    Panasonic HD Rear Projection Model 53WX42F.

    Last night our TV was working. I turned it off. When my husband came home , he turned it on and it had a small burning smell. Then the screen and power went out. We unplugged it for 30 minutes. When we plugged it back in and turned it on it came on for 3 seconds and went back off. The red light blinked 3 times, paused, 3 times, paused.

    I do have a troubleshooting ability, can you give me a couple pointers Please. What to look for, and is it a voltage regulator, transistor, or those big STK ic's ? Again Thank you very much for responding.

How many blinks is it doing? It has a built in self diagnosis code that it will blink. Pause a second then blink again. Count the blinks then let me know.

    It should only blink 1 - 6 times annything further is not a recognized fault that the set is sensing. Do you have any trouble shooting abilities? You may need a manual or call a tech to come in. If you would like a service manual for your set you can get one at the following link for 10.99 they also offer free assistance to help you diagmose your set. They will email the manual if you buy one and request that they email it to you. Hope this helps. Heres the link.

    It could be anyone of the low voltage regulators or even the convergence amp ICs, however its rare for this model to shut down unless both ICs were to blow at the same time. Thats doubtful. You will really need the service manual to actually get to the bottom of the trouble as it will contain the various voltages at various test points to nail it down. As you have horizontal transistor, verticle out line coils and transformers any of which could be the problem. I would say without the manual I would check the horizontal output anfd the low voltage regulators first.

Pt-53wx53 Panasonic Projection TV Turns off


OK< likely one of the new chips are bad or when soldered in you shorted pins at that time----3 blinks is short protection and you are going to find ONE of the light blue 2.2 ohm resistors is open (usually discolored in middle).

Having changed hundreds of chips in this model once in a while you get a new one that is bad---replace both again.

How did you get at them----remove the board or pull the light box?

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.
