True. It probably is something simple. I checked the capacitor off circuit, and it's at 1126 mfd (expected 1000 mfd) at perfect zero ESR. So that's a good cap. I'm tempted to change the xenon lamp. But, seeing that it's the charging circuit that's at error I'm hesitant. The circuit boards...

One eye Jack, Checked the standby mode. Set it to Auto. Oh yes the 300V cap will be accorded due respect. I read the description of the circuit. I understood some of it. Testing the TTL. Took a few pictures, of course,no way to tell if the flash is ready. The flash didnt have the metered...

I did not previously. So repeated the steps. 1. Installed batteries 2. As it whined, pressed the test button 3. The flash fired 4. Repeated test firing a few times 5. The whining continued and eventually saw the "Bat Standby" sign

Thank you for the note. So I turned it on and set a timer for three minutes. It whined and at around a minute and a half the display said "Bat stby" and stopped whining. The batteries felt slightly warm. This was done twice. 1. With Alkaline Batteries 2. With freshly charged 900mah NiMh...

Thank you one eye Jack. I got locked out hence the late response. The test button didn't elict any response from the Speedlight. After letting the flash whine for 15 seconds, I discharged the capacitor with a led indicator circuit, which indicates that the cap was getting charged, but I...

One Eyed Jack, Thank you for the service manual. I did have a copy of the same. I'll look up the working principle of a flash tube. I'm no expert in electronics though. I can check components and take measurements, and once in a while catch offending components.

Greetings! I procured a beat up SB 600, with the same symptoms viz: 1. Powers on 2. No charging sound 3. Ready light doesn't come on So following the easy to understand and thorough procedure as detailed by Fatigue, I replaced the thermal fuse. I couldn't find the exact replacement. So I...
