Kp-46wt500 convergence problem

I have replaced the convergence chips, and all six pico fuses and I still get the tv flashing 5 times in standby and the heat sinks for the convergence chips feel cooled. Tv still has convergence issue but not as bad. Any ideas?

How to go in service mode for tv sony kp-46wt500.i did change the stk ic,the convergence is good in the midle but bad on the side


Did you replace the pico fuses on the G board there are two and usually one will blow when the old ICs fail and just replaceing the two ICs on the D board will usually not fix the issue untill the two pico fuses are checked and the blown one is replaced.

Kd-46wt500 sony big screen colors dont line up is projectors goin out picture on tv is blurry pic looks stretched out as well


Can you verify the model number and see if its A KP46WT500 model? If so chances are just the convergence Ics ( stk 392-560 ) and pico fuses are the problem. There are 6 3.5 amp pico fuses directly beneath the heat sink fins on the D board ( where the Convergence ICs are located) Check those six pico fuses and also two 5 amp picos on the G board ( where power cord plugs in) if any of the picos on either board are open then the Convergence ICs will require replacement.

Did you check the six 3.15 amp pico fuses on the D board in line with the resistors and the two 5 amp picos on the G board? Usually one or more of the Picos will blow especially on the G board

Check the fuses. If a convergence amp goes out, usually one or both fuses go as well.
I'd check the power resistors in the vicinity for opens as well.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
