philips 52PFL7203, compatible mainboard?

[sata]

Hi all,
I have the above mentioned TV, with both the T-Con and the main board fried.
Founded the T-Con easily, as it is shared between several other brands of TVs.

The problem is the main board.

I have searched for some time, it seems it's the same boards for the following philips:
7603, 7613, 7633, 32PFL7403, 32PFL7803, 52PFL7203.

It is the : Q528.2E
I can only find the Q529.1E
http://www.lcd-plasma-parts.co.uk/in...69&search=q528

It's the same board likewise, with the following diferences:
-There is no mpeg chip as seen on the image, a STi7101;
-Has 3 hdmi, mine only has 2;
-Has the new NXP PNX5100 processor, mine has the PNX5050;

From all that i can find and read about them, the mainboard i can find is actually a upgrade, the PNX5100 has better image quality.

My questions are:
-What is the STi7101 chip used for? Do i need it for normal antena and hdmi connectors?
-Could i put this newer mainboard on the TV and expect it to work?

I didn't even found a picture of my board trough googling, to show it to you guys. I could post a picture of it if you find it usefull.

Hope you can help. Best regards,
Ricardo

EDIT: forgot to mention, on that site they mention that board they have is the Q528.2E, but on other site it's stated as the Q529.1E, so i'm mostly sure they are wrong, but hey...

Is there a Philips part number that begins with something like "313"?:

Edit: I saw "313912363411V3" at the site you provided. It looks like the board I found could be a match, but they may not ship to Portugal.

Yes there is: 3139 147 26571J#

That mainboard you just posted is like the previous i have found.
Just found one exacly like mine: http://chipart.ru/lcd_tv/lcd_tv_main...004461127.html

Only 2 HDMIs, and "that" chip that i can't find on the ones i see for sale, i wonder if that chip is necessary?


EDIT:
So far, what i understand about the various modules of LCD monitors, as long as i use a T-Con able to drive the LCD, i can use any mainboard, it just has to be pin compatible with the T-Con.
If i use a Mainboard of a samsung monitor that uses that same T-con, i will get the LCD working, but it will be recognized as a samsung, and will be a samsung, only diferent of the exterior of it.
Probably not that straight forward, but...

Feel free to correct me if i'm wrong!

So it seems the missing chip on all those boards found trough the internet is used do decompress mpeg-4 with usb pens.
I will only use the TV with Antena, or HDMI with computer, so i will not need it.

I will buy one of these main boards, and i will post if they are a match

OK, Got the boards and assembled the TV. No go.
A red led blinks for 9 times, stops for a bit, blinks 9 times, etc.

Anyone have a clue? Am googling at the moment.

Thanks all!

Ok guys, repaired the old mainboard ( Can't get the new to pass the led 9 blinks).
Now i get this image:


Does anyone have an idea how to proceed?

It looks like it might be a failed gamma chip, but they don't usually have that bright of colors. I'm curious what was wrong with your main board and how you repaired it. I've got a Phillips with mainboard troubles that is about impossible to source a replacement.

Re: philips 52PFL7203, compatible mainboard?

Hi, the mainboard has a FET that turns the supply for the T-CON.
On my mainboard, since it was burned, i replaced it with a short-circuit, making the T-CON always On.

Ordered a gamma chip to replace the one on the T-CON. I hope this is it, because i won't invest more money on this.

Screen diversity code not set correct, not the gamma chip.
