Question about Nikon Speedlight SB-800 TTL Flash

1 Answer

Replaced flash circuits

I've just had both SB 800's die, uncannily, within the space of a week of each other, sent them to Nikon and now unfortunately its going to cost £160 each to replace the flash circuits on them both. Considering I can buy new SB800's for £204 w/warranty, is it worth repairing them (they're both under 2 yrs old and now out of warranty) ? Is this likely to happen again in the future? They've been worked hard, but that's what they're designed for surely!

There can be two schools of thought for this.

When replacing the circuit board in a flash, this means that the lamp, photocell, LCD display, and the switch pads are the old ones. I would guess the main power inverter board is being changed.

What usualy fails on this board is the main electrolytic capacitor. Not always, but other parts can fail. If it is only the main capacitor, this can be bought at most any major electronics parts distributor. You only have to specify its value in MicroFarids, the mechanical size so it will fit, the lead configuration, and the Voltage rating.

As long as the voltage rating for the new one is the same or greater, and the size configuration is close, the new cap would most likely work. This type of cap is not very expensive compared to the cost of a complete board.

If other parts are also defective on the board, it may be impossible to service unless the part is a generic type. If the part is an SMD surface mount type, depending on the configuration, someone who has SMD soldering tools can replace the part.

I have repaired about 80% of the problems in photo flashes. I only send them out if the fault requires a complete board change or factory calibration. With a new board, calibration will probably be necessary.

Bottom line for me: I would buy new flashes if I had to pay out more than 60% of the cost of a new replacement. But, that is my personal view.

I am using a nikon D200 with a sb800. The flash is firing ok on TTL and the camera is set on 'P' however I am getting a dark picture every tme. The built in flash works OK It appears the flash/camera...


This is an excellent flash, very powerful and compact and actually more flash then what was available when the D200 first cam on the market. The two will work nicely together and I think the problem is that the SB-800 can be programmed within itself. This meaning with some cameras you program the camera for the flash output with the SB-800 you can program the flash as well. It has some excellent features like Flash value lock (which I think is set to slightly underexpose from what your question is asking) it also has Flash color information and a built in Flash compensation. Possibly the compensation or value lock are set to underexposure. I'm saying this over the camera setting because you stated that the internal flash appeared to be okay, check your SB-800 settings

Why is my sb-800 melting my batteries?


Thre is a non-repairable short in the capacitor charge circuit that puts a big amp load on the batteries.

May be repaired by Nikon service... but the electronics contain high voltage. Do not attempt to repair yourself and I wouldn't trust it even if Nikon repairs it. Why risk burning your camera and equipment!?!

--sorry--

SB-800 -3EV message after about 50 shots or so


IN THE INSTRUCTION MANUAL USING THE FLASH IN SHOOTING FAST CAUSES IT TO HEAT UP .

TRY USING THE FLASH IN MANUAL AND CUT THE RATIO POWER AND USE AS A FILL AND NOT A MAIN .
YOU COULD ALSO USE TWO NIKON SB800 FLASHES IN ITTL AND WITH TWO THE FLASH IS USING HAVE THE OUTPUT AND RECYCLE TIME IS INCREASED .
DAVE BLACK A WELL KNOWN PHOTOGRAPHER DOES THIS IN HIS SHOOTING .
