Yes I have. I already tried a fresh installation, the HDMI will work in that case, until a plug in the touchscreen monitor with the DSI cable. Once I do that if I try to use the HDMI again then there will be no signal.Have you added below to config.txt?start with a fresh installation. Still I2C and SPI are enabled (If you need them later you can enable them once the issue with HDMI is sorted).Code:
dtdebug=1
I'll explain with the following steps:
1- start with a fresh installation, HDMI works. Poweroff the device.
2- Unplug HDMI monitor, plug in touchscreen monitor with DSI cable, power on the raspberry. Touchscreen monitor works.
3- Poweroff Raspberry, remove touchscreen monitor, plug in HDMI monitor. Boot raspberry.
4- no signal on HDMI after splash screen
It is as if when plugging in the touchscreen monitor something is written somewhere in the configuration so that the HDMI won't work anymore. It's not an hardware issue because at boot everything works, once the OS is loaded there's no signal.
