HL-S5088W Check the Fan No. 4 (BP94-02258E)

Postby capodi » Tue Apr 26, 2016 12:44 am

I just replaced the main board (BP94-02258E) to fix a "no sound" problem. The TV works except now the flash message, "Check the Fan No. 4" now appears. After a short time period, the TV eventually shuts itself off.

I only found three fans and all are working perfectly; Fan #1 for the lamp, Fan #2 for the DMD board and Fan #3 for the I/O board (attached to the cable card board).

When I disable each of these fans, the appropriate flash message appears for each fan 1,2 and 3 respectively.

I reviewed the Samsung service manual in great detail, and the manual references only two fans - one for the DMD board and the other for the lamp.

So, anyway I can remediated this issue "Check the Fan No. 4" issue?
