Question about Panasonic PT-53WX42 53" Rear Projection Television

1 Answer

Panasonic PT-53WX42 - When I turn the TV on, the red light comes on but, no sound or picture.

My TV is 5 years old and stopped working. Someone is telling us that it is the lamps that burnt and needs to be repalced. Our TV has 3 lamps, do all three have to be replaced? I was reading one of the solutions to a simulair problem and it was saying that the Convergence ic's need to be replaced. Can you please tell me the correct answer. When you turn the TV on the red light in the front is on, but no sound or picture.

    Thank you so much for getting back to me. I really appreciate it. The light in the front is blinking, however, i am not sure how many times. I will check it tonight when i go home. If it is blinking more than that, what does it mean? And if the tubes have to be replaced, do ALL 3 tubes have to be replaced. And how can you tell IF they need to be replaced. I know i am asking alot of questions but this is cool. Someone to actually help me. Nice...:)

    Good Morning:



    I went home last night checked the red flashing lights in the front of the TV and it is flashing 3 times. So does this means that it is just the Convergences that need to be replaced. Are there 2 of them for my TV? STK329-110, is this the correct one? Please advise.

    Thanks so much for all your help

    Good Morning:



    I was so excited about all the information you sent me and what i needed to buy and do. On Friday i rec'd the 2 NEW convergance for my TV. My husband was so excited, we went out bought the heat sink compound and the solder. My husband carefully took everything about and replaced the new convergance. We were so excited when it was completed and turned the TV. :( We were so disappointed, it did not work. First it gave us a 1 single flash. We shut the TV off, turned it back on and it started flashing again 3 times. How sad is that. My husband removed the board again to see if there was anything out of the norm and he found a very thin gold strip that was just hanging from where we removed the old convergance. Do you think this has anything to do with it? Is there something else we can do to test it? My husband called Panasonic this morning to find out how much it would cost to purchase a new board and they told him $303.49 which we do not have. Please Help :(

Does the light blink? If it is blinking a 3 code, the IC's need to be replaced. Those three lamps as you called them are not lamps, they are the three picture tubes.

    The tube hardly ever go bad at once. That I am sure is not your problem. There is a code for the blinking light. Let me know how many times it blinks.

  • Larry  Dillon
    Larry Dillon Jan 09, 2008

    Yes it is and I would advise to buy the IC's from Here

    Yes they are the IC's you need. If you need a service manual I could probably see fit to send you a copy. I need an e-mail address though.

    Was this shorting against anything? Did you check the pico fuses in the power supply? Let me see a picture of that thin strip.

  • Larry  Dillon
    Larry Dillon Jan 28, 2008

    It is in the power supply. There are two of them on the 24 volt plus and the 24 volt minus power supplies.

    Get the part numbers from the manual. Go to partstore.com. You will need to look on the schematic and see which fuses control the convergence voltages

  • Larry  Dillon
    Larry Dillon Jan 29, 2008

    Your biggest problem is the soldering. You have to have every connection all by itself. These are all shorted together. You for sure have blown fuses now. You will most likely need to get somone who is experienced to solder on printed circuit boards. That's a mess I'm afraid.

The power light is just blinking red on my panasonic 1080i hdtv. cant even switch it off using the power button. picture and sound come on for about a second when the tv is switched on after power cord...


The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

This sounds like a main power board issue. After you unplug it, it will work? Are you planning on trying to service it or having it serviced?
Thanks,

Hello, I have a 53-inch Panasonic PT-53WX42F TV, and it refuses to turn on. No picture, no sound. All it does is the tiny red power light blinks 3 times repeatedly. Can I fix this myself? What parts do I...


Thats a convergence failure when the led blinks 3 times. Your model uses the PT47WX42 convergence repair kit available from www.tvrepairworld.com the kit contains the parts and the CD with instructions for the repair.

My tv does not come on and the red light inthe front flashes 3 ti


The 3 blink error code is indicating that the Convergence ICs have failed. You can get the repair kit for your model which contains both convergence IC and the six feed resistors and it also has step by step instructions with pictures that show how to do the repair. Heres a link to the repair kit for your model.

Panasonic 53wx42, no power, Blinking LED


Have you gotten any solutions to this problem? We had the same thing happen to our TV recently. Haha, maybe they all died on the same day. Before this, we had a convergence problem with the blue color. If you had it fixed, how much did it cost? Our warranty just expired too! Thanks
