Electronics Forum / Electronics / March 2009Amiga 1084 monitor problem
Does anyone know of someone who might be able to fix one of these in Melbourne? I opened mine up to resolder one of the connectors, and now it's powering up but wont display any sort of image, but I'm fairly sure it's salvagable an I'd hate to throw it out. > Does anyone know of someone who might be able to fix one of these in > Melbourne?

An Amiga 1084, what is that the date of Manufacture or what. Crikey, you might get for it sending it to a Museum > Does anyone know of someone who might be able to fix one of these in > Melbourne?

Most new monitors won't sync to the horizontal and vertical frequencies used by the Amiga computers. Also the 1084 uses a SCART connector instead of the usual 15 pin D connector used on most other monitors. The 1084S version also has in-built speakers. The only non-Amiga monitor I've successfully got to work with an Amiga is an NEC Multisync II, although there are probably others that will as well.

AFAIK it still works. :-) >>>> Does anyone know of someone who might be able to fix one of these in >>>> Melbourne?

The reason I want it to keep going is that it accepts s-video and RGB, so I can run the amiga, the C64 and my neo geo consolized MVS through it. > The only non-Amiga monitor I've successfully got to work with an Amiga is an > NEC Multisync II, although there are probably others that will as well. Yes, the NEC Multisync 3 did too. MrT. Hi, > The only non-Amiga monitor I've successfully got to work with an Amiga is an > NEC Multisync II, although there are probably others that will as well. Many old NEC Multisyncs (e.g NEC 3D) were able to sync to ~15Khz instead of the usual minimum of ~31Khz. Not many monitors though.. Regards, Ross.. The very last of the Australian made woodbox stereo philips 68cm "flat screen" TV's had Scart connectors and also worked as excellent, large screen amiga monitors ;) Those things can be reparied by backyard banana's and last forever.

Any television or video monitor with SCART can be used with an Amiga. You can also use any modern television/LCD television/LCD monitor with composite or S-Video input. The challenge has been to find monitors that sync to the Amiga via a VGA connector at ~15Khz, even today they sell expensive scandoublers for Amiga users that double the ~15Khz -> ~31Khz so that one can benefit from a possibly higher quality display (SCART is not so common in Australia too).

Does it make a high pitch whistle noise because that indicates flyback death. In any case by far and away the most common fault with those is a faulty flyback transformer. Another common failure was the power switch but that was fairly self evident as you needed to keep it pushed in for the monitor to operate. Flybacks can be replaced, and the flyback was common amongst various makes and models of monitors, in particular Philips sourced ones IIRC. >> Does anyone know of someone who might be able to fix one of these in >> Melbourne?

No, it's not that. > In any case by far and away the most common fault with those is a faulty > flyback transformer.

No that either. > Flybacks can be replaced, and the flyback was common amongst various makes > and models of monitors, in particular Philips sourced ones IIRC. Because of my clumsiness in getting it open, I'm sure I've just broken some soldering, but I'm just not adept enough to trace the problem. >>> Does anyone know of someone who might be able to fix one of these in >>> Melbourne?

Checking traces and resoldering is something most people handy with a soldering iron should be able to do. If there any private TV repair people left in Melbourne, they should be able to do it. |
