Repairing 21" monitor - worth it or not?

Could be a high-voltage problem or a horizontal output problem. If you are lucky, one new transistor will fix it.

As to the worth of fixing it, it depends on what kinds of service shops are available to you. The repair cost would be around $90 - $130 if it is something simple like a horizontal output transistor. After 10 years, it is likely to quit on you again.

My prediction: You will most likely replace it.

If you can remove the back cover, see if there is an orange glow inside the neck of the picture tube. You may need to turn out the room lights to see this. If you can see it, then the problem may be as simple as bad solder joints on the socket on the circuit board that plugs into the back of the tube. This board usually has a metal shield soldered to it, making looking for bad solder joints a bit tougher. But this is a common problem.

often if a power supply detects an short or other problem on one of the outputs then it will shut down. This may be why the relay clicks. there could be a shorted vertical or horizontal problem. In a monitor this old,and judging by the symptoms you mention, the line output transformer may well be bad (recently I have seen several monitors of this vintage with bad LOPTXs) but before fearing the worst, try testing what the other posters have mentioned, resoldering etc. Also check the HOT for shorts, and with it removed connect a 100w bulb across c-e and plug in, see if you have B+.

replacing the other parts, such as transistors etc. will not cost more than pence really if you do it yourself. Only the LOPTX is dearer, typical prices round here are between 20-60=80 for a new one. I wouldn't bother with this if I was workign on a 10 yr old monitor personally.

Nice used 21" monitors on eBay go for about the same price. On the other hand, brand spankin' new 1600x1200 20" LCDs are only $300 these days -- I'd go that route.

the only way to know the price is to get a free quote. Too many variables to predict. I'd avoid the freshly painted looking repair shops as they'll charge twice the price. This is one of the very few industries where going to the backstreets is better.

You'd have to find one local though, shipping alone would be close to $100 these days for a well packed 21" CRT.
