Re: Samsung QN75Q60TAF Boot Loop fixed but no picture

his problem not about boot loop as before... tv will turn on even if he remove both DT.. the questions there will be no picture... because t-con cut it off before removing the spi or the masking he did.
i wish i am wrong for his sake.

Remove DT601 and DT602 and all of them are not needed, they cause more problems.
After removal, check to turn on the TV without spi and 601, 602.

Ok, I will try that

@diah, it's ok, and I thank you for all the help, do you think the panel is causing the problem and therefore the TV is garbage/recycle?

Now you need to solder a clean spi flash and check with it.

Once I receive it, I will. I ordered new diode packs as well.

Installed both the new SPI flash and the diode packs. Same result. I'm done with this TV, it's going to the recycling depot.

Well it was not a success BUT it's a damn interesting thread with some good info in it.

Wiring Diagram

Hey again, I have another Q60TAF (70" this time) and I've confirmed that if I isolate the any ONE of the following pins, the TV will stop boot looping (but still doesn't show a picture). I've found no shorted caps on the buffer boards. Pins 1, 11, 22, 28 and 82. Based on the wiring diagram of CN1300, which of these pins is critical to allowing a picture to show on screen?
