Hi,
i live in Germany, my English is very bad. I have a used Barcovision 701s HQ, the Firmware on this Projector is 3.05. Is thie Version known? The Convergence Board is a R7622031, and the Convergence at Adress DEH is not adjustable (I2C error Adress: DEH). The Chip at Adress DEH is not available. Im confused, can you help my?

The convergence board is bad. I can repair it for you if you want to send it over.

Hi Curt,
is this the right board for this Firmware? How much Convergence zones has this Projector, 13 or 25? I think, the Firmware and the board are different.... . The Picture via Svideo is black and white and not coloured - this is the next Problem...
Thanks
Mario

I have no idea if that's the right software, what makes you think it's incorrect? All BArcos have 25 zones of convergence.
Svideo problem-could be a problem on the video input board, but check your Svideo cable. You want to run an RGB signal or component signal anyways, forget about the Svideo signal..

Hi curt,
thanks to reply, the convergence Pattern on this projector has Zones 1 to 9, Zones 10 to 13 are one Zone, Zones 14 to 17 are one Zone, further Zones 18 to21 and Zones 22 to 25. Zone 18 to 21 are bad (I2C Error DEH), this is a 13 zone convergence?????! ? Zones defined at Barcovision 701 User Guide. I have not the Multimedia Version.

Hi Mario,
While I can't help you, I just wanted to say that your written English is not "very bad", it's actually quite good. It's much easier to understand than some English native speakers who don't bother to use punctuation and capitalization! Good luck with your projector.
Ben

The only Barcos that used less than 25 zones of convergence were the old Barco 700s, but those old convergence boards had 761XXX part numbers, not 762XXX. So I am pretty sure that your controller board wil work with that convergence board.
I2R errors for certain zones of convergence isn't uncommon, the board needs to be repaired.
