THANKS A LOT!
Your technician is talking about the horizontal output transistor near the flyback transformer. These things get hot during operation so they are mounted on a heatsink. If you really want to try to repair the monitor, you can take the back off the monitor and read the part number right off the transistor. There are many sources for transistors, although not all parts are easy to find.
I wouldn't recommend trying this repair. First, it's not a simple matter of unplugging a part and putting in the new one. They are soldered in so you'll need some some experience with desoldering and resoldering. Also, while horizontal output transistors do sometimes just fail, they usually go bad because other parts fail first. If you don't have some experience with troubleshooting this kind of equipment, you may be wasting time and money trying to fix this yourself. There are also dangerous voltages present in the monitor, even after it's been off for a while, that can shock or even kill you.
So many people are replacing monitors today with flat screens that you should be able to find one for very little money or even free. If there are resale shops (Goodwill, etc.) in your area, that's a good source. I've seen monitors in shops around here for $10. There are also flea markets, ads in your local newspaper, Craigslist online. It would be safer and less costly to think about replacing your monitor.
