Author Topic: Strong Highlight II turns off mid show Fred Tucker Film Handler Posts: 90 From: Sugar Land, TX Registered: Sep 2007 posted 07-26-2009 08:37 PM                     Been having a recurring issue with a xenon turning off mid show. It strikes back up with the press of the start button. THe equipment is a Strong Highlight II, switcher power supply (the hammertone gray type), analog display board & CNA-200 automation. The fan interlock circuits have been bypassed so this not a paddle switch issue. I haven't been around when this has happened as I am with my Dad in the hospital, so what advice can I give over the phone? Could the power supply be overheating? The plugs show no sighn of scorhing and neither does the wiring harness. Lamp strikes fine and will stay ignited so I dont think it is a ignitor. What say you wiser men?  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 07-26-2009 08:55 PM                       How old's the bulb?  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 07-26-2009 09:03 PM                     Since it's the newer switcher, ask the person on-site if any of the red Fault LED's light up when it goes off...and to tell you which one if any do..also see if the green "GO" light goes out. My bet is dust buildup in that switcher or fan failure and it's overheating.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 07-27-2009 01:33 AM                        I do not care for Strong lamphouses. Not only are their optics insanely difficult to align perfectly, but sometimes the air vane switch decides not to go up even though the air flow is perfectly fine. This is because the flap on the switch is just a touch too small. Put a slightly bigger piece of tape on it and it works. I guess they couldn't afford to put a slightly bigger piece of tape on it at the plant.

Talked one of the guys through swapping the power supply to an old version zero we had laying around & its been running fine ever since. Thanks for the quick responses.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 07-27-2009 04:28 AM                     Bet the in-rush voltage limiters in that v.2 unit is failing. You'll have to send that back to STRONG for a repair/exchange unit. If the v.1 goes, it's a boat anchor in STRONG's eyes. I also had a v.2 (hammertone grey)compact unit do the same and did the same switchout with a v.1 (black) compact unit. No probs sense. Tell your people to switch over to IREM rectifiers. -Monte  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-27-2009 08:01 AM                     I agree, check for dust build up on the switcher intake. This is the best way to ruin a perfectly good switcher. If you find the intake plugged up also be sure to check and clean any others you have in the complex. If it turns out to be a bad switcher I repair them for about half of what Strong charges to do it. I've never had one of my repaired units fail either!!! quote: Joe Redifer I do not care for Strong lamphouses. I pretty much agree Joe... The Super Lume-X is pretty good though and has really flat light if aligned properly. It's good at least until all the wiring gets crispy from exposure to all the UV and IR light. There ARE far better lamphouse options but they generally cost alot more $$.

(We do routinely replace the wiring harness and try to shiled it somewhat from the UV. (It would help if they used BLACK cable ties at the factory.)

They're compact, reliable, have good optics, and are easy to work on.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 07-28-2009 01:23 AM                     Wasn't the "X-90" console based from the Lume-X?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-28-2009 08:26 AM                     quote: Louis Bornwasser (It would help if they used BLACK cable ties at the factory.) And at least light proof covering on the wire or teflon wire so the insulation doesn't disentegrate!! Christie used decent wire and I've yet to see crispy wiring in a Christie console/lamphouse. They also however used those pesky white cable ties!!  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 07-28-2009 12:38 PM                     ..at least they can loom a decect harness out of a bunch of white wires with numbers on them ... Yea, case in point: early X-90 consoles with bleached out wires and crumbly tie-wraps all behind the reflector. Thus the next generation of consoles, they made that plenum to eliminate all of their hap hazard exposed wiring.. -Monte  |  IP: Logged
