FUJITSU PLASMA----FAULTY FAN

[tv john]

Hi guys,I have a Fujitsu PDS 5002E-S  50" plasma with a faulty fan. This is where the frustration begins,because this plasma has 4 fans and the set cuts off [showing 'condition 1 ' first]. Now the 4 fans have seperate plugs,so it's easy to detect which is faulty. If I discon. the plug it still cuts out.
I don't know who makes this plasma,but some edge connectors are marked-TNPA191A.

Can anybody help ?      thanks   tv john
