Alright lets work with the speakers. Disconnect all the speakers from the unit. Be sure to mark which wires go connected together. Connect each speaker one at a time to see if you get sound. Once you connect one speaker, see if you get sound. Then disconnect and try the next one. Try this first then I can help you more. If you notice that by having only one speaker connected at a time, then there is a short in one of the speakers, see which one does not work. If none of the speakers work, then you may want to try to see if you can connect an external amplifier to it.

One other problem, you did not mention the year, make and model of vehicle. The vehicle may have its own amplifier and must be connected in order to get sound. One way to find out is use speaker wire and connect from head unit straight to the speaker. Let me know what you try and I will be glad to help again.

Your cd/dvd lens is bad, wont read. Swap it if you have warranty or buy a new player.

If your vehicle has a factory amplifier - you must send it the remote turn-on signal.

The flicker which happens is as a result of a power failure in the unit. Whenever this power fluctuation occurs it causes the unit power to go off and then restart. The restart is what brings about the screen which displays media at the top and the radio display screen. try tracing the cables which supply power to the unit for any inconsistencies to sort this out. Also you can check te use which affects the supply of power to te unit.
Here are 2 links to help with bypassing the brake. The first is a video while the other is a detailed step by step explanation.

hope this solution has been helpful?

The display in these radios is powered separately from the radio electronics.Turn it off and back on with the manual button on the radio the display comes back on. It seems to be a function of the switching logic from the power circuits. So, try this and see if it brings back the display with a couple of trials with the power button. Turn the car ignition off,then disconnect the negative terminal of battery wait for 10 minutes then reconnect and check.But if still the display is not there but radio works then,in that case the radio display connections are got loose.It can be loose from display board to control board of radio or loose from control board to display panel of radio.Both are possible.The radio needs to be removed out of dash and its connections are to be checked.If all checked ok then continue further with disassembling the radio itself.In the radio you will see a main circuit board of the radio.On that board there will be many tiny electronic components.Just look at the components.The one which gets faulty or short will be burned or got leaked or got bulged from its top.It can be easily see,as it will look different from other good components.Also check for any loose soldering.Many a times its case of loose soldering.The soldering points gets loose and the grip of components to the board gets loose and re-soldering the board makes it proper.This re-soldering of whole board procedure is called dry soldering.---

But if every thing looks proper on control circuit board,then the other side of the radio has to be checked.That is the display panel.On the inner side of the radio the wires and connection of display panel will be easily seen.So inspect that parts and check.Any of the one is causing the fault.If any wire is checked loose or you notice cut in between the wires then you can connect external wires to complete the wiring.-----------

This whole procedure can also be done at local car radio servicing and repair centers.They will test everything from wires to circuit board to front display panel.And replace the faulty part,if any located.As you mentioned the radio works but there is no display,so as per this it does not looks major problem.Some times just a loose wire or loose soldering causes this issue.------------

This troubleshooting will help to resolve the issue.This should help.Keep updated.,Thanks.Helpmech.
