Sony KP -46WT510 Convergence Problem

Is it possible for a novice to replaced the IC's, Pico Fuses, etc that come with the TV Repair Kits which can be ordered online.

Is it difficult to get to the boards and do they need to be soldered; which could cause other problems on the board if done incorrectly? Can the entire boards be replaced instead? The cost?

Do you need the Sony Tech " codes " in order to do the manuel convergence after you make the repair. The projection TV is five years old.

Thank you for any help with this problem

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

KP-46WT510 Sony, locating boards?


I have the same model tv, with the same problem... convergence ICs were shot.  As you look into the back of the tv, the ICs are located on the backside of the large heat sinks on the tan board.  The pico fuses are directly under the heat sinks.  
Removing the board is fairly easy with the exception of removing the red cables at the rear left side of the board.  You have to exert a lot of force to pull them out (they go into the grey tower looking thing) but they do come out.  
I recommend taking pictures of the board before removing, and then make sure you label each connector you pull off the board.  There are six screws to remove as well.
Check with Sonny and Barry at this site.  They gave excellent directions and have a convergence repair kit for your model tv. http://servicemanuals.vstore.ca/index.php/cName/convergence-repair-kits

Good luck!
