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

1 Answer

Convergence Issues... Well - just about a year has gone by since replacing the ICs and the convergence has went out again on this tv. I never replaced the pico fuses because they weren't broken or discolored but wondering if that's why these latest ICs lasted only a year? Also, the pico fuses I received were a different color band then the one's installed so I was hesitant in replacing them anyways... HELP! See my original string dating back to July 2008; http://www.fixya.com/ThreadView.aspx?thid=778314&prdid=228313

    WHEN you replaced the chips did you apply heat sink grease (compound) to the new chips?

Hi I have a 52" RCA big screen tv that is only 3 years old however we turned it on today and it is showing some red blue and green lines and the picture is blurry


Hello clara7,

This denotes a convergence problem. I would suggest that first you enter the menu of your TV ad try to do an auto converge on your set, if this does not work I would suspect that the convergence ICs have gone bad and need to be replaced. I would suggest that you have a qualified TV repair technician replace the convergence ICs in this set.I hope this helps,Shuttle83http://www.electron-age-technologies-llc.com

Convergence problem


did you replace the six convergence resistors with the ICs? as Hitachi recommends replacing the six resistors when the ICs are replaced as the old ICs can harm the resistors and they will need replacement.

Is the power indicator flashing three times? If so the Ics have shorted shutting the set down. You will need two STK392-110 convergence ICs. You can get replacement ICs at the following link with free installation instructions.

Yes the Ics are easially replaced if you can solder. You will need two STK392-560 Convergence ICs and possibly the 12 4.7 ohm 1/2 watt resistors as Sony sets will usually weaken the 4.7 ohm. You can get the replacement ICs ad resistors at the following link and they provide free instalation instructions with picture as well as free online tech support in case you need additional help. Here is the link.
