Blank display on my Sierra Denali 2009

[m_qasem]

This happened to my 2009 Sierra, the head unit screen went blank but the radio is still working and I can increase and decrease the volume and change the station etc., Any feedback on how to resolve the issue other than installing a new head unit? Can I replace only the display without having to replace the head unit?

The amplifier circuit on the board is likely your issue , and or soldered connectors send me a pic with the malfunctioning unit with key on will help me
