Tube filament usually means a SMPS issue. No red led on EHT board I would look at the scan fail circuit as it could be vertical board, horizontal board, deflection coils, quad or splitter. If you have swapped out the boards and its still the same then look at the splitter but no heater you need to look at the SMPS.

Ok so if quad or splitter is not working, filament should stay lit when poser on right? So no filament means smps issue only? Or is there other possibility that cause no filament.

If there is no red led on the EHT I guess it is the EHT. Check the fuse.

ok, check EHT and indeed fuse is blown, replace and still blown. Change to another EHT and now I manage to get CRT tube to light up and it display BARCO logo but I can't get any image when source is connected. What should I change out now? Controller board?
