Having fixed it once already I have now managed to kill it once again, this time i was slotting it into the case and caught two of the SMD's on the back and knocked them off.

 

Anyone know what they are as I can't seem to find them anywhere in my case, they seem to have vanished, so I will just order some from rs or farnell.

Thank in advance all

These are resistors. I can measure the resistance for you but measuring in circuit will most likely lead to wrong values.

 

Or you can remove and measure individual resistance :P

Thanks for the info der8auer and the offer.

 

Are all the resistors on the back in that area of the same value ?

 

If so I will just remove another one and measure it

 

Is there a specific name for that type and size of resistor I should look for, I'll have a check for one on RS electronics website ?

There is always a pair of two resistors behind each VRM. I guess all in the same line have the same resistance.

 

So all marked with 1 have the same resistance and all marked with 2 have the same resistance. Means you have to remove one pair and check the resistance of each one.

You need to know the size to get the code and the resistance to order.

 

For the code check the table below

 

Rectangular passive components (mostly resistors and capacitors):

01005 (0402 metric): 0.4 mm × 0.2 mm (0.016 in × 0.0079 in)

0201 (0603 metric): 0.6 mm × 0.3 mm (0.024 in × 0.012 in)

0402 (1005 metric): 1.0 mm × 0.5 mm (0.039 in × 0.020 in)

0603 (1608 metric): 1.6 mm × 0.8 mm (0.063 in × 0.031 in)

0805 (2012 metric): 2.0 mm × 1.25 mm (0.079 in × 0.049 in)

1008 (2520 metric): 2.5 mm × 2.0 mm (0.098 in × 0.079 in)

1206 (3216 metric): 3.2 mm × 1.6 mm (0.13 in × 0.063 in)

1210 (3225 metric): 3.2 mm × 2.5 mm (0.13 in × 0.098 in)

1806 (4516 metric): 4.5 mm × 1.6 mm (0.18 in × 0.063 in)

1812 (4532 metric): 4.5 mm × 3.2 mm (0.18 in × 0.13 in)

2010 (5025 metric): 5.0 mm × 2.5 mm (0.20 in × 0.098 in)

2512 (6332 metric): 6.4 mm × 3.2 mm (0.25 in × 0.13 in)

2920: 7.4 mm × 5.1 mm (0.29 in × 0.20 in)

Awesome, I will break out the heated tweezers tonight probably and get a couple off and measure them.

 

Really appreciate that der8auer
