NOTE: if image fold horizontally the section that you have to worry is VERTICAL!,in this case i suggest resolder the vertical (IC some TDAxxxx)and is a good idea to change it.

This seems like a leaky output capacitor. Trace the wire from the deflection coils (in the yoke) that leads to a fairly large electrolytic capacitor (usually less than 1000 uf, 220 or 470 uf and rated at more than 100 volts)Replace with new one. Electrolytics have limited lifespan. Take care when working with TV and monitor. Some large capacitor can retain charges even after the power is off. wait about 1 minute or 2 after pulling the plug before touching anything. Good luck

Probably blown capacitors, the 19" widescreen uses 6 16V 1000uF
Do you have a soldering gun? Its not that hard to fix, get the capacitors on ebay for $6-$8 with shipping.

I've had a very similar issue on many Dell Monitors. Mine have been under warranty and they usually send me a new monitor, but I believe the issue lies with the power supply within the monitor.

Monitor took half an hour to warm up, now won't start.

doubtful this is a driver issue warm up is not needed for any monitor. this is a power board issue internal to the monitor capacitors or some issue on the main power board. let me kow what you will do. good luck.
