UN46C8000XFXZA Sam song just started flickering do you have any suggestions

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I think that it's likely to be a problem with the power supply board. I would look at it and check the capacitors on it to see if they are OK.

power board is dead.

I always turn off the add my songs to itunes, and i always move the songs to a sorting folder until i retag all the metadata before moving the songs to folders for each genre and then each artist etc. Nothing ever gets lost. Later i can add to itunes library or SAM Audio Broadcaster library (a disc jocky software). You never know if the mp3 rocket folder may be deleted during an uninstall and update. Also you can turn on a add to my itunes library upon download in the settings.

Change speaker settings from headphone to desktop speakers and see if thats not the cure. Let me know : expert-tech / SAM

Could be anything from a bad hand controller cable, LOW battery power, or a blown out hand controller.

Check the cable and the batteries first.

sounds like a cracked head

It may be the door interlock that is faulty. This is the cheaper solution however it maybe the the electonic board. In any case it needs the attention of a bosch Technician. Cross your fingers its the door interlock.

there should be a little switch on the transmission telling your car comp to engage. just replace it!

I had the same problem with my mp3, i fixed mine by. when you load your mp3 player onto your computer try creating a folder name it something like classic, pop, rock, favorites and then try loading your songs into the folder. I can't promise it will work but that works for most mp3s. hope everything works out! good luck, sam
