An 11.3 MB PDF for the Samsung BN44-00522B power supply board. The BN44 prefix marks Samsung's TV power board series, and the B suffix is the revision, which should match the sticker on the PCB since different letters can change component values. The size suggests a full set of detailed sheets. Use it to trace the PFC, standby and main output rails, find test points and check for shorts on the primary side. Open it in any PDF reader.
