Yes just label any wires you disconnect then remove the screws holding the circuit board in (six screws) then remove the board very easy the hardest is getting the HV cable out of the splitter but it will come out with pliers twisting it 90 degrees put tape on the plkiers so you dont hurt the HV cable ( Large red wire)

How many convergence boards are on the sony model kp53hs30? and is there a step by step insturctions on how to change them? or how do you tell which one is bad? or just change both.

See attached photos of typical Sony---set uses two chips mounted to heat sinks with fins side by side.

This is a older set--chips will have number marked on front of them: STK-392-150, -110 OR -560.

The chips are usually located on the sweep board; you will have to get that board up to unsolder/replace them.

Depending on where you find them I can step thru the repair for you.

Total parts cost on EBAY for a pair of the chips etc will be under 25 dollars.

See also typical convergence chip--you need to id ones in your set for correct number.

If the information or photos helped you rate this solution as very helpful as I do this here for free.

If you need help,l am willing---have fixed hundreds of sets with this problem.






Chips will look like this but have different STK number on the front of them.


Typical Sony heat sinks with fins--chips will be mounted on other side.

Let me know if you have questions as I am here to help.
