The one not circled to the right of the fet that is soldered to the motherboard (not the heat sink)

Re: Samsung 50" Plasma HPT5044 No Picture
Ill try and describe what he replaced- as you are looking at the board from the angle where the component of mine had a hole burned in it- The component itself (the one you pictured) plus a small flat onboard (resistor?) next to it and the right hand FET on the heat sink right above the hole-burned component. There is a kit on ebay to repair and it looks like he did about 1/2 of what that provides.

Re: Samsung 50" Plasma HPT5044 No Picture
Actually, $180 all in- I am happy. When I changed the channel to PBSHD the little menu on the top left said 1080i- that doesn't mean my TV is now 1080i, because of the buffer change right? (one can dream)Leave a comment:

Re: Samsung 50" Plasma HPT5044 No Picture
Ya- this one is for the living room- think I am going to buy some more broken and fix them, hopefully less board swapping and more component replacement next time.Leave a comment:

Re: Samsung 50" Plasma HPT5044 No Picture
Ok,
Here is the rundown- I bought two buffers listed above in the thread, and dropped them off for testing with the Ysus Main to be repaired. He replaced the first FET, the blown part and a small resistor (or onboard fuse?)on the main. I plugged the buffers and board in- BINGO! the tv is working perfectly. SO the 5 chip buffers DO work.Leave a comment:

Re: Samsung 50" Plasma HPT5044 No Picture
Just dropped off the Ysus to be repaired and purchased upper and lower used buffers- will let you know how it goes tomorrow when I get them back. I wrecked the buffers I had so I bought a set of BN96-03361A that according to another thread work fine in these sets. (We will also see) These buffers have 5 IC's compared to 4, so hopefully that means a longer life. Should I add some cooling fans to the back of the set? This will be my personal tv, so I want it to last.Leave a comment:

Re: Pioneer pro1000HD no picture
Yep- bonded tot he board UGH. I'll have to figure out how to recoup my loss on this one, lesson learned.
I think I am going to stick to one or two brands and year ranges to keep it simple.

NVM- The y-buffer boards are non-serviceable.... I will part this one out.Leave a comment:

Pioneer pro1000HD no picture
Just picked this one up- won't turn on, clicks and shut off.
I unplugged the y-buffer from the Ysus board and viola- the bottom half lit up, and I can see the menu etc.
NOW- I cannot find the board number for the Y-buffer, or how to remove it (it is housed in an aluminum frame)
Help! -
Re: Samsung 50" Plasma HPT5044 No Picture
No, no picture at all It starts up, makes the startup sound and chagnes channels/I can hear the channel just no picture. The guy I bought it from described that he was watching and the screen went from picture to black from one side to the other.Leave a comment:

Re: Samsung 50" Plasma HPT5044 No Picture
No picture ever- just sound. I don't know what that component does- tom?Leave a comment:

Re: Samsung 50" Plasma HPT5044 No Picture
Yep, same same. The bottom of my board also looked like it had some heat issues, and the Ysus was buzzing- then when I removed the IC from the ybuffer and plugged it all back in it smelled and the went sparky sparky at this component.Leave a comment:

Re: Samsung 50" Plasma HPT5044 No Picture
LOL There is a HOLE in the top of it. Plus it sparked a little. Yes, it is below (not attached) the bottom left heatsink on the board. I unplugged the upper ybuffer, left the low one plugged in and it stayed on with no further exciting moments. It was buzzing pretty well beforehand so I wonder if it was about to go and took the upper Ybuffer IC with it? Or vice versa? I ordered an upper buffer and will send in my Ysus to get repaired- I just want to make sure That's all that is needed so I don't blow any of my new parts!Leave a comment:
