I have a few digital cameras most just don't work but 2 of them are nicer models first off Minolta Diamge S414 has a problem with autofocus and flash. The camera will show "err" in the top lcd when I try and use the flash in auto mode. It just doesn't flash or take a picture when using it in manual mode. Also it will not focus in auto mode. It looks really clear until I push the button to set the camera then it focuses and completely losses the focus! I took the case off to inspect the flash issue because I'm sick of having to always set up lights to use the camera indoors. I see the flash is connected to a capactor that I'm sure is the problem (it shows no visible signs though) but the cap has "photo-flash" printed on it, 330uf 160v and it is kinda heavy for its size (.5" wide and 1.5" tall). Is there really any difference in this cap than any other? The focus is unexplainable but any suggestions are welcome because my Kodak has the same no flash issue, I've tried good rechargables and new alkalines and even have used huge amped powersupplies considering they need 1.5amps @ 6volts to work I've used 3.0 amps @ 7volts and everything inbetween. I haven;'t taken the Kodak apart yet but I'm sure it's another Photo-Flash cap issue. Does this sound like I'm on the right path or is there something else that will cause this?

Re: digital camera flash and focus problems
Hi zinda,
I think the transistors which drive the transformer could be culprit too.
You should check to see if the photo-flash cap even charges up!
Use a multimeter and CAREFULLY measure the DC voltage on the capacitor.
I have been shocked once by a small .22uF cap charged up with high voltage, it HURTS!!!
Never been shocked again though.

Re: digital camera flash and focus problems
Duh!!! The camera has an LCD screen, TWO inverters - one to power the backlight and one to power the flash. So it's like a computer display.
On the other hand, the the camera has a processor and storage, so perhaps it is closer to a laptop.
On the OTHER hand (Motie), many digital cameras have an output connector that will feed the signal to a TV. So perhaps it should be in the 'TV and Video Sources' section.

Re: digital camera flash and focus problems
As flash tubes require very high current for a very short time to operate, photoflash capacitors are designed to supply high discharge current pulses without excessive internal heating

Re: digital camera flash and focus problems
Since there is no forum for cameras general electronics fits better.
There may be a little High Voltage flash module that you can replace it has the flash cap and the associated boost converter in one little assembly. My Sony Cybershot was designed that way anyway.
The module is mostly SMD stuff which is difficult to service without the proper iron and tips so if your camera uses this design replace the module.
It's not always the cap it could be the circuit that charges it as well. It will require troubleshooting if your camera doesn't use the modular design.
Xenon flash tubes are relatively trouble free unlike the high voltage circuits they need to drive them.Last edited by Krankshaft; 01-16-2011, 03:43 PM.Elements of the past and the future combining to make something not quite as good as either.Comment

Good evening,
I need help with dissassembling my USB Flash Drive (ADATA C008 / 16GB), the problem is that I don't know how to approach this USB Flash Drive dissassembly without damaging the USB Flash Drive itself....11-10-2024, 10:55 AM -
Hi all,
I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
🔥 The Problem Started After Suspected ESD/PD Fault
I experienced a power issue or ESD event through a USB-C charger
After that, the NX20P5090 power switch was visibly burned and was replaced
Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
🧠 What I’ve Done So Far

Hello, I'm stuck in troubleshooting…
The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.
In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
When I press the flash button, it's detected by the system, flash icon appear on LDC display.... -
