Sudden partial death of Chinese Double din Bluetooth GPS uni

Hi all hopefully you guys can help me :-)

Unit been fine for years and now wont boot properly. Goes through the boot logo fine and then flashes up with the radio section for about 2 seconds and then goes off. Reversing camera works fine and keeps the unit on. Have opened it up and can see the arm chip is MSB2531. This daughter board has an led that stays on during boot then starts flashing 2 short flashed then 1 long flash it then repeats this 4 times and then thats it. Have tried with the dvd portion off still nothing. Have took the radio from the car to rule out shorts and still no good. When it stopped working it had a phone plugged in the usb charging. The unit had been on for about an hour or so with the car not running obviously ign on accessory position, car was started an all ok then it failed when going through a height restriction that just touched the aerial of the car. Maybe the unit needs a reflash? Thanks in advance.


Failing that anyone in the UK got one for sale. This one could be used for spare parts if anyone needs any.
