Re: Samsung Syncmaster 713N

Ok thank you.

Can you tell me what transistors are those , I need to buy them online.

They are Rohm 2SC4672 with the Q gain option. They are available on eBay 5 pieces for $5 with free shipping, and they do ship to Croatia.

Hi there again , I'm back .

I changed transistors that were shorted , lamps are working fine but I'm so unlucky becouse there is a new problem.

Watch the video:

Re: Samsung Syncmaster 713N

It looks like the ribbon to the T-con might not be fitted correctly or it might need a clean. Double check the connections.

If that doesn't make a difference then I think we need to get you to do some more testing.

Re: Samsung Syncmaster 713N

There should be a cable that is attached to the main board ( signal board, logic board ) try taking it out and re attaching it again.

Re: Samsung Syncmaster 713N

I tried reattaching all cables but it didn't help.

Re: Samsung Syncmaster 713N

We mean the end of the cable where it attaches to the screen panel.
Have you done that end or just the board end.

Re: Samsung Syncmaster 713N

Ok I did that (see the picture to know if we meant the same).

But there is something weird , in my first video I posted , when I turned monitor on it went from white to blue and to black.

Now it went from white to blue then some weird lines blinked and then it went to black.There is some difference now and before but I dont know does it mean anything ? You can see the new video.

Re: Samsung Syncmaster 713N

Not sure what the change on the video means .
No that is not the lvds cable it is the one that goes to the board attached to the panel/screen with lots of wires (Look mainly Blue& white?) in it. Checking for broken pins.
Something I dont think you have done since replacing the transistors is to test the output voltages from the power board (the socket with the black and red cable). These need checking with it all switched on and connected up.
Off topic:
I am visiting Dubrovnic next month how much is a can of beer./bottle of wine/ bottle of whisky in a supermarket.

P.S. Does anyone know where is PlainBill

Re: Samsung Syncmaster 713N

I measured output voltages:

1 - 0V
2 - 0V
3 - 12.98V
4 - 12.99V
5 - 12.99V
6 - 7.93V
7 - 7.93V
8 - 12.92V
9 - 10.94V

Is that fine ?
