It should be like this, but is it really?

Hi ywh!

I managed to get it work. When i set bulb power to max 😀 and put projector to cool place (0c), i managed to keep it on.
Didnt try that (22c) because bulb/ballast could fail.

Seem to be that component has failed. I think so, what you think? Problem in ballast component?
I had no problem when i had previous bulb, might be that new bulb stresses more (broken) components?

Any suggestion what is broken? Lets buy cold spray and track it down.

Hi ywh!

****
what is (22c) = degrees temp outside projector.
what happen when you short that pole like my picture? = it works as trick should do, power on but same problem stays.
***

Its not temp sensor, 1:st thing i checked.
Notified that its not temperature related problem at all.

I did check projector with cold spray. Didnt find anything.
I added extra 10k resistor to power adjust and get 57k.

It stays now longer on, but see this picture. Cant make it work with that bulb. Help please 🙂
How much voltage that bulb require?
Bulb that you say you sended me was 200W BSM-AC-H.
