Philips 55PP9401 no sound no picture

I have Philips 55" big screen tv it powers up but you can't get any picture or sound I think it has something to do with the video selection switch(that chages it from av1 to ch a &b).

Re: Philips 55PP9401 no sound no picture

I have a Philips 55PP9401 TV where I just replaced the convergence chips, after i turned on the set the picture was still off, i started the intelisence process and after a few moments after completing this process the picture startes scrambling out then disappeared altogether.

The only thing that happens now is the LED light that is usually red and consistend just blinks and you can hear a high pitched noise in the back ground.

Some of the info i have found suggests that this model uses a Hitatch platform and should use the convergence chips that end in 160 and not the 110 numbers.

The ones i installed were supposed to be the ones that the TV originally came with which were made by Sony or is that a lie.

Any suggestions other than buying another TV.

We no longer have the remote for model 55pp9401 and we have a convergence problem what can we do

Here's the Philips support URL for your TV:

PDF download of your Owners' manual:

Here's what Philips FAQ says about your convergence procedure:
Question How do I adjust convergence (align colors)? Answer Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

Press the INTELLISENSE button on the remote (under the flap). During the convergence process DO NOT press the INTELLISENSE button again and DO NOT move the Projection TV.

So, I think you're going to need to order a replacement remote.

it is not reccommended for game console to be played on a projection t.v because projection tv's have three color bulbs in them and the conversion is different and if it happens to work it has been known to have burn the games image in the screen after awhile.. usually the store doesn't tell youthat unless you ask them about playing game consoles on a projection tv
