Samsung UE40h6200 Logo then Blank (dead flash?)
Good day folks. I thought I'd ask for a bit of advice on this telly, though I'm pretty sure there's no fixing it. The problem is as follows: the logo shows up and then.....nothing. Just a blank screen. Had a look inside and immediately noticed that someone had been there before me, as IC901, the EEPROM, had obvious signs of soldering. The guy who brought it in didn't mention this and as such, I don't know if that was a repair attempt or it worked for a while before quitting again.
I was able to find the EEPROM and SPI files and tried flashing both of them (the SPI chip being IC1304 tucked slightly under the CPU heatsink), but to no avail, it didn't change anything. True, I didn't have new chips on hand to try, so I don't know if the chips themselves are to blame, despite flashing fine. Recently, whenever doing this sort of thing, I always start off with a new IC to immediately rule out the possibility of a faulty chip - it's probably overkill, but they don't cost a fortune anyway. I didn't have the necessary ones on hand in this case, so I reflashed the original ones.
I distinctly remember having a similar problem in the past with one of these BN41-02156A boards whereby the flash chip dies or goes bad in some way and they're beyond repair without the proper tools and software, neither of which I have, especially since it's a BGA chip and the costs/effort would outweigh the price of a new board. It's like it's not loading the "operating system", since I think of the flash as the "hard disk" and if that goes bad, you only get a logo and then the TV sits there not knowing what to do next.
Speaking of which: my local supplier carries several types of these boards. Despite all being listed as BN41-02156A, I couldn't find one that matches the telly's model EXACTLY, but some come pretty close, for instance they may be for UE50 instead of UE40, or stuff like that, so what exactly should I be looking out for here ? Despite having done board replacements before, I can never remember what exactly is important: the model of the TV or the panel model....ideally both, obviously, but that's not always possible. For instance, I once ordered a T-con board by model rather than by panel and it didn't work. I sent it back and changed it for one that matched the panel but not the model exactly and it DID work....I thought I just blew some money there, but I got lucky
What do you guys think ? Pictures are blurry AF, I know but I took them in a hurry and should be good enough to get an idea.
