  • Barco 23b - light engine

    IF my Barco 23B Light Engine is dead. ALL RED PICTURE. What is this going to cost me to repair it or buy new?

    I am waiting to find out if it is a bad LIGHT FILE or a BAD ENGINE.

    Is the cost going to be an ARM or LEG or BOTH?

    As a dealer we're not allowed to quote figures publicly; but I'm afraid that it is the priciest part in the projector to replace, and by a big margin. The figure will be significantly higher for the 4K light engine than the 2K. A return/exchange is cheaper than buying a new one. For a while during the Cinionic days they wouldn't ship an advance replacement, meaning that for the return/exchange price, you had to ship the bad one to Belgium and then wait 6-12 weeks to get it back again. However, the last time I swapped a light engine, they had gone back to the system whereby you received the refurbished one, installed it, and shipped your bad one back to them in the packaging it came in. Hopefully this is still the case.

    The bottom line is that your best bet is to contact your local dealer for a quote and details of the logistics of the return/exchange deal.

      A all red picture is not likely to be caused by a dead light engine. Didn't you just replace your ICMP in that machine, or is that another one?

        All red can be ICP (or like board) or a bad formatter and its contacts to the DMD itself.

          Play with test patterns, the calibration ones. Do you have primary colours? Do you always have red even when black is selected?
          If you have an ICP, try tapping on the faceplate itself with your finger, do you see any changes?

          It could be a few things - if it's the engine yes, probably an arm OR a leg won't be enough ? Barco used to provide repair/exchange engines, but it wasn't always available. I don't know, I was just an engineer ?

            THANK YOU FOR THE ADVICE. This is a 2K Barco 23B and YES I just installed a used ICMP-X in it. I am doing a Diagnostic Report within the hour. It is strange that I have a GREEN TAIL LIGHT and NO ERRORS. I have seen this RED SCREEN before on a Barco 2000, something had happened to the COLOR FILE and it was a five minute fix (after I stopped screaming at the machine)

            Do you always have RED even when black is selected? The BARCO INTERNAL GREEN TEST FOCUS SCREEN APPEARS AS A RED TEST FOCUS SCREEN. Let me check again on the BLACK but I think it is only BLACK.

              When I tested it, I only had a few minutes as the power circuit was incapable of powering the lamp for long (unbeknownst to me, testing it in a warehouse with temporary power). White was red. Red was red. Blue and Green were black. I didn't get to the uncorrected patterns before the circuit breaker ended the testing.

                That would suggest that only the red formatter is operational, and that blue and green are not working.

                If the fault presented immediately after you installed the ICMP, that would seem to suggest that it's not a light engine fault. I wonder if the ICP side of the ICMP contains the formatter firmware for a different light engine (especially if this is a used ICMP), which is causing it to be unable to drive the blue and green formatters? Maybe try reflashing the ICMP software/firmware package, and if that doesn't get you any further forward, the projector's package as well?

                If still no luck, if it were me, I would put its predecessor ICP back in (assuming that it was working OK when removed) and try the test patterns again. If all three colors are good, the fault is in the ICMP.
