Convergence issues thanks for the reply but my tv is a HC-P4252W not a HC-P4752W so my question is the parts and repair the same for both or is it different on my HC-P4252W ? Thanks

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.

Replace convergence ICs STKs will have part number on them STK392-110s,also (2) 2.7 ohm resistors open.

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.

Hi there,

I had a very simular problem and I managed to arrange it yesterday. Try and check the capacitors in the power supply. I found 2 capactors which I replaced and the picture improved alot. Also the convergence improved alot.

Give it a try.

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.

if youre having convergence issues with your samsung HC-P4752W you need to replace both convergence ICs numbers STK392-010 they are available at the following link and they provide free instalation instructions with pics so you can do the repair your self and they also give free tech support in case you need extra help. Its an easy repair takes about an hour from start to finish, Changing the convergence board wont help as the Convergence ICs are located on the sub deflection board and thats about 400 to replace the board compared to 50 to replace the ICs. Heres the link.

good luck
please mark the post with a fixya

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
