it's a 25" computer crt? that's a pretty expensive tube.

whether or not it's worth it would depend totally on the condition of the crt, which you are not able to really look at... what you are worried about is the burn-in effect that comes with all crt's... i have repaired hundreds of crt's, burn-in can ruin a monitor.

I repair all things electronic, mostly as a hobby. You will find it very difficult to find anyone that repairs monitors anymore. They are pretty much a disposable item.

The problem could be many things, but the usual suspects in any device that uses high voltage (most monitors have 5,000 - 10,000 volts driving the CRT), are the capacitors. The electrolytics in the switching power supply tend to dry up over time, and eventually open or short, often taking other components with them. It actually isn't that difficult to fix them: You open the CRT, carefully short all the capacitors (they can contain a lethal charge for hours after power is removed), and then test them one-by-one to see if they are open or shorted. Often, I just replace all of them (about an hour's job, and $20 worth of capacitors). Works about 90% of the time (because the problem is almost always electrolytic capacitors).

However, like I said, most repair shops don't do component level repair anymore. I repair these things partly just because I can do it, but also to keep them out of landfill (most people don't dispose of old electronics in a very ecologically conscious manner, unfortunately).

Thus, reluctantly, my advice is to take it to your local recycling agency and buy a new monitor.

Thanks for your replies. I'll take it in for a diagnosis and find out the $, and let you know. Thanks again, John.
