dead ps-42q7hd samsung
Motsey:
Just noticed when I remove the "LJ41-03439A Y SUS" the tv boots up/makes the noise of loading and the led stops flashing!!
Is there any known problems with this part or things to check?
I hope im moving a step closer :dubbio:
Motsey:
How would i remove the Y-MAIN Board LJ41-03439A apart from the LJ41-03440A Buffer? They are connected with clips? but im worried about forcing them apart just in case i damage the boards.
I want to seperate them to test the main board on its to hopefully eliminate the buffer board as faulty.
Motsey:
Managed to seperate them, it was fairly and a little brute force
The main board didnt work on its own but ive decided to replace both but am struggeling to find them both for a decent price.
does anyone know any sellers who sell parts for a good price? I need LJ41-03439A & LJ41-03440A
-Thank you

I tally a samsung ps-42q7hd which is not responding no lights/leds or anything and was wondering any anyoe could stretch me any guidence on investigation the psu (it is modeling separate PSPF441A01A) to see if itis employed aright and thus eliminating it as a accuse.
Motsey:
Good news guys I replaced the LJ41-03439A & LJ41-03440A board and its working perfect, if not better, then it was before.
I will write a small guide on how I figured out the problem and what things I noticed soon to help other people out but this just proved that a flashing light is not always only a cappicators/PSU issue.
-Big big big thank you to everyone
