You will have to go in the service mode. be careful as you could damage the tv if wrong settings are changed. with the tv off push on the remote display 5 vol+ power. now hit the 1 button until you see pje fdis on the upper left. now push the 9 button to enter convergence. you should now have a cursor on the screen. usr the 3 button to switch colors. use the directional pad on remote to move the cursor and the enter button in the center of dir pad to select or deselct a point in the screen. push muting and then enter to save convergence. now restart the tv and all done

Model kp-53xbr4ct made 1998. picture was good. sudden went to center of screen and bowed up and down from center. it hade sound. turned of, now no sound. stand by flashes 6 times. unplugged , plugged back...

the video color distortion with the bowing in the center is called a convergence failure. the 6 blinks indicate a power supply shutdown for high voltage protect. the 14 blinks is just the tv trying to turn back on. you may be having to problems with the convergence and the 6 blinks or it may be related because the convergence amps can cause shutdown if they are shorted. i suggest calling a serviceman per the possible tow different failures. good luck

Tried to use 2002 Sony TV as large monitor for webinar. Got the TV to accept signal but could never size the screen correctly. It only showed part of the computer image. Gave up on using it as large...

Symptom shows that it is convergence out chips failure that causing misaligned images on screen. Please replace convergence out chips in tv to get converge picture.
Question shows it is Sony KP-46WT500, if it is different model let me know please.
I can provide you more technical assistance if you wish to repair tv by yourself.

Dear Doctor,
Check pico fuses PS8001 to PS8006 on D board where you replaced both STKs.
Make sure +22 volt and -22 volts are being supplied from power supply (G board) to D board.

Problem with my colors on Sony KP-46wt510

Sounds like the convergence ICs are giving out its a fairly commom problem with all projection TVs. Your model uses two STK392-560 ICs but I would suggest getting a couple of the 4.7 ohm 1/2 watt convergence resistors as most times one or two of them are open as well.You can get new replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can do the repair yourself. Here's the link.
