Repairing 21" monitor - worth it or not?
I have a Gateway 21" monitor about 10 years old.
It quit working. Were it a smaller monitor I would just toss it but being a nice 21" I would like to get SOME idea what it might cost to have this fixed. The problem is that there is no image at all. Everything else seems to work fine however. I hear the normal "hum......click" when the monitor is turned on but no image appears. I hear the normal "voom....click" when I press the de-gauss button. Connecting my laptop to it, it "sees" the monitor connected. However, despite whatever I've tried (including different cables) no image appears. I'm just trying to get a ROUGH idea what it might cost to fix this, to see if it's worth even seriously considering fixing. |

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. |

I'm just trying to get a ROUGH idea what it might cost to fix this, to see if it's worth even seriously considering fixing. 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€ for a new one. I wouldn't bother with this if I was workign on a 10 yr old monitor personally. -Ben |

On the other hand, brand spankin' new 1600x1200 20" LCDs are only $300 these days -- I'd go that route. |

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. |
