Hi now I'm two steps away from repairing this TV, the first thing is to solder in place this ICIC7703 (TPS65175B) and need some advice before I start with it. As you can see in the pictures it has tin in the middle, lit needs a reballing ? I'm wondering how I should go about filling up those holes with tin? Or just put bak with just tin on the sticks all around? Any advice is welcome.
the other is the loose Ribbon that needs to be back in place but we may have to take this after the ic chip is fixed...

Hello all a little update now the IC chip ps65175 is removed and it went as you can see quite well because I have practiced with old board that I have under hand . now comes the difficult part or maybe the easiest because as you see in the pictures the old IC looks like it has had tin balls in the middle how do you think should I go about this IC chip
Any tips are more than welcome.
It looks like Short is gone now...

Thank you so much lotas. a very costly piece of equipment. another question: After he cleaned the tin and added flux to place the MMC, I don't see him applying any tin again in the video? Should you do so or maybe he didn't show it on his video?

Hi lotas, I'm really sorry if I've hurt you, it was absolutely not my intention and wise, you don't force anyone to change or keep original programs, I just wanted to learn, hope you accept my apology and share your knowledge with us.

Hi lotas I don't want to interfere in something that I don't understand but I'm being confounded because you saying in post 442 that you have to make a change on CH341A and I've seen on Youtube Sorin (Electronic repair school) prove that you don't need to make any change at all because there is no high ampere that can destroy any component.I would like to understand to learn and i see that you know what you are talking about . explain to me please

Now the ic ps65175 is in my hands and I don't dare to do anything until I know for sure if it's programmed or not, and how do you know? Of course, the easiest way is to try it on the circuit and see if it doesn't explode again but I prefer another way to avoid waiting 3 more weeks

Hello again Lotas, Diah, EazyBone and everyone else who helped. Now this IC ps65175 is soon here and it must be programmed I think as Diah has said "it cant be replaced with RAW one" if so which program and programmer to use ? I have some that I have never used if you can explain I am very grateful

Hi lotas I have ordered that IC ps65175 but it will take very long to get it home. you can't find an equivalent IC that might be easier to get hold of and, above all, faster...
