The Amp section is not working on my CMT-CP11. There is power going to both the CD and Tape player but none of the switches or lights work on the amp section, and pressing the power button has no effect.

If you are recording, there should be an indicator, like a light or meter indicating activity. If none, then your are not recording and the problem is with the system. If you see a visual record meter or lamp, try another external microphone and check its activitiy that way.
You can reset all to factory settings, which may help;
unplug power, put back in switch on with power button.
Then press together "tape", "CD" and the power button.
You may need to reset the clock before it will work.
If you need the manual, here is the link;
check page 26 for the reset if not clear - nothing else in there that seems to be related, but you may find something i missed.
Hope this helps :)
If this problem occurs only at this cd/dvd it's a disk problem. If it occurs on various disks try using a cd/dvd cleaner set, a wet one is better. Follow the instructions on the set. The main idea is to put one drip of the included liquid at the set (usually isopropyl alchohol) at a specific place (like small brush) on the disk surface and play this disk. This way the "brush" will clean up the laser lens and after that the cd/dvd player will be able to read the disks. BE CAREFULL not to put too much liquid on the "brush". In case this don't solve your problem, the cd player needs laser lens replacement by a technician.

Hello Its system control section does not get proper voltage to go on. Just check whether there is 5VDC comes to main system control section. If not, check the 5V regulator IC for damage or loose solder contact.
If your two speakers are working,if ok ,then the problem is in power amp section ,the IC chip there is already defected .changed that IC so it works normal again and some reheating works in power amp.section... rate me as FIXYA
You have one of 3 problems:1) bad solder joints in the amplifier or preamp section 2)defective output transistors/ICs in the power amp or 3)missing or incorrect voltages to the amp section. If the unit has a headphone jack plug in a headset. If you have sound then everything is OK thru the preamp section and your problem is in the power amp. Any competent repair shop should be able to solve this one easily.
