On my 2408WFP I have two sets of vertical lines about three inches from the side, and each side. So went I power on, I have them on each side. After monitor warms up after a half hour they are gone. Is there anything I can do to repair this monitor? I love this monitor.
Apologies for missing your post over the holiday. Unfortunately, Dell does not repair monitors, sell monitor components, or have disassembly documentation. Your only option is to take it to a local TV repair center to see if they can diagnose the issue. Then look for spare parts on eBay or craigslist. The cost of repair might outweigh the current market value of this 8 year old monitor.
