Learning to repair Monitors

[Jpau]

hello Guys;

I´d like to start learning to repair monitors from bottom to top, unfortunately  I have no other option, cause here in town nobody does it, no electronic techs, no suppliers no nothing at all, so I need to learn to fix them by myself, any suggestion about where to start!!!?? 


any advice will be really appreciated.

thanks.

i've read about many being fixed simply by replacing (aka "shotgunning") the electrolytic capacitors on the monitor circuit boards.
you could probably find lots of helpful info in BelBenchTech's list of repairs in this monitor repair area.
also there is a forum for the more "professional" techs hosted by Delphi.  Google "slot tech forum" and you will probably find it.
or you could post up the problems and models you are having issues with and some of the more "techie" members will help you out!

I see a few links are broken, but some still good.

As mentioned, often the problem will be obvious (a swollen cap or something). But once you get into other components, IMO you really need some test equipment. A good multimeter is a must. A super high voltage meter (i.e. 40KV) would be good. And an oscilloscope.  If you plan to be doing a lot of this, then it's worth the cost. But if this is going to be just a once in a blue moon thing, then it may be harder to justify the cost.

Monitors are all fairly common in operation (i.e. all have vertical, horizontal, etc circuits). But how they do it can vary from older discreet components (i.e. transistors, diodes, etc), to more modern ones with a lot of ICs.

This is where having a schematic really comes in handy. Otherwise it's just guessing. Depending on your electronics experience, it can range from difficult to impossible without a schematic. And some are very hard to find.

Anyway, I'm not trying to discourage you, but just to point out that some monitors can be quite difficult to repair without the schematics or proper test equipment.

Oh, and once you do find the problem (i.e. a blown trasnsitor) finding a replacement can often be just as dificult. There are places like Mouser and Jameco, etc. where you can still find components, but the days of going to Rat Shack or other local shops are to pick up what you need are gone.

hello folks;

well it´s really nice to see how quickly techs have responded on this topic, this forum is a  really a great source of help and advice,that´s something I really appreciate, to be honest my electronics experience is almost nothing, but as I said there´s no choice for me, and I´l have to learn the matter anyhow!!, well having said this I think my first step is to go and get the proper test equipment as Poppo said.

I´ll be back on this topic pretty often guys, jeje this forum is all that I got.

thanks. guys
