Thats usually indicating the ICs have failed. Usually with that model its best to replace the board rather than try replacing the individual components as ther are several 3.9 ohm resistors that will need to be checked and possibly replaced along with both ICs. www.tvcircuitboards.com should have the replacement board for your model if you need one.

You have either bad convergence ICs or just bad grounds on the IC. I would go ahead and replace the ICs and check those small ohm resistors, as you have to pull the signal board out anyway. For futher instructions see the website www.TvRepairKits.com. They may have what you are looking for. Be sure you have the TV model number next to you. Thanks for asking and show a few hands of support!

Any shop with experience should be able to replace the convergence ICs which are the likely problem. This type of repair will cost less than the boaqrd replacment and won't require a conmplete reconvergence adjustment. The parts cost around $25-$40 each (there are 2).

I would look for someone that is able to change the ICs rather than the entire board.

I purchased the convergence chips for Samsung PCL5415RX/XAA TV. Do I need to remove the entire sub deflection board to R&R them?


Yes, however I would be surprised if changing the two Ics will repair the set, as that chassis should always have the sub-deflection board replaced since most of the resistors will be stressed. Thats why samsung changed the later chassis's by removing the convergence circuits from the deflection board as its almost 98% certain that the deflection board will need replacement when the ICs fail with those chassis designs unless every component in the convergence circuit is replaced which will cost more than the deflection boards do. But you may get lucky but if the ICs dont cure the problem you will need a new deflection board

3d convergence problem


Yes often the convergence anp is the culprit, But 9 out of 10 times its the convergence ICs themselves that go out. At 5.99 each its better to replace them first then if your amp is bad you will have the entire convergence system rebuilt. Where as if you replace the amp and its the convergence you could very well be out of alot of cash that really didnt need to be spent. I would change the ICs first thats alot cheaper.

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.
