SOURCE: Replacing Sony NW-A1000 battery
Using a pair of pliers grab the silver loop on the back of that player. This is pulled up and backwards at an angle. it is held on by an adhesive pad. Once that is off the back just slots off like many mobile phone backs. Please update the question & let us know if the information given was useful to you - Good Luck!

Press and hold mute and return on the player and turn the volume control clockwise, the setup menu will appear after a few seconds.Go thru the menu and do the required disc calibration.Do not mess with settings you don't understand, else you'll create more problems than you solve.Have some good single,double layer DVD ,SVCD and CD for the calibration.

You could have a faulty inverter but
You most likely have a defective CCFL backlight, it may have the following symptom:
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

http://www.icpowerx.com for the Mosfets, you will probably need to replace driver transistors also (not always but sometimes they go). Also check the resistors to output, they will be the big white ones.

Just to be sure. If one is blown, replace all

This is an error massage and comes when home theater got some internal problem specially in amplifier output section that can have defective output IC etc.
It is not user level repair and requires qualified tech for fix.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.
Overloads can be from excessive periods of high output 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 'naked'. 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 hands-on tech.
