Cant adjust the convergence in menu colors look ghost,3d looking

You will need to replace the two convergence ICs and then check and possibly replace the pico fuses on the D board and G board. The Sony number one convergence repair kit available from is the correct kit for your model. The kit contains both ICs and the 8 pico fuses plus the CD with detailed repair instructions.

I have a similar problem as described as a convergence problem with my Sony KP-53HS30 TV. Can you elaborate further on the solution to repair. Which IC and protector fuses do I replace? Thank you.

Your model uses two STK392-560 Convergence ICs. also there are 6 pico fuses on the D board and two pico fuses on the G board which may need replacement also. The Sony type 1 convergence repair kit from contains the IC's pico fuses and a few resistors plus instructions on CD of how to do the repair.

That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.

My TV set, an 2004 Sony Model KP- WT510 Rear Projection is having problems with "Convergence" alignment; everything shows double or triple images and picture is totally distorted; I tried to align the...

The convergence output integrated circuits aren't doing their job. These are mounted on a heat sink on the circuit board, but they still get hot enough that sometimes the solder connections to them can break. Resoldering the connections would fix that problem.

It's also possible that the convergence circuit is not getting power, usually be due to failure of one of the outputs, which can cause protective fuses or resistors to blow. This would be harder to repair yourself because it involves determining what parts need to be replaced.

It would probably be worth getting a technician to look at the set and give an estimate for the repair.

If the IC your talking about has a designation number of IC601, the number is MX0841AB-F. Common regulator IC. Sony says that IC is no longer avaialable. You may get lucky and take out the entire G board and have, or repair the board for you. Good Luck

Oh no it is less expensive to repair the printed circuit boards. You should buy only the IC,s that sony recomends you to buy. They will cost you more then a replacement IC will but they are not all alike even if they have the same numbers on them. Go to and enter your model number and look for the STK IC. Don't forget to get some heatsink compound to install on the back of the new IC's before you reinstall them.. Remember to always double or triple check your work and make sure you have no solder bridges or shorts on the board. If you need a copy of the service manual, post your e-mail addy and I will send you one thru Pando. Pando is available online at for a free download. Pando lets you send large files via e-mail and the Sony manual is large. Good Luck
