a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.

Hi,
If convergence out ICs got bad then it have to be replaced and yes, soldering work is required in circuit board to remove and install new ICs.
Required ICs STK392-110 for Panasonic PT-61HX40 are available in
Part Store for $15, TV needs two ICs.
Hope this info will help you.
Thanks.

If you turn on your set and you hear a clicking noise, or a ticking sound. You most likely have a shorted Horizontal Output Transistor (Refered to as a HOT)
I would recommend that you contact a local servicer in your area and see if they can come to your house and diagnose the problem and give you an esimate for the repair. This can be tricky to diagnose and the potential for electrical shock is very high. So I would be careful if you wish to repair it yourself.
I have done this repair before and I think that you should be able to get a servicer to your home and repair the set for somewhere between $350.00 - $450.00 depending on the parts that are needed and the area in which you live.
I hope that this helps you with this issue. If you have any further questions or, if you wish to repair it yourself please post back and I will try to help you as much as I can.
Thanks for using FixYa

Try re-soldering convergence IC pins first, they might get loose when you moved the TV.

First put a flatenned moving box to cover the screen and then put a blanket on the screen and then tape it up. This would help with the scratches. Get two long flat ropes than can slide under the tv (side to side) and the tie the ends together, get a helper and then both you and the helper put the ropes behind your neck while lifting and also supporting with your hands. This is how professional movers do it. Once its in a truck, put the flat side facing the truck wall and tie it up.

look at the convergance board it will be the one on the left there re two stk semi-conductors tward the back of the board. most likly one of them are bad but sometimes the soldering can be faulty. look for signs of cold solder if so just resolder and should be good if not also look for burnt resistors. it will be obvious finding the stk 's can be done by using google and just type in the stk # finding the resistors you might try calling panasonic to find the part #by telling them the location of the burnt resistor. good luck. mind you that the soldering of the stk (semi-conductors) you will want to use a heat sink on each terminal you solder otherwise you take a chance of burning the conductor befor you ever get to use it, if you have no exp. soldering i wouldnt sugest trying it !!!!

It's definitely not convergence. Sounds like more of a problem in the horizontal section.

You need to replace both STKs. They are pretty obvious to find in the unit. They are normally mounted to the same heat sink and will typically be about 3 inches long each, maybe 2 or so high...Front should read something like STK350-120

The power LED blinking ten times is indicative of issues with the voltages on Sub 5V, Main 3.3V, DTV 9V or the Tuner Power and the board in question is the "A-Board". Also, make sure that your units fan and airflow is not inhibited.
