On that models its usually the pico fuse that are in line with the resistors that go, they tend to protect the resistors by blowing first. The picos are 3.5 amp

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.

Convergence


After replacing the stks you need to perform convergence adjusment procedure.
If Stk keeps burning out then replace convergence board.

no need to search and order multiple parts from different sources and pay multiple shipping fees!

Kp46wt500 covergence problem


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.

I have a convergence problem.


did you check the power to the IC's ... normally when either one of the IC's burn out it takes out the power supply ..... make sure there is both a positive and a negative supply present there ... possibly + and - 28 volts or so .... if any of the voltages are missing ,check the 5 amp fuses that look like little green resistors on the power supply board ... that should solve your problem ....

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

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.
