Lg 50pg3000 upper buffer

[finntricky]

hi guys, BIG ASK, im looking for a upper buffer board for this 50PG3000, due to me trying to replace a chip on the board and taking of some of the tracks, so now im in panic mode, willing to pay for it, but not £70 like ebay.
EBR50039005 EAX50051102,
can anyone help ?

Thats a tough one, them tracks are very small it is possible but its hard trust me ! I can replace the scan Ics however the tracks curve around to the ribbons and aren't straight so will be difficult to do I would say im willing (if it was the Ic) but unsure how well it would go.

Re: Lg 50pg3000 upper buffer

thanks m8, but putting the IC on has what has caused the problem, i have draged the solder down the legs and must have put to much pressure on it, and bent the legs, so trying to put them back straight has taken the tracks out, not to bad to replace the outer ones, but the others that go under the IC are never gonna be right,
its defo got to be another buffer board

Re: Lg 50pg3000 upper buffer

Yeah, you probably didnt use enough flux or your iron isnt hot enough. Also dont use cheap flux it wont flow the solder properly and will just make it all goopy and mess things up. Also on an Ic when the pins and tracks are that small and close together, if you bend a pin dont try to fix it when its on the board them tracks lift as easy as anything remove the whole Ic, fix the error and start again.

Also £70 ? on a 720p Plasma ? These displays are prone for the PDP module to fail as well. I fixed the Psu on one a while back and turned it on and green row of sub-pixels was out (not fixable) also seen it in others cases with these Tvs. Maybe wait a while and see if one come up cheap, the company I used to work at whole liked to throw boards at Tvs we found one for £20 and it sorted the one we had but we waited a while for it to come up. Its up to you though unless you need to have it done, go for the buffer buddy

What ever you do, dont chuck it out. Its repairable for the most part help Ewaste.

Re: Lg 50pg3000 upper buffer

I think I may have one..but the mosfets are shorted..board is good if you want to replace mosfets..I will verify.

Re: Lg 50pg3000 upper buffer

its the upper buffer board in need, not the Y-SUS, and your in the states, import charges would be very expensive, coming in to uk, but thanks for the offer;

Re: Lg 50pg3000 upper buffer

Import VAT is only paid on items with a declared value of over £18 and import duty on items over £120.

I drag soldered my first buffer IC and bend some pins, almost ripped a coupe of traces too.
Managed to save it luckily and shall solder the individual legs this time round.

Re: Lg 50pg3000 upper buffer

You need good flux and a hot iron to do the drag method, I tend to create a huge blob then wick it off with my iron. To remove the old chip I use hot air that the best thing to use.
