Question about Panasonic PT-47WX53 47" Rear Projection HDTV

2 Answers

Panasonic Hdtv 1080i pt-43lc14 When I press power the green light starts blinking for about 1 minute then it turns red the lamp light also blinks red. The tv sounds like it wants to work but there is no picture nor sound. the TV makes a little noise but no actual sound coming from the TV. The screen remains black. I was told to order a STK392-110 and solder that in the mother board does that sound right to you? Please help. Thank you, Roland

    does that just happen at random I've had the tv for several years. The lamp went out last year but I don't feel like thats the problem this time. do you agree that it isn't the lamp?

You can try a new regulator, but also check the horiz. output transistor for an emitter to base short, then also suspect the flyback transformer both are located on the deflection board

I would check under all the boards,for a cold solder joint,conecting a heat sink,to the board.This problem occurs more often than you would think.At the ***,plant the robots that put theses babies together,are not as good as a human.Hope this is some help.let us knoe if this helps.Just clean real good,and re solder the heat sink.

Power button blinks green about 1 minute then goes red


There is an additional problem,

if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

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.

That sounds like a bulb. You should pull it out and check it.
Pretty easy to do, but if mine did the same type thing, replaced the lamp and powered right up.

Turn on and Power and Lamp Lights blink.


Just because it doesn't look broken doesn't mean it hasn't failed.
Is the TV over 2 years old?
If so, buy just the bulb (not the whole lamp assy) from us at sedonix.com, install it yourself and save about 75% of what Mitsubishi charges.
