I think you are very lucky, go to the moma new York city museum, remove the feets, and sell it as an art handwork, they will surely pay you a lot.. (f**k *** them)... -

Real hairdryer has made probably only a partial deoxy together with dilatation that momentarily fixed the gap, but at long distance also for dilatation more balls can have detached, i did not notice the word hairdryer, balls must melt so it is not enough, to be made at home needs at least a large aluminum plate put on a small stove, and also heated from top with a heat gun at least 300w, also flux paste under the chip, needs the "move" check on the chip, check if sourrounding chips / components are still in place, a missing one can have stopped some line to the 25q flash chip responsible...Leave a comment:

Lotas if you are able to read what i say i used conditional, i'm not all day on the forum helping for free, i often check the forum in a hurry for the time i have, i cannot check every thing, since the conditional, user can check for datasheets, he is a technician and has got a computer.. don't put blame on me, if you think this is a professional service you are out of the road, i'm not paid for anything, users are free to get what they wants.. checking for a missing tension IS NOT A DAMAGE, unless you think otherwise... here there are users from different jobs, remeber this.. i don't want to...Leave a comment:

I had time to watch previous pictures only now, watching board A it has some signs of smoke filtered from back of board to the front by the 4 holes of heatsink, is there any burnt component on the back? As for what i remeber many emmc needs dual voltage to be able to both read & write, 3,3v is the basic Vcc and 1,8v is for writing, check around the DC DC converters, on these type of boards, you can easily check most of the choke inductors for DC DC output, plus there are maybe some linear DC DC (single chip converters like LM1117)Leave a comment:

I don't know how is and why the distorted picture, but if you are able to see the menus, and if the problem is the different panel, then you can try to enter the correct panel type in service menu, every lcd panel has a white sticker with the model, i need the photoLeave a comment:

ic1604 is the standby software, it does not contain profile, the settings are stored in the emmc flash, the reason why it can't save is that probably the user partition is not more accessible due to FS error, the most sensed thing to try is to update the software but i do not think the procedure will touch the user partition... furthermore Samsung are protected by all type of serial port programming.. needs direct emmc programming..
PS: ...or you can crawl on the floor to Samsung asking for a repair update, i know they don't give to youLast edited by Davi.p; 07-21-2025, 11:36 AM.Leave a comment:
