I tried the BD808 with the new board on port 5 with an RGB computer input. It had the same wavy distortion.

I wasn't positive that the 801 H board didn't have the same distortion, so I just tried it again to make sure, and the 801 board in the 808 did NOT produce the same distortion.

The weird thing about it possibly being a compatibility issue is that the "new" one you sent me looks more like the original than the 801 board does.

Alright, so the board that Curt sent me seems to have fixed the problem. I put in the new horizontal output board, and it seemed to be working fine. I tested it for a couple of hours. I used the projector for the past 2 days and it worked perfectly.

I'm not sure if it's related, so I'm still posting it here in this discussion. But in between programs, (I run a planetarium) I put the projector in standby, and then remembered that I still needed that projector on, so I turned it back on by selecting the input that I needed. When it came back on, the convergence was off! I've had that happen before, and was able to simply select another input, and then switch back to that input so that it would remember it's settings. But that's not working. The convergence is still wrong like the rasters have slipped horizontally. It's the same problem with each input.

So, I tried to fix the convergence, but I'm getting an error. "I2C Error: addr.: F0H"

Any ideas on what the problem is, and how to fix it?

Thanks in advance!

The problem now is the H shift board, that's the FOH error code. You can fake a fix by tweaking the H shift pots for the R and B tubes that are on the top edge of that board.

I can also send you one of these boards, but frankly, tweak those pots and call it a day. THe characteristics of the board won't change, and you shouldn't need to tweak those pots again.

Adjusting the Red and Blue pots on the Horizontal Shift board worked perfectly. Thanks!

Any reason why I should be concerned about a systemic problem since we've now replaced the H output board, and had a problem with the H shift board?
