Question about Panasonic PT-53WX53 53" Rear Projection HDTV-Ready Television
Three blinks is short protection----95% of the time in this set it means one of the two STK-392-110 convergence chips is shorted.
If you unplug the set and remove the back cover:
Look inside for the two chips: black in color--2 1/2 inches wide X 1 1/2 inches tall with the STK printed on them in white.
The will be on metal heat sinks with fins side by side.
What you are looking for is there are about 10 or 12 light blue resistors around them---most are marked 2.2 ohms---if you find even one of them discolored or somewhat white in the middle----YOU have found and confirmed your problem.
Parts cost if you can do it yourself is under 30 dollars--if you or someone you know can do it you can save the set and a lot of money--most shops get 300 or more for this type of repair.
I can also tell you the best place to buy the chips.
I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET; IF YOU WANT THEM I CAN POST THEM HERE.
Repair involves getting at the chips and being able to unsolder them--the instructions are my own and tell you everything you will need to do the repair.
