Exclamation Yaris 2001 stereo problem

I have a Yaris 2001 UK digital speed gage.
I have a problem in both its stereo CD player and radio, when i turned it on I hear its sound very clear and after about 5-10 minutes the sound began to decrease until it disappeared completely, if I push the windows up button the sound appear again for a while then disappeared, with repeated pushing of windows up button for about 4-5 time the sound will disappeared forever.
When I shut the engine off for about 15 minutes and then power the engine on the same of above will happen again!!!
This problem applied for either radio sound or CD sound.
I've try to solve this issue by removing the battery heads but nothing happened. Also I've unplugged both CD and radio from the dashboard and remove its connectors searching for bad connection of weak wires ... again I did not find anything unusual, I've checked the fuses and all of them working fine.
I wonder where is the problem whether it come from the amplifier or from speakers ? or there is a problem in the wires connecting between speakers and the amplifier ?

regards

Finally I found the problem and I fixed my stereo
I've picked out the stereo out of the dashboard and open all the screws also I've opened the metallic shield and pick out the CD drive out of its box
There is a chip with about 20 pins located on the right posterior corner which was fixed to the heat-sink by two screws there was some rust on its pins and some whit salts and humidity. I cleaned these pins by a brush and every thing worked as a charm
