hi,the first thing to check with this kind of problem is the power supply section.this requires opening of the back cover.If you are handy with electronics you can check the voltage present at the power board by using a digital multimeter..
here's the procedure,
Use a philip screw driver to unscrew the cover.once the cover is remove,you can immediately see the power supply board .Powe supply board is where the power cord is connected(make sure to unplug the unit before proceeding)
check the fuses,set the tester to resistance or continuity test.test the fuse you must have a reading of 0000 this means that fuse is good OC means fuse is open.replace the fuse with the same type of amperage it is printed on the fuse...
If the fuse are ok,check for the voltage output of the power board.voltage are as follows,
5 volts DC supply for the mainboard
12volts DC for the audio board
24 volts DC for the screen
when all this voltages are present problem could be on tha mainboard itself and needs a replacement.
If one of the voltages fails then you need to repair the power board check and replace all bulging capacitors and open resistors.you can also replace the whole powerboard It is available online at shoppejimmy.com
good luck and let me know how it goes..

Maybe have to program the remote for your specific model if the controller they sent you is a generic one. Google remote codes and your make model.Try newer batteries and make sure they're the right way round. Sorry for being patronising but you know what people are like. Never sure who's asking.

Someone is going to have to open it and examine the power supply board in the set first for signs of damage or puffed up caps and then check for various voltages, This set is likely to be a problem for parts as all brands can be as they only sell circuit boards, the question becomes which board is bad?
