**BUMP** Anyone have any clues regarding this flash unit?
Thanks!

I tried checking the resistance on the flash bulb (while still in circuit), but didn't get a reading. I'll get around to disconnecting it - might as well rule it out.
While we're at it - you mentioned building a little circuit to test the 602A. What did you have in mind?

Could the flash bulb have gone out? I was told that the previous owner plugged it in, there was a pop and a smell of smoke. I guess you could see why I attributed it to the burn marks on the 602A.

You should make a test circuit for that omnephase according the datasheets, with that it would be sure if that working or not. Is the incadescent bulb still good? The incandescent is still good. I could use some help making the test circuit you're describing. For arguments sake, say it's still good. If so, what part on the board would have gone bad?

This might already be an old thread, but...
Have you tried resetting the cmos jumper? Clearing the cmos can fix a world of problems. It's usually near the battery (but not always). With the computer powered off and unplugged, hit the power button a few times to discharge the power supply. Move the cmos jumper to the reset position, leave it there for about a minute, then move it back to the original position. Powering up with the jumper in the reset position can damage your mobo, so make sure it is back in the normal or running position.

So what type of bulb it has: incadescent, xenon, or? One incandescent, and not sure of the flash is considered a xenon or what it actually is. Attachments:

Normally you can't measure continuity neither on diac and triac. I thought about that, but the scorch marks on the back looked ominous. I've also talked with a flash repair center, who told me most of the time it's that part that goes out. They wouldn't sell the part only - they wanted the repair job, and it's not worth the cost of shipping both ways plus the repair cost when this is an older unit. In response, they suggested bypassing the flash unit and just using it as a modeling light. I'm not sure how to do that, and felt that obtaining the right part and repairing the unit would be simpler and I would trust it more. The part is on that small board, and that looks like two (red and green) capacitors (?) next to it. Otherwise, I would cannibalize it and take it as a total loss. I'd much prefer to fix it for photography use.

Thanks for your response. There was no continuity between any of the legs, and it looked burned.

After looking at the datasheet, I'd say this is a universal "light-dimmer" in a small package and without the variable resistor included. Does that mean a replacement is NLA? If so, is there a way to combine a light dimmer with another component to achieve the same thing? I thought it was used to activate the flash. It's from a Normark Norlite 400, which is a combination flash unit/modeling light.

Thanks, MT! I appreciate your efforts on this. I'll study the datasheet, but I'm not sure if this is considered a standard triac or whether it's something else altogether.
Any flash repair place would only demand that I send the unit in for repair, and it's just not worth the cost including shipping.

Check with Onkyo about their extended warranty program. If you're the original owner, they may repair it for free, though you may have to pay for shipping one way. The issue is often the HDMI board, and when it goes bad, the unit produces no sound. Onkyo and Integra had a zillion of these defects, and Onkyo had no choice but to offer the program, though they've done it very very quietly. From your posting, it sounds like you're the second owner? Still, it's worth asking about, since they base acceptance on the serial number.

Hi, This is from a Normark Norlite 400, a photographic flash and modeling light source. I think it's the flash controller. I can't find it anywhere, and I think the original manufacturing company Omnephase is out of business. Possibly a proprietary part? Thanks! Attachments:
