Help me to unbrick my MK802 IV !!

[Giatzo]

Hello there,
I'm new in this forum and any help will be very appreciated. I have a MK802 IV (AP6210 version) bought one month ago and it worked for 20 days, but now it can't boot. My TV show "no signal". This is what I did:

- I've upgraded with the new official firmware from Rikomagic and everything was fine
- I did the antenna mod suggested from Rikomagic and everything was ok, the wifi reception has been slightly improved
- Then I flashed an official ROM mod from Kasty and I used it everyday. The only problem that I encountered was that when I wanted to shutdown the minipc via software I needed to reboot it (by plugging and unplugging the Power Supply) two times to get it work.
- After 20 days more or less i wasn't able to boot it, it rebooted automatically after a couple of seconds and then only "no signal" neither the Rikomagic logo.

Of course I tried to restore the firmware, and, even if the firmware upgrade process is ok, i get no video. With the NeoMode 1.3 ROM I'm able to see something on my TV, but when the Android robot appears and it begins to decompress all apk files it reboots.

I think it is the RAM corrupted.

Any suggestion?

Thanks

I give it back to the vendor to use my warranty. I used it only for 20 days and I hope next would be better!
