    The blue color and yellow seems to be shifting and showing a shadow outline and a soft fuzzy picture.



    An authorized Samsung repair serviceman stated that the blue color could not be aligned properly and may require a board replacement. He took my television to is shop with an estimated repair cost of $340.

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.

I need the outer screen for my Samsung HC-P4752W. Mine has a red line that seems burnt into it. Where can I get one?


It sounds like the RED CRT is cracked which will cause a red line. You can verify by looking into the lens of the Red CRT with a flasnlight if you see a line the CRT needs replacement. If no line then chances are the Convergence IC may have a problem.

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.

Samsung hc-p4252w - yellow tinge on left side of screen


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.

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

HC-P4752W - IC Replacement vs Convergence Module.


The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.

Samsung HC-P4752W Blurry ONLY on HD Channels


Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,
