Baking the whole board ensures that it has evenly expanded, and is still flat while the BGA is re-flowed. If you only heat up the immediate area, the board can bubble up in that area, even making the situation worse as the solder may not be touching. It also gets the part close to the temperature needed, so less heat is requred from the heat gun to melt the solder.
true that most SMD has issue with lose solder joint, using hot air is usefull. But your video seems unreal.. why would you put everything together as if your are 100% sure it will work? I feel you replace it with new board?
Thanks sudukuai it's a well prduced vid, but a little too focused on the rebuild. I think more time and detail on the removal+repair info would be helpful. But your's is the only one with a descriptive (searchable) title that covers all the basics. Well done!
hi i have a similar samsung having the same problem is that all your doing is heating this part and not replacing it ? can i do this or take it in and have someone do this?
@toddwhat It says 100C, not 1000 deg. You bake it first to remove any moisture from the IC package so the chip does not turn into popcorn from the trapped moisture expanding when you reflow it.
HELLO BRO I HAVE THE TOSHIBA 56HM16 THE PROBLEM SI AFTER 50 MINUTES TO STAR LOSE THE COLOR SOMEONA TOLD ME IS THE DIJITAL BOARD ANOTHER PEOPLE IS THE MAIN BOAR YOU SOMETHING ABOUT THAT THANKS
You should of put a heat-sink on the Dnie chip to keep the problem from happening again. Why it doesn't have one to begin with is beyond comprehension. Let's cheap out on a 50 cent part to trash a $2000 DLP TV.
nice job, however keep in mind that it is better to reflow fron the bottom side of the PCB, that way the heat will go directly to the solder balls, and not trough the silicon wafer, wich might be damaged from excessive heat. Adn btw, you kinda suck at Mario bros lol
i got mt tv to work with the same prob i just pushed down on the chip cleaned it nwith alcohol and it worked :)

your full of it why would you hot air then bake it? at 1000 deg? you just replaced the board would have fried the chip
