![]() How are you measuring the temperatures? Its unlikely something would be 80c next to 42c due to conduction.

![]() As you've found out they aren't so accurate if shone onto a reflective surface. Put a piece of matt tape on the area you want to measure and move the 111gun away slighlty as per the instructions.

![]() thank you for the answer diif but is it normal with different values on the same chip,I try to find the short on that TV and I happen to put a finger on the mainboard cooling protection in the middle and felt that it was a little warmer I pulled it off and found that value. I will try with your instruction but what is the purpose of putting the tape on the area you want to measure? do that not decrease the value?

![]() As I have already written it is highly unlikely to have a difference of 30c on a processor or anything small. It's measuring inaccurately due to the reflective surface and also its far too close.

![]() Aha ok I have misunderstood your explanation, can you say how far from the chip is the right distance? I will measure with TM-902c to see the difference even if the feeling of the fingers is not so bad
