That problem is usually cause of faulty capacitors on the power supply section..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV. 2. Look at the power supply board..Its normally connected to the power cord.. 3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors.. 4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value.. 5. Some of the capacitors not bulged so its better if have a capacitance meter
You need to know if the speaker on the set is good. Try this, with the set turned off, "rig a 1.5 vdc battery with 1 lead to the + and another lead to the - signs. Touch one wire lead to the plus side of the speaker connector and "tap" the other lead to the minus speaker connection.. You should be able to hear a "rasping" sound coming out of the speaker, that is, if the speaker is good. If the speaker is bad, replace it.
If the speaker in the set is good, then check the Audio output transistor and the audio driver transistor. Check for cold solder joints close to and in the vicinity of these two components.
Another alternative to checking the speaker is to get a small AC-DC transformer, like those used to charge your cell phones. Use one that has an output of 1.5 V dc to safely check the speaker(s). Good luck!
If your DVD player is connected to your TV with a SCART cable, your TV should switch to DVD input when you insert a DVD and press' Play'. If you are connected with a standard co-axial aerial cable (fly lead) this wont work and you will need to buy a SCART cable (or new remote) if you wish to continue using your DVD player with this TV.
If your television is not blinking light or giving any signal that it is plugged to a power supply, it simply means the television is not not receiving any power from the power source.
The problem is that the power panel of the television is bad and need to be replaced, Have a repairman replace the power panel and the television will be in good condition once again.
You can also replace it the DIY way, which simply is that you will have to unplug the television, then you unscrew it open, trace the power cord into the television and it will lead you straight to the power panel, then remove it from its compartment and assess it, if it has a bad capacitor then replace it by melting it off with a soldering iron and fixing in a new one and soldering it on it.
If it looks burnt, then you need to replace it with a new one.
From your quistion we understand that you need an AC power chord for your tv. Usually most of the TVs today uses 10Amp 400v power lead. The size of the screen isn't matter at all. Normally a 20" TV has a power rating of 80 to 100W. A normal power chord of good quality can be purchased from all electronic spare part shops in your area.
cable connection coming into your property.
and last but not least a couple of minute of your time.
the first thing I would do is connect your cable lead F connector (screw on connector) this should be located next to an external wall. they normally put a horrible box on the wall inside your house.
Once this is connected, connect the scart to the box. this is labelled so you carnt really go wrong. then connect the other end of the scart to the scart port at the back of your telly.
last thing you need to do is connect the power cable to the cable box. Then turn it all on.
when you power the cable box up you might have to wait a minute or two just to let it settle then press the power button on the remote this should automatically turn the correct extension on the tv for you.
Disney = Made in China.... Probably full of lead paint, too!! J/K.. Seriously, though... The laser is worn out and will need replaced, but it is unlikely that you will be able to find a new one, since its a generic Chinese import thats been rebranded. Time for a new one.
