While it's doing this, check the DC output of the power supply. If
it collapses along with the image, then it's most likely a power
supply issue. This sort of behavior isn't atypical of a bad capacitor
or ten in the SMPSU.
A lot of consumer displays get tossed in the trash for exactly this
behavior.
