So after replacing the H-board everything was fine. https://www.curtpalme.com/forum_archived/viewtopic.php@t=37632.html
After a few weeks, a similar but non the less different problem started. Whenever the projector is cold, the image flicker in brightness. The red LED on the H-board does not light up and the projector keeps scanning. Both internal patterns, on screen menus and external sources are affected. No difference what resolution I run. H-size is also too small when cold.
If I let it heat up for about 5-10 minutes the problems slowly becomes less and less to go away completely and H-size is what I set it to.
I tried blasting the boards one by one with freeze spray to see if I can trigger a flicker but no luck. Felt reluctant to run the EHT and SMPS too cold with my face nearby and I haven't reached into the neckboards and motherboard.
Any educated guesses?
