Dvd home theather system

hello,its the LENS of your dvd player that is weak,so therefore,your dvd player cannot read disc.
All you need do is just to get a new lens and get the dvd player to an authorizes repairer to fix it for you.
kindly rate me if this solution is helpful.

Take care.

Replace amp ics. Check for any dc voltage on speaker terminals. replace ic that correcsponds to that channel. These are PWM amps.

The PWM amp ics are bad. If you have a dc voltage on speaker terminal thats it.

it may have something to do with parental control

the protection feature is for shock protection and will go off if one of the speaker's positive and negative wires are touching check your wiring

Hey guys, just had the same problem and found out it was because I had disconnected the central speaker. This it was creating a back impedance or something and reonnecting did the trick! i.e. check your speaker connections and check that they work... duff speakers could cause the problem too!

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Just purchased system, didn't come with any speakers, but when hooked up to tv get picture and no sound unless I put headphones in.
