I have a bunch of the old style data flash, and they will not fire the lamp. I installed new SO lamps, and the red led does come on when powered up. I can hear the caps cycling through its test cycle. What do i need to check? Thanks. I am wondering if someone screwed up and sent me HO bulbs even though they are in packages that say SO. I will try taking a known working bulb and installing it in one to see what happens, but i have not had time yet.
You probably blew a fuse....you will have to open the unit up and check the fuses on the PCB inside (don't forget to "unlock" your data XLRs to be able to get inside;) ).

You an very easily tell the difference between an HO and SO lamp.
The HO will have a glass bell-jar "cover" over the flash coil, whereas the SO lamp does not have this cover and the flash coil is unprotected in this manner.
It definitely sounds like either a blown fuse or a blown board.....the board is usually very obviously burned when it fails.
What about the lamp sockets and the lamps themselves? I've seen a few lamps have tiny holes or fractures that were really hard to see. See if they are set to 120 v. Make sure the XLR lines are 'locked on'. Seen a bunch not fire because the were not. If it all looks fine and the lamps are fine then its a job for the factory boys in Texas.
Titos martini party at my house tonight yall come!:friday:

I would also try pulling out the chips from their sockets and examining them....I've seen a few cases where the chip burns on the underside and/or the burn at one or more pins is not visible until the chip has been pulled.
Just make sure you take note of the chips' orientation so you don't re-load it backwards.....which will definitely cause the board to go up in smoke!
