Nikon D70 - indoor flash problems

According to an LG installation manual for the LMU540HV, if the flashing light is viewed on the indoor unit with the ceiling cassette light on the far right flashing 5 times, it is an error code meaning there is a communication error between indoor and outdoor units. I would start by making all indoor and the outdoor units have power. I would especially check to see that fuses or circuit breakers to the outdoor unit have not failed. Or check the outside disconnect to make sure it is working. Check with a volt meter to be sure you have 220 volts present to the outdoor unit. Also, if the 4 indoor units have emergency power off switches, make sure all 4 are turned on. Checking to see power is present both indoors and outdoors a good place to start. It the outdoor unit has power, there may be a relay that has failed or a power circuit board has failed that would cause it not to communicate.

1. Indoor unit
(AH-X18MEV, AH-X18MEV-1, AH-X24MEV, AH-X24MEV-1)
To display the self-diagnosis, hold down the AUX button for over 5 seconds on the indoor unit when the indoor unit is not operating.
• The operation lamp (red), timer lamp (orange) and Super jet lamp lighter) flash to indicate the information of malfunction.
(Display of self-diagnosis result)
The operation lamp (red) and the Super jet lamp (green) flash in synchronization with the timer lamp (orange).
(AH-XP18MV, AH-XP18MV-1, AH-XP24MV, AH-XP24MV-1)
To display the self-diagnosis, hold down the AUX button for over 5 seconds on the indoor unit when the indoor unit is not operating.
• The POWER CONSUMPTION indicator indicates the information of malfunction by showing the main category error (number) and the sub-category
error (-number) alternately in 1-second intervals.
Example: Compressor high-temperature error

Hi Usually outdoor picture are good within small compact camera. They designed like that. But now your unit just have flash pcb defective. When flash function work, your picture will be good indoor. Regarding your flash unit would be brown fuse or replacement of flash unit. It is 50 and 50 chance. Your local repair shop would charge around $35 to 95 depend on what they really want to charge. Thanks and best regard!

If you're getting shadows on the bottom center of indoor photos when take with a flash, it is most probably due to the length of the lens on the camera.

A long, telephoto / zoom lenses will create the largest amount of shadow, while shorter and wide angle lenses will be least likely cast shadows. You can reduce the amount of shadow in pictures by removing the lens hood that may be on the end of the lens. The lens hood is to primarily to shield the lens from direct (sun) light, and probably isn't needed for indoor flash photography. Also, rely less on the zoom function of the lens on the camera and physically moving closer to your subject instead. The flash will need to provide much less light output and result in more flashes per battery.

You could use a separate flash - held off the camera so that the lens is not obstructing the light of the on camera flash. Using a Nikon Speed Light, you can set the on camera flash to provide a low output, that would be used primarily to trigger a Nikon Speed Light held by someone or arranged on another surface etc. Youtube is a great source for real life, practical "How To" videos for many operations of the camera and accessories.

I hope this was helpful!

This is a signal fault between the indoor and outdoor first make sure the dip switches are set start with the unit closest to the condensor set as unit 1 then next unit as 2 and so on the dip switches are inside the indoor unit on the pc board if you check the manual it will tell you which swithes to set, if this wasnt done when the units where installed they would have never worked i would also check the signal wiring between the wallmount and the splitter box / bc box and make sure there isnt a loose connection when you have ruled this out id say more than likely it is a faulty indoor board on the wallmounted unt

You should set the white balance to an appropriate setting. For outdoors, or indoors with flash, auto +-0 should be adequate. For indoor work without flash, try the incandescent (light bulb symbol) or fluorescent (strip light symbol) if you don't like the results from auto.

The higher the ISO setting the more grain in the photo. Have you somehow set the ISO to say, 1600? http://www.nikondigitutor.com/eng/d70s/select.php?menu=1&sub=b11&num=12 Select ISO setting this way: http://www.nikondigitutor.com/eng/d70s/select.php?menu=1&sub=b05&num=10 Are you shooting in low-light situations (typically indoor)? Try shooting bright scenes and Auto mode, or manually set ISO to 100 or 200 and see if noise persists.

You're shooting under incandescent light, and the camera doesn't manage to set the white balance entirely automatically. You can try to explicitly set the white balance to incandescent, or you may be able to create a custom white balance (I'm not sure whether Nikon bodies offer that feature), or you can adjust the white balance during processing (in which case it's better to shoot raw).
