I have a Barco Data 2 that I picked up in non-working condition for £30.
Fault:
It powers up, but will not display a picture. On the telltale LED's, all light up as normal, but the HTHV led is not lit and the scan fail red led is lit. I assume this means that there is a problem with either the SMPS board or the HV board.
Has anyone had this problem before, and if so, what was the remedy?
There is no obvious damage to any of the transformers and none of the horizontal output transistors seem to have failed, as none of them measure short circuit across C-E, E-B or B-C.
Does anyone have a service manual for this projector? Barco have one, but they want £100 for it, and I am not sure it is worth it for such an old projector. They also still have some spare parts, but the SMPS boards are around £400....... ouch!!
I am reasonably confident with electronics, and I have an electronic engineer at work that is willing to have a go at it, but ideally I need to supply him with some circuit schematics, or at least a good idea of what the problem is.
If anyone can help, please do so. It would be much appreciated.
Thanks in advance,
Tom
