    Does the power light on the front of the set stay on and then blink? If so, count the blinks--it will be an error code that may tell what the actual problem is. sd tech

If you can not power on your set your symptom sounds like a damaged convergence IC.

You should be able to get a local service center to repair this at
your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and
heat sink compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old
heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center
circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews
Electronics in California, they will have the OEM components that you will need.
Their site is
http://www.andrewselectronics.com/welcome.aspx
And their
phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the
phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a
good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try
http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this
information allows you to resolve this issue.

PT-47WX53G. TV got moved. Unable to move blue


The convergence ICs have failed which is very common when the set has been moved as a wek IC wont allow the color to be moved. You can get the PT52WX53G convergence repair kit from www.tvrepairworld.com which is the correct one for your model. The kit contains the parts and the CD with repair instructions.

Panasonic PT-47WX53 does not turn on


Yes, I did try to use the power button on the TV itself. That did not work too. Yes, there is blinking red light too. I searched through several sights and found out that it is an issue with the IC 4511. I could not find a place to buy the chip.


By the way, our local TV dealer asked for $400 to fix this issue. I had already spent $400 on a different repair on this TV, 6 months ago.

Any suggestion/advice would be very helpful. Thank you again for your response.
