Samsung LCD Model LN55C650
Just ran across this Tv... When you turn it on it makes the little sound, and flashes red 5 times like it is coming on... No video.... After the 5 flashes and the sound the tv is still powered up it seems but no light at all after the 5 flashes.... When you turn it off ' you hear the sound it makes again, then the light stays red....

Hi, I have a Samsung UE50TU with:

Just picked up an iMac powerpc for $1 at auction. changed pram. This is working. Problem, barely any sound. I have everything cranked up in software, reset nvram/pram - nada. I do get sound ONLY if I plug in a powered speakers in headphone port. I do not get the startup bong.
I get almost no sound with normal headphones. I mean, you can barely hear it. Took the board out and by eye found these 2 inductors broken. Not sure if they are for sound. Speaker is also plugged in and I tried a normal pc speaker in its place - still zilch. Are these inductors the culprit?
I cannot find any schematics... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
Hi everyone, I have a Samsung NP750QFG-KA3DE , MainBoard VESTA3-15 BA92-24515A
the battery is charged. pressing the power button the blue LED flashes 3 times and then stays blue. then the sequence repeats.
the fan does not start.
I noticed that I have no power on the processor and it does not heat up. could it depend on the bios?
any advice on what to check? -
Hello, TV has a cracking sound from the speakers, sound from the headphone jack is ok.
with new speakers the sound is just as bad.
UE55D6200
BN44-00457A Power Board
BN41-01587E Mainboard
What exactly can I check, what could be the cause?
How do I repair the error?
I can't find a circuit diagram on the internet
thanks greetings from austria
