well it gets real compicated, if you are good with electronics and can take apart and put back together the inside the projector needs cleaned or the easy fix replace light engine about $600.00 rebuilt

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.

i have a panasonic pt47wx52 hdtv projection monitor . It will not power on and the red led light flases 3 times pause 3 times. What is my problem.

Your symptom sounds like a damaged convergence IC.
If this is the case the power LED should be blinking 3 times when trying to power the set up.
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.
If you need further assistance please comment to this post and I will try to help you further.
