Re: Philips TV keeps restarting, is this MB the same as mine please?

I'm never comfortable buying a mainboard til I have proven the backlights and powerboard, usually by starting powerboard as stand alone, by using jumper wires or can use resistors for safety, that's WITH cable from powerboard to mainboard UNPLUGGED.

Seems a bit complicated for me but a few days ago I unplugged the cables that link the MB to the powerboard and nothing happened.

ok, Diah said you can enter your own code, I believe him, he hasn't lied to me yet.

Diah seems very knowledgeable to me too, fingers crossed

Re: Philips TV keeps restarting, is this MB the same as mine please?

yes that one, some philips it can be the number on the bottom of the sticker, suppose it could be the top number as well on some, can be a 12 digit string, don't have to match every single digit on the whole sticker but there's about 12 in the string that should probably match.

ok... so I have to look at all the cards I dismissed on ebay now, to see if the numbers on this sticker match. Lots of work in perspective...

ok let me grab a screwdriver to unmount it.

So the ebay one is okay if I put my firmware on it?
Even if the white stickers dont match?

I hope we can find a solution with Diah's instructions

I'm not saying it's a mainboard problem, just answering your question. you need to match up the numbers on the white stickers, not the silkscreen on the board, from what I see on the white stickers, it looks way off.

Thanks. You mean this sticker?
And you think it's a power board problem?
There is another board called TCON, don't know what it is and where it is exactly, but could it be the problem ? (I find one for my model on ebay)

Re: Philips TV keeps restarting, is this MB the same as mine please?

there are error at your measurements.. let do this... yours black DM to TV chassis and the red probe one time at each LED+ let see yours measurement.

[alfonzzo]

Re: Philips TV keeps restarting, is this MB the same as mine please?

There are 4 points labelled "LED1-" and they are all at around 39V
(positive probe on the first LED1+, DC current)

Re: Philips TV keeps restarting, is this MB the same as mine please?

ok they are on the power board not the main board. I'm gonna measure them hold on

[alfonzzo]

Re: Philips TV keeps restarting, is this MB the same as mine please?

I can send you other pics if you need.
So with the multimeter I measure the voltage on LED- and LED1+ ? but where are these points on the board I can't find them. Continuing searching right now

Re: Philips TV keeps restarting, is this MB the same as mine please?

okay... i cant see on the MB CSM point.. if other can see please located for us.
let do it proffisional trouble shotting.. yours TV 2013 and more old. it could be the restart from other reason.. because logo when it show on screen there are no protecting mode.. bur after logo finish start the protecting script.. this way we need to start from LED back light.
you have on the BL socket at PSU 2 channel you need to put yours probe of DM in DC V mode and put the red on LED1+ and the black on LED- then turn on... you need to do the same if you have one more at any channel Led- listed your reading over here please to compare if we do have one channel or line at channel read less or more.

Here are some pics of the board, along with the power board (not sure if it's its name). And a video of the tv's behavior when I plug it:
