Question about Panasonic PT-53WX53 53" Rear Projection HDTV-Ready Television
Here is what is causing your problem.
Three blinks is short protection and 98% of the time in this set it means one of the two STK-392-110 CHIPS used for convergence is shorted.
With the set UNPLUGGED, remove the back cover and locate the two chips mounted side by side on metal heat sinks with fins--they will have the full number printed on the front of them in white letters.
Take a good look at all the light blue resistors in front and around them--all the ones marked 2.2 need to be looked at to see if even one is white in the middle (discolored). They can all be tested just like checking a fuse.
Most shops are going to charge 300 or more for this kind of repair---BUT you can buy a pair of the chips on Ebay for less than 13 dollars plus shipping--I would upgrade them by using STK-392-150--same part but longer lasting.
Total parts cost should be under 30 dollars total. If you or someone you know can do it I HAVE STEP BY STEP, START TO FINISH INSTRUCTIONS FOR THIS REPAIR IN THIS SET.
They tell you everything you will need and how to do it--usually takes about a hour--longer if you are doing it the first time.
Let me know if you want the instructions and I can post them here for free.

could be power supply problem or high voltage problem. check caps in main power supply first.look for caps that have tops puffed up ususlly three or four.....

Make sure that lamp door is fixed securely and pressing lamp door switch as 3 times blinks shows lamp door switch is not On.
