I am working on a Samsung PN60F5500 with now power. No front panel LED and no response from the remote. The PS PN: BN44-00601A did show standby voltage. We anticipated the main board PN: BN94-06194B was defective.
I ordered both the main board & power supply just to be safe .With the boards installed I do have the standby LED on the front panel now as well as the green LED marked LED2000_L0 on the main board that blinks intermittently.
There is however NO screen illumination. I unfortunately do not have a service manual at this time. My concerns are that Samsung often has different revisions of panel and main board and the main I ordered may not match my panel? Alternately the Y-sustain PN: LJ92-01958A could also be defective.
Service manual anyone ? Ideas ?
Model: PN60F5500AFXZA
Version: US01
S/N: Z6VX3CQD600606K
Panel: S60FH-YB03
Any help would be appreciated.
