I need a manual for the Samsung UE32D5500R

By: Hiruzen on Apr 12, 2026 12:11 PM EST
Guys, please help out with some advice or documentation. I’m dealing with the classic issue with the D5500 series—the TV is stuck in an endless reboot loop. The logo lights up, then a couple of seconds later it starts all over again. I suspect corrupted firmware or a power supply issue on the motherboard, but without a detailed service manual, I don’t want to start taking measurements. I’m trying to find a decent service manual so I can at least test the checkpoints on the board and figure out where the voltage is dropping. Does anyone happen to have a detailed schematic for this chassis lying around? I’m specifically interested in a service manual for technicians that includes a decoding of the LED error codes and the procedure for diagnosing the power circuits.

It seems like a typical NAND memory issue might be the cause, but I want to rule out hardware power supply problems first. Anyone who’s already tinkered with this model, please let me know what to look for first in the schematic? Is it actually possible to revive it without a programmer, just through the service menu, if I can get into it, or is there a hardware issue? Thanks in advance for any tips!
