| First you have a 5" smaller set (50").
IKxx is the "location number" printed on the circuit board and used in the service literature. I'd replace ALL three as they ALL have the same hours of use, heat-cool, expansion-contraction cycles on them. Make sure company is reputable and are not selling cheap Chinese knock-offs ICs. Be sure to check any bias resistors for change in value. Also be sure receiving necessary b-pluses. |

|
| My T.V. is having some issues with the convergence(i.e.- Blue "shadow" along side the normal image). I have done some research and as far as I can tell the issue seems to lie within a burnt out IC. The model number of the t.v. is 50ux23k. The information that I have found seems to point to needing to replace this with the part stk4274 IK06. I know that the stk4274 is the chip itself but I am unsure about the IK06 part. From what I found there are 3 ic's, IK04/05/06, relating to the color. I have found the correct part online but am unsure as to whether or not the IK number matters or not. Any help on this subject would be greatly appreciated.
Thanks |
