Bronica EC-TL Problem

[The Stig]

Hi! I´m from Argentina. I´ve recently bought a beautiful Bronica EC TL in amazing condition. It even came with a 6x4,5 back.

I put a roll on the 6x6 back. Shoot it all and was amazing. Everything worked perfectly.

Today i tried to put a new roll and shoot one to test it, but after i shot it the mirror didnt came down.

So this its what its happening, if i shoot it in the Mechanical position (red dot) it works fine. If i take the battery, and i use it on other position (like 1/500) the mirror stays up until i release the shutter with the button (like its suposed to work).

But if i use it with a battery (ive already tried a new one) in any position other than the full mechanicals, the mirror stays up until i set the shutter speed to mechanical.

So... it appears to be something with the electric part right? Some Advice?

Welcome aboard, @The Stig (I guess we'll never get to see the face behind the helmet, in keeping with the real Stig, eh! )
Sorry to hear about your issues with the Bronica. Yes, it does sound like an electrical problem. Have you tried a different brand of battery? Cameras can be picky sometimes. Ask @xkaes, he has encountered multiple battery puzzles recently, which he usually solved by switching battery brands. It's worth a shot since it's usually easy enough to try.

If you happen to be using an old PX28A battery, or an inexpensive one, I'd try a new, name-brand battery. That may not solve the problem, but it would make the battery less likely to be the culprit.

Hi! Ive bought this one. Should i try other brand? Or other type of battery? The thing is that i already shoot an entire roll without problem. And i bought 2, so i tried the new one and the problem was still there.

My understanding is that an A544 is the same as a PX28A. But sometimes batteries that are NEW have been sitting on the shelf for a long time -- and not generating full voltage. You need to test the voltage of the battery you used in the camera.

It measures 6,25 V. Is it okay?

That's PERFECT.

That's PERFECT.

Yeah, i knew it. Im an electromechanical engineer and im guessing the electric signal that times the mirror is failing. I dont have the tools to open it but i will search for someone who does.
