Thanks,Dave.

Similar problem, then about 2 weeks later the SD convergence went out.
