Question about Panasonic PT-51HX42 51" Rear Projection Television
Your symptoms sounds like intermittent convergence IC.
There are two very large IC’s that control the convergence in this set. They are secured to a very large aluminum heat sink. They are on the left hand side of the set as you face the back on the signal board. The convergence IC’s will have a white number stamped on them that will be like STK392-110 or some kind of number like that.
What happens in the Panasonic set is that the convergence IC’s will short and cause the power supply to shut down from the overload of current. You will want to repair the set before this happens.
If you have a low wattage soldering iron, and you want to fix this yourself, let me know and I can help you with any questions that you may have. You may be able to rework the solder connections on the convergence IC’s and that will take care of the problem.
I hope this information allows you to resolve this issue.
