I have a Samsung rear projection screen TV model HCL552W and the convergence will not line up When this first happened, I bought a new convergence modual and it did not help fix the problem Therefore, I bought new convergence chips and this did not help then I bought a new board and put it in And it is still not working the red crosshairs are tilted to the right is there anything anyone can Think of that might be the problem or does any one know were I can get a service manual or Is there a way to reset the convergence to the factory settings any help would be greatly appreciated
