Dear Rodneysccx,
In download area u will get schematic & service information. Is filament glowing & still u don’t get raster? It could be NVM error or SDA, SCL error. Check all of these links for dry joints. Enter service mode & open self diagnostic function u will get some idea.
If there is no EHT being generated check pin 48 & circuit around it of TB1251. Check R470,too much voltage drop across it activates OCP!
