Total guess, but probably and aging electrical component like a capacitor taking time to reach fully functional spec.

BAd G2 board, bad video board are possibilities. I've got spares for cheap if you need them.

Hi curt
I have all the spare parts that you sold me.
Including G2 and video board
Do you recommend to already change them? Or maybe the problem will go away in time. (Didn’t use the Barco for a long time)
Thanks

Run it for a while, then start changing boards if it doesn't go away.

Either one. With a fault like that, the problem could be on any one of multiple boards.

All barco boards simply pull out. Check the FAQ/Tech tips section on the main site for more info.

Thats what I love about CRT. The design is modular and most boards are easily accessible for swapping out even in situ when ceiling mounted.

And above all I had to replace the HV splitter also. It generated an electric leak off 35KV like a lightning inside the projector. Didn’t believe this animal would survive that. And it did!
