A photo would be better (I mean, a CLEAR photo would be better). I don't know what your square boxes are. The first one doesn't look like any resistor that I have seen. The second one, save for the two square boxes, would be a 33 ohm resistor (two significant digits of "3" with the number of trailing zeros at 0).

Good Morning.

Have a look at SMD Resistors Code, please. They have very examples of SMD coding. Ah, yes. The first one I did read as 70Ω, albeit the rectangles. But, case they are not burned, a multimeter did serve to corroborate.

But the codes shown don't list a 2 digit code. I still don't know what the 71 device is (albeit, it does LOOK like a resistor). 70 is not even a standard value for 5% resistors. Maybe the OP could measure the value with a multimeter.

I think something like 0x4 and 71 on resistor. Maybe 0 is 10x ("0" 4 is 10000 ohms right? if 10x10x10x10x71 = 710,000 ohms right? I try to find if correct or not.

It's possible that the markings are "house" markings - a marking unrelated to the value, more or less the part number in a design. ICs are often marked this way to help keep a design from being copied.
