Question about Panasonic PT-47WXC43 47" Rear Projection Television

1 Answer

When powered up, no pix and power LED blinks three times

When I power it up, no picture appears and the LED blinks three times, waits for a time then three times (repeats this cycle). I removed the back and see some heat discoloring under one transformer and when I power up I hear what sounds like a relay shutting the sustem down?? Could there be a short and over current signalling to shut down?? I also smell heat related problems. Thanks for any help

    Thank you for the prompt response.

    I am not an electronics technician but have had some experience with electronics. If you can help me by pinpointing where the 145 volt measurement point is (and I assume this voltage would or should be present even after the unit shuts down, otherwise I will have to measure it within a 15 second timeframe), specifically which IC's are the convergence ICs and if the stk392-110 is an additional item or is the name of the convergence ICs?

    I would like to repair this myself as it is our personal TV and we are on a limited income so thanks for any guidance.

    I am having the same problem with my Panasonic PT-47WXC43. I did not notice any discoloring, but then again I don't really know what I'm looking for. Was this problem fixed? Any advice?

My Sony KDS-60A3000 randomly turns off, then the red "Power LED" blinks three times repeatedly (not "Lamp LED"). We turn it back on, the process repeats again between 20-60 minutes.


3 blinks of Standby/power LED of Sony sets denotes a SMPS board [G-board] failure. . Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

6) The TV’s lower left Blue Power LED will come ON.

8) Press the [Mute] button on the TV remote twice
9) Unplug the TV or remove AC power
10) Count to ten and plug the TV in

Shutdown & error led blinking 2 times


Shut off your projector by swith on the back near the AV inputs, leave it off for about five minutes. Then switch it back on, manually press the power button, let it start for about 5-10 seconds then continue to hold power button until picture appears. It worked for me, good luck to all.
