Question about Televison & Video

1 Answer

My TV does not power up when the power button is pressed.

My Panasonic Cinemavision HDTV 1080i (Model #PT-51HX41E) will not power up. The TV worked fine when it was turned off. A few hours later when I went to power it back on, it would not come on. I tried unplugging it and then plugged it back in. When I pressed the power button, I got a clicking sound, as if it is powering up, but that is all. It clicks only once. In order to hear the clicking sound again, I must unplug the TV and then plug it back in to the power source. The indicator light does not come on and no picture comes on the screen.

It's sounds like your lamp or backlight has went out, I suggest reading your manual for service info and look online for a local repair shop.

SOURCE: bad color then no power on 51'' panasonic cinemavision

Check the power light for blink code--usually if this model shuts down the power light will blink in a sequence--3 blinks a pause and 3 blinks is short protection--usually means a convergence circuit problem.

Let me know what you find--I am here to help.

Hi,
All that mess in picture is due to failure of convergence output chips in this tv.
Replace convergence output ICs (two ICs) to solve picture problem. Required ICs are available in Part Store, click the link to have price info.

Problem with Panasonic PT-53WX54J 53 in. Rear Projection HDTV Television - Green Screen


You may have a component failing in the red drive stage possibly the blue as well or even the quadrature stage. A can of cold shot should help narrow the search considerably. It is also possible the red and blue projection tubes are nearing the end of their service life as well. If you have the means to test the tubes themselves, check the red and blue tubes for gas.

Replaced convergence chips, have new problem


Did you check the 2.2 ohm 2watt resistors? As often one or two will blow when the old ICs fail. The 3 blink error is indicating a problem with the convergence circuit still.
