|
|
I still am using this and it's great!, except the green tube is switching off when the projector is turned. It stays on about a minute intermittently flickering then totally goes off. I have checked the the video board pins and soldered some dry joints, swapped the convergence board with a spare svd800hd but same issues.
I want to remove the neck board but am not sure how to remove he red wire attached. Can anyone help me please! I really want to keep this projector!

Yes, would like to remove the red wire as this seems to be the only way to fully remove and swap the neck boards, I am not sure how its connected

Can you see the other end of it? Generally it will be plugged into the high voltage transformer/splitter and you push down and turn to release but I picture of that would help to confirm.

The red wire goes from the back of the neck board in disappears under the blue/green lens casing. I will have to take off the lens which I haven’t done before and take some photos. I will have a go this afternoon and post hopefully, I appreciate your help!!😀

That red wire is usually soldered at the CRT socket. Part of that white plastic cover slides off, exposing the solder point.

Ahh ha. He speaks. I sit corrected.
So the SIM2's solder their HV leads eh?
Are there any other projectors that solder rather than use the twist connectors?

Thanks Curt, 😊 Ok I am trying to swap neck boards from another tube on the projector to see if the board is where the problem lies. Hope I’m doing this correctly, So I remove the white casing by sliding off a cover somewhere on it and remove the wire (soldered) and remove the neck board that way.
