PHILIPS 50PFP5532D-05 Image Issue

[Andyd1970]

Hey Guys,

Another one to tax the brains! Just started one day to give a picture as per the attached image, sorry it was taken on my phone as the TV is at my friends house and is soo heavy we decided to leave it alone till we know if we can fix it.

The sound is fine, all connections externally have been checked.

Bad digital board. Does it affect all menus and all inputs?

Hi Tom,

You are a super star helping me, thank you.

I ahve checked with my friend and he gets the same image from any external device and also when he uses the TV menu's he gets the same image.

So, the lines cover the menus on the display?

I have spoken to my friend and yes you get the same image when you select the TV menu and also if you plug it into an analogue aerial.

Hi Tom66 and all you other great guys,

Any thoughts on this Plasma? what ever you select you get this banding over the whole screen. Just wondered if any of you have seen this before and if so can you suggest a part to order? Its just my friend is getting ear ache from his girlfriend as the TV is on the floor as it is sooo heavy and difficult to put back up, he doesnt want to put it back up till hopefully it can be fixed

It is a control board issue. Only way to be sure of the part is to open it up.

Re: PHILIPS 50PFP5532D-05 Image Issue

OK great, when I open it up what should I be looking for? voltages etc?

Andy.

Your camera, to take pictures of the chassis. Everything is working apart from those lines, so it's not going to be a PSU issue.

Re: PHILIPS 50PFP5532D-05 Image Issue

Hi Everyone,

As requested pictures of the chassis..

Any suggestions?

Thank you Andy

PS - Its realllly cold in East Kent today

Re: PHILIPS 50PFP5532D-05 Image Issue

Here's the control board.
Can you remove the main board frame, and get a closer shot of it?

PS - It's extremely cold in Leeds.

Hi Tom,, See pics of the PCB.

Re: PHILIPS 50PFP5532D-05 Image Issue

See pic.

Power OFF and unplugged.

Place HDD setting jumper across pins 3-4 of the 4 pin block CN2007. A piece of bent wire works too.

Disconnect LVDS, the glued connector, at the main board end (not on the control board... the glue will make it a nightmare.)

Power ON normally.

Test patterns should appear. Do the lines cover the test patterns?

If YES: Control board 100%.
If NO: Main board 95% or Control Board.

Hi Tom66,

Just did as you suggested and the banding was still there. So guess that proves control PCB, just go to find one now.

Re: PHILIPS 50PFP5532D-05 Image Issue

Can we see a picture of the test patterns?

If I were to guess a particular fault on the control board I would say a problem with the RAM or BGA bondings on the processor. I note it is around £50 from several suppliers.

[Andyd1970]

Re: PHILIPS 50PFP5532D-05 Image Issue

Thank you Tom ,your a star.

When you say bonding could it be a cold joint? is it worth reflowing anything?

What suppliers have you found that have the PCB?

Thank you again

Andy

Re: PHILIPS 50PFP5532D-05 Image Issue

I would give reflowing a go -- nothing to lose.

eBay was £50, this guy has two:
