Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Question for Guru slinteriors: about Panasonic PT-47WX49 shut-down problem.

It shuts down itself with a power-swtich click sound. It happens after a few seconds or a minute after turning it on. No LED light blink.

Before it's off, I noticed that the blue image shifted shakily to the right. Is TK392 bad?, so it shuts the power down? Other than this, are there any other parts causing that problem, as well? Where could I buy reliable/trustable parts from, any recommendations on comaptible upgrade chips?

Thanks a lot.
Bill

    Thanks, Slinteriors.

    I know your name from many posts about the same or samilar problem. Appreciated your posts/answers.



    For my case, does with or without blinks in power LCD after shut-down make any difference? I guess there is no pin difference in STK392-150 and STK392-110, right?

    Looked around the internet about STK392-150 vs STK392-110. Do I need to replace 6 resistors as well (two with each color) as Hitachi does?
    vbmenu_register("postmenu_361502", true);

    Any advice on using STK392-150 vs STK392-180, to replace STK392-110?

    Slinteriors, you are the man.

    Hi Slinteriors,

    Following your recommendation, I replaced the two IC' with STK392-150. The shutdown problem is resolved, thank you for that.



    But now, the color looks wired. The blue appears Blue-green, just like the color of the 4 diamonds' in the rating scale on this FixYa page.



    Any idea?

    hi Slinteriors,



    maybe I need to do some adjustment on Serviceman Adjustments Modes for CLOCK ADJUSTMENT ?



    very appreciated, if you can email me Serviceman manual.



    Thanks.

The stk392-110 ICs may possibly be bad. I would recomend replaceing the stok 392-110 ics with two STK392-150. You can get replacements at the following link, and they provide free installation instructions

    the STK392-150 ICs run cooler than the stock STK392-110 ics do. Often if the ICs are real bad they will throw a 3 blink error code, but I have seen other times you wont get the error just a distortion of the alignment then straight into shutdown.

    if the led were to be blinking 3 blinks then I would suggest replacing all 6 2.2 ohm 2watt resistors, but when it doesnt blink your usually safe with just the two ICs

    I have seen the STK392-180 ICs not do well in most panasonic models as an upgrade, The 150 seems the better upgrade for most panasonic models.
