Top 20 Sony MHC-GX250 CD Shelf System Questions & Answers

Does it have a reset button or a fuse? check as some units have one or the other. Also check power cord to see if it is not apart as well check the plug itself. Could be the unit itself not working.

if sony has AUX INPUT then plug in your comp or I phone through LIne out (small mini plug) then select AUX on your sony system

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

It is actually 2 messages being displayed one after the other, "PROTECT", and "PUSH POWER".

>>A strong signal was input. Press the power button to turn off the power, leave the system turned off for a while, then press the power button again to turn power back on.
>>Check the speaker cables in case "PROTECT" and "PUSH POWER" appear alternately again after you turn the system on.

If this continues I recommend you take the unit to a reputable repair shop for a diagnosis.

Mine says that all the time and it doesn't skip like that.. try using some air duster in the back and cd tray.. mine actually quit playing cds at one point.. my friend said it was the "dust cover" or something like that by the eye..

pls solved this problem because i have the same problem too on this kind of unit.... .. . .thanks

This should be because you have not used the player for many years. Does the system eject the CD tray? Use the CD head cleaner CD that removes dust on the laser head if any. Try using the audio CD which are recorded in .cda format and not ion MP3 format.

Og to the link below then click on Operating Instructions. Then on page 10 tells you how to set the clock.

If it is possible to switch the speakers do so. If the left plays up on the right channel then yes you have blown it, however if the other speaker acts up you know that it's the amp that has the fault.

check your connections to make sure they're tight, first. if the balance knob makes a crackling sound while trying to change from one side to the other, the guts are dirty and need cleaned.

a am loop antenna should work.

Check the wires in the back and make sure the antenna wire is still connected!

hello my frien let me tell you that the system wont accept more speakers or diferent loads per ohm if the total load says 16 ohms by channel thats the total can handle so if you ad more speakers the system turns off before it burns or or have a severe damage........saludos

HI,

Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.
clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.Also check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track.

These are the only possible home remedies if you still face the problem then you will have to get it repaired.

Press the Display button (just to the right of the Power button) and this will exit demo mode.

hello you need to clean up the laser or worse is misalaigned expert service...........saludos

There is not reason this would click and not turn on. If it just clicked, it would likely be caused by interference from another appliance, typically a fridge or freezer. The most likely reason is a relay in the internal power supply. It will need a Sony Service Centre. https://www.sony.com/electronics/support/res/manuals/4154/41545841M.pdf It isn't a recorded known issue. Sony are high quality equipment so it is worth getting it fixed. https://www.google.com/search?q=sony+icf-cl75ip+clicks+and+not+working ..
