This is my first post to this forum, so before I get started I would just like to say hi to everyone, and thank you in advance for any and all help I get.

Okay so I have a Samsung HPT5044X/XAA that was given to me by a relative. The problem with the TV is there was sound but no picture, so I did some research and found on that it may be the Y Sustain board. I replaced the Y SUS board and in that process noticed that the top Y Buffer Board had a severely burned out chip



So I saw on Youtube that if you take out the top Buffer Board the bottom Board might be able to give some sort of image on the bottom of the TV. I hope I explained that correctly. My problem is that when I remove the Top Board the TV still has no picture. So I'm wondering does that mean the my problem is the Top Board? Or something else? Any help would be appreciated, thanks.

Thank you for the reply. I was teetering on the edge of whether I should buy the Buffer Boards or not, but now I think I will just spend the $100 and get them. Thanks again.
