Hi, I connected the camera to a power supply which might have been set to a too high voltage. Now there is no reaction of the camera whatsoever (with batteries or with the correct power suppy). I believe that there must be a fuse somewhere in the circuit which might have blown. Does anybody know where it could be? The camera was working perfectly and I do not want to throw it off. Thanx, D.

Re: Olympus C3000 fuse blown?
Hi, I'm afraid that I think your camera is now 'unrepairable' your last option is now to send it back to Olympus, or a camera repair shop for a formal checking and report. If you are insured for accidental damage on your home insurance you may be able to claim thDave Harpere replacement on that if the camera proves to be totallt gone - and they may want a report on it. Sorry to be the bringer of bad news.

Sounds like excessive current being fed into the lamp circuit or lamp itself; possibly due to a short on one of the voltage rails.
If new lamps (regardless of where they are obtained) are being destroyed at switch-on and they are proven to be the correct wattage and voltage rating for your set, you need to find out why, and the power supply is the ideal place to start investigating and looking for possible causes.
Look for any ruptured or leaky electrolytic capacitors, shorted or open diodes, resistors, IC regulators etc.
Determine (for your own peace of mind) if the power supply and associated circuits are the problem or if it's simply a case of a bad bulb, hence the check.
From experience, bad caps often contribute to the destruction of other components connected to them from increased output voltage, resulting in a chain reaction that eventually destroys more parts, and creates shorts on voltage rails. Not always in every case, but generally it's caps that cause the most trouble, particularly in power supplies and high voltage/high frequency areas (e.g. horizontal).
Don't waste (any more) lamps (for now) if it keeps blowing them. Start with the power supply and progress from there.
If the unit is totally dead meaning no standbye light of or nothing on the display its dark, then you may of blown the AC line fuse. This is the first thing to check the fuse is inside the unit you can trace its location by taking off the top of the VCR and tracing the pwr cord to the point where it connects to the power supply, here is where you will find the AC line fuse use a ohm meter set on continunity to check the fuse for open condintion. If open or blown replace with same voltage and Amperage rating as indicated on the board or the fuse itself. If you find the fuse is good then you have a power supply standbye voltage missing and is related to the power supply. In which case it may be cheaper to just purchase another.
hi...if you have plug the TV in 22oV instead of 11V..it automatically blown the fuse..the power supply has this Varistor it will shorted and blown the fuse if detected high voltage....I suggest you replace the fuse and check for any other defective parts in the power supply section....check for bloated capacitors.. shorted power switching transistor... if none TEST RUN..let see if your TV will switch ON...please rate and vote...
You have a diode arrangement in your power supply that converts the AC power to DC power so that it can be stepped up to operate the high voltage power supply of the set. If those diodes are blown, which happens frequently in a storm, then you have no voltage to your high voltage. You are going to have to check that diode arrangement by making a continuity check both ways on each diode. A diode blocks voltage one way but lets it pass the other way, thus producing a DC voltage.
