SONY Projection
Hi all,
I'm working on a huge SONY projection TV, model RVP-6000QM. It's really a nice machine, very impressive high power and high voltage electronics!! Maybe some of you know this model, The problem is the unit will turn itself off after everything from 2 seconds up to 1 minute of operation. The set consists of approx 10 fans on different locations, and each fan has 3 leads. I think the third lead is for rotation-check, outputting a pulse on each lap or similair. Namely, I found a fan in the power supply that won't turn on (sometimes will, but with incorrect speed it seems) so I guess the control logic sense this and shut down the set in order to protect the electronics from over heating. Inside, there's a 2 digit led-display that outputs code "01" when set is shut down, could that mean "Fan problem"? Any info is appreciated, Regards Stefan |

I dont work on projection tvs much (I do LCD projectors) but if a fan is not
spinning at a specified speed then the unit will not turn on or will shut down after a few seconds. Try replacing the fan or see if it is dirty. "Stefan Toftevall" wrote in message ...
