What does the light on the front of the TV set do. This is a self diagnostic tool. How many times does it blink?

Panasonic PT-47wx53 just shut off

Your convergence ICs have failed. Thats what causes the led to blink three times. The PT53WX53 convergence repair kit from www.tvrepairworld.com will usually repair that issue. The kit also contains the CD with detailed repair instructions.

Petty vauge possible Flyback/horizontal. since you don't get codes.. I would start with checking for +210 at D519, or look for high voltage.

Screen went black Panasonic TV/ PT-47WX53

Hello twisttolife,

What you have lost is horizontal deflection, this is caused by loss of the horizontal drive signal to the yoke transformers on the CRTs, for all three of these to fail at the same time is not likely so what I think is that the drive amplifier may have malfunctioned. To check this you will need:

1) schematic diagram or service manual (to determine the proper voltages and signals on the deflection board)
2) Multimeter (to measure the DC voltages on the components of the deflection board
3) Oscilloscope (to view the waveforms on the deflection board)

With these three pieces of test equipment you should be able to troubleshoot this problem.

Now if you do not have this equipment and what to take a chance at a blind guess, and just replace a board, I would suggest replacing the deflection board, this board usually contains the flyback transformer, the Convergence modules (which can cause this problem also), and the connections to the yoke transformers.

I hope this helps,

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.
