Definitly a hole, this is a 5 volts regulator ?? you can check icl 7107 datasheets voltmeter ic, pretty common, you will be able to find the resistor value. too test the display put regulated 5 volt on c13 side going to the busted regulator pins, youll see if the chips and the leds are still good.
Theses regulators normally go up to 40volts

so something bad really happened.
Do you have an complete schematic link ??
The first op thread about r38
Normally this psu has a floating regulator section over the main supply, the common point pass thru R38 ?? but i find it slighlty strange.
I begin to doubt they arent well designed in some way if you have them all failing at some point.
