Ok, I'm a newb so please take it easy on me. The long silver bar in the center of this picture is a fuse? If not can you please tell me what component it is..

Re: Quick Question It may sound stupid but please respond.
No, it's a crystal oscillator: http://en.wikipedia.org/wiki/Crystal_oscillator
It generates the clock the processor near it uses for its frequency.
There's no fuse in the picture. Post a photo of the whole board.
The fuse may (or may not) be towards the left side, as the blue round things are inductors, which are commonly used in the power supply section of the board, so naturally the fuse would be at the start of the power supply area.
Post the whole board picture and we may be able to help you out further. -
Re: Quick Question It may sound stupid but please respond.
Here is the picture as requested. I tested all the voltages off of the power supply and everything checks out. I proceeded to test mosfets and am getting no voltage to the one in the upper right corner of the heat sink for the processor. This is for an insignia ns-lcd47hd tv. I turn the power on, light goes blue and nothing else. Shut it off and it blinks red 14 times.Attached FilesComment

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... -
Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
Hello to the forum.
My name is Christos, I am new to the forum here and i am posting from Greece.
So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.
To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.
So i tried asking for a schematic from the company and they would not give me one. Instead they... -
