Hi I have Pionner vsx-33tx. everything is good with the reciever but display gets off after while when the device is on. it is not about dimmer button. because the dimmer button does not respond when display gets dark. when I unplug the device for a while after that it Works and display Works properly but again afte while it gets dark. the reciever Works when display is off. any Idea how can I fix this problem. Thanks. Ata
