This is a typical symptom of bad capacitors on the power supply board. The capacitors filter the output power and when they start to fail it takes time for them to build up a charge so they can filter the power correctly. Here is a picture of the power supply board model IP-43130A and here is a link to information that shows what needs to be replaced it repair the power supply board and bring your monitor back to full working order.
