Question about Vivitar 285HV Flash

No 'green' light on bacl of my 'old' Vivitar 285

My Vivitar 285 Thyristor with new batteries whines while re-charging (I believe that noise is normal). However, only the Red light glows. The Green does not come on. Now, it used to go back and forth between Red and Green and have a 'chirp' when the flash was ready (I assumed it was fully charged). Now, it still 'chirps', but only the Red light glows. I set the flash to M for manual and hit the test button -- it flashes. I set the flash on 'Yellow' and then aimed the flash unit at the wall -- hit the test button and it flashes and the Green light (not the charging Green light) came on saying there was enough light. So, is the Flash completely charged and the Green charg light burned out or is there another problem?

Then I'd say it's a reasonably sure thing that the green light is just burned out, The lights are supposed to be off at first, then red when there's a partial charge, then green when there's a full charge, then flashing between red and green when the "battery saver" kicks in. If you're seeing off, then red, then off, then flashing red, then that means everything in the charging circuit is working perfectly, there's just no green light.

My vivitar auto thyristor 550 FD wont turn on

If the corrosion was from alkaline batteries you may use a damp cloth. But before you do that, try using a wooden pencil with a red rubber eraser. This is likely to remove the corrosion without risk of introducing water inside the flash.

What is the diff between a vivitar 285 and a vivitar 285hv?

285 has high trigger voltage(+250v) ,where as 285 HV has less than 5.5 volts trigger voltage (which is safe to be used for any digital SLR2_bing.gif). 285 HV has a Thyristor circuitory.

285, red/green lights blink, whines on start up, but won't fire

Hi Dave,
Try shorting out Center Pin to Outside Metal Contact after the light turned green. This must fire the flash.
If not, could be the flashtube /or trigger are defective.
Do you have a DVM?

Older Vivitar Flash for new Canon SX10

Not compatible.
Get slave triggers and use them as remote flashes, or buy another film camera.
It seems Vivitar no longer is in the flash business. Get a Sigma or Sunpak digital flash for your SX10

Vivitar 285 not working

You don't need a Manual.
In 285 HV there is only one Power on/off switch.
If that switch is on and batteries are new Alkaline (like duracell-no chepo )or fully charged and working rechargebles,and yet the ready light do not come the flash has defect inside.For sure.

Will not flash red/green

This means Battery is low to charge the capacitor.
I suggest you test this with unused new Duracell.

Vivitar 283 charges but fails to flash

I had the same problem with my early Vivitar 283 flash.  I discovered that the thyristor on the trigger board tested as an open circuit. 

Trying to find a replacement for a 30 year old thyristor semi-conductor proved to be fruitless. 

My solution was to purchase a broken, late model Japanese 283 flash off of ebay and transfer the trigger board to my early Japanese model. The late model thyristors could handle more heat.

Problem solved.
