Atari ST SC1224 Monitor power button's broken


Recommended Posts

How hard it can be repair the broken power button inside ? The power button is no longer "spring-up" , it just "fallen" in or out when I move the monitor screen down to the ground.

 

Is required to replace "springer" to hold beside the power button stable ?

 

What kind of springer look like ? Can buy the part at Electronics stores ?

If this is the one which is basically a Phillips Mk2 in a new shell you can still get the power button (if you are in the UK at least). Acorn monitors also used the same insides and the switch is available here iirc - <a data-ipb="nomediaparse" data-cke-saved-href="http://www.cjemicros.co.uk/micros/individual/newprodpages/prodinfo.php?prodcode=VAR-8833SW%20(the%20price%20has%20gone%20through%20the%20roof%20since%20I%20brought%20though!)%20,%20although%20it%20is%20slightly%20different%20(it%20has%20some%20sort%20of%20fuse%20or%20something%20on%20it).%20You%20have%20to%20remove%20the%20back%20from%20the%20monitor%20and%20desolder%20the%20old%20switch,%20then%20solder%20this%20in.%20I%20tried%20this%20on%20a%20old%20Phillips%20and%20it%20ended%20with%20disaster.%20At%20the%20time%20my%20soldering%20skills%20were%20terrible%20(they%20aren" href="http://www.cjemicros.co.uk/micros/individual/newprodpages/prodinfo.php?prodcode=VAR-8833SW%20(the%20price%20has%20gone%20through%20the%20roof%20since%20I%20brought%20though!)%20,%20although%20it%20is%20slightly%20different%20(it%20has%20some%20sort%20of%20fuse%20or%20something%20on%20it).%20You%20have%20to%20remove%20the%20back%20from%20the%20monitor%20and%20desolder%20the%20old%20switch,%20then%20solder%20this%20in.%20I%20tried%20this%20on%20a%20old%20Phillips%20and%20it%20ended%20with%20disaster.%20At%20the%20time%20my%20soldering%20skills%20were%20terrible%20(they%20aren" t%20much%20better%20now%20tbh),%20and%20i%20wasn't%20to%20confident%20about%20discharging%20the%20'zap'%20monitor%20so%20desoldered%20the%20switch%20without%20removing%20the%20monitor%20from%20the%20case%20(which%20is%20just%20possible%20on%20the%20phillips%20at%20least).%20i%20resoldered%20in%20the%20new%20switch,%20but%20evidently%20didn't%20do%20a%20great%20job%20as%20the%20monitor%20worked%20for%20about%20six%20seconds%20and%20then%20promptly%20died.%20however%20i%20wasn't%20sure%20where%20to%20connect%20this%20extra%20bit%20underneath%20(just%20about%20visible%20in%20the%20photo)%20and%20so%20left%20it,%20which%20i%20think%20might%20be%20the%20cause%20of%20the%20fault%20(some%20sort%20of%20ground%20perhaps?).%20i%20do%20not%20have%20the%20skills%20sadly%20to%20track%20down%20this%20fault%20:("="">http://www.cjemicros.co.uk/micros/individual/newprodpages/prodinfo.php?prodcode=VAR-8833SW>

 

(the price has gone through the roof since I brought though!) , although it is slightly different (it has some sort of fuse or something on it). You have to remove the back from the monitor and desolder the old switch, then solder this in. I tried this on a old Phillips and it ended with disaster. At the time my soldering skills were terrible (they aren't much better now tbh), and I wasn't to confident about discharging the 'zap' monitor so desoldered the switch without removing the monitor from the case (which is just possible on the Phillips at least). I resoldered in the new switch, but evidently didn't do a great job as the monitor worked for about six seconds and then promptly died. However I wasn't sure where to connect this extra bit underneath (just about visible in the photo) and so left it, which I think might be the cause of the fault (some sort of ground perhaps?). I do not have the skills sadly to track down this fault :(

The link is broken but I have some of those switches that I picked up when my local electronics store was clearing them out.

Caterpiggle, if you have a picture of the switch in question that would help determine if it is the correct replacement part.

Left monitor's button is pressing fine as normal. Right monitor's button is broken. See the version of SC1224. I think it is JVC Style ? I recently re-checked at the back of both monitors. It doesn't say which company made this specific stylish monitors. SO I think it is JVC..

 

Please correct me if I am right or wrong.

Hello Mitch,

 

Please check there as I posted 5 pictures above.

Hi. I think that model is a Philips model. The JVC model looks different and has a detachable cable that goes to the ST.

 

Here is the JVC (left) and Goldstar models.

My friend told me that "broken button" is really missing mechanism ! It does not exist there ! Another working ST Monitor does have mechanism there. It make me wonder who remove the mechanism or forget to installed it in Atari Corp ?? Because the plastic button beside is very clean, never take parts or re-glue, nothing. Very clean plastic part beside.
