Hi,
I bought a brand new Sony Digital DSC-H10 camera in 2008. The Flash stopped working in 2011.
I am not a camera tech. I ordered replacement part from Sony and replaced the entire flash board after sustaining many initial high voltage shocks.
The flash did not work. Some forums suggested the capacitor could be faulty hence I ordered a new capacitor from Sony and replaced/soldered it carefully.
I gave the capacitor 2-3 days to charge up. I also touched the capacitor leads to check if the capacitor was charged (I decided to endure another shock) But no the capacitor is not charging.
The flash strobe pops up but does not flash. This tells me that 1) the capacitor is not faulty 2) The Flash board is not faulty 3) The camera battery has no problems 4) The camera works fine without the flash
Here is the issue: Something is preventing the Capacitor from charging. Maybe the circuit board or some other channel.
What could be the problem ? Is it possible to jump start the capacitor some other way internally ?
Please advise. Much appreciated.

Hi-
I own a couple of Sony digital cameras myself.
I have no idea how to repair digital cameras, just classic cameras, which is the topic of this forum. Maybe someone here can answer your question but you would likely have better luck on a digital camera forum. |

[...]and replaced the entire flash board after sustaining many initial high voltage shocks.[...]
It is, unfortunately, likely, that you have (not intentionally) fried part of the circuit *controlling* (not *powering*) the flash. Simply by redirecting some of the high voltage (through your skin) to a part of circuit not made to handle it. This is a common mistake and has totalled quite a few cameras...
Otherwise, not having experience in, nor - apparently - tools for troubleshooting power electronics in a safe way you are out of luck. Sorry.

Thanks Michael.
Thanks Mareklew - Thanks for your advise. I might try and get the main circuit board replaced. This time I wont zap myself. Have learnt my lesson. |
