Hello All,
I'm a hobbyist at best, I've built a few radio kits (I'm a Ham), but other than that I'm a newbie at electronics.
A friend gave me a Samsung UN60EH6003 that works about 50% of the time. Specifically, it demonstrates the common Samsung dreaded dead screen and blinking standby light when you try to turn it on. To be more specific, 50% of the time when you press the power button it starts normally, 50% of the time when you press it the screen does not come on, there is no startup tune sounded, and the red standby light blinks slowly.

Hi!
I have a weird one for you. I have a H87-Pro4 from Asrock that power cycles. But only when you do a restart after it was already running!
Symptoms in detail:- I switch off the ATX PSU for ~15-20 seconds, then switch it back on again.
- I press power button. The board boots without issues.
- I can shut down the board any way I want (via OS* menu, or pushing the power button - either in the OS or the boot manager).
- Push power button again, board boots fine.
- This shutdown/powerup can be repeated multiple times without problems.
- BUT: If I do a restart instead

This camera was flashed by the owner and after update it starts displaying NAVITEL and that is all.
I have contacted Navitel help , they sent me one file called SdFwCode.bin and the firmware SD_CarDV.bin which i have uploaded here in a zip file together with a backup of the actual dump thats on the camera.
These two bin files they say that i have to copy into an microsd card formated fat32 not bigger then 32Gb and to install the card into the camera.
So first i had to press the M button on the camera , while keep pressing it i have to plug power cable into camera then press...
