Yes the HC-P4252W and the HC-P4752W are both P59A chassis so they both use the two STK392-010 Convergence amp iCs that are located on the sub deflection board

I have a Samsung HC-P4752W and see yellow and bllue halos.


Have you tried to use the convergence function on the TV? If that has not fixed this issue then you have bad convergence IC chips. These chips are microprocessors that align the blue and red tubes with the green (which is stationary). This converges the three tubes to create the image that you see. Failure of these chips (usually from heat over time) is a common problem with projection  TVs. The chips are not very expensive; from $35-60 for the pair. Replacing them involves some tedious desoldering of the old ones and soldering in the new ones. If you have some experience with electronics and soldering it is not hard. Shops will charge $300 and up for this repair. If you want to do it your self post a comment bnack here and I can assist you further.

If you put magnet speaker ( Standard speaker) near the TV, first you must move that speaker away from your TV because this will cause your colour TV screen color scattered. Then switch off your TV for 5 hrs. then switch it ON again your problem will be solved if the degaussing coil working.

Samsung convergence yoke?


The convergence yoke is the item on the neck of the picture tube closest to the circuit board which plugs into the very end of the tube. You can get a service manual for your model at the following link that will identify all the parts as well as troubleshooting and part numbers.

Not sure of the part number most use STK392-110 or 120s . You will need to look at the ics in your set they will have the IC numbers stamped on them they will have STKxxx-xxx whatever that number is thats the sanyo part number for those ICs
