Resistor ID help. Discolored from heat.
It is hard to determine the colors on these resistors. The small one in the lower left measures 10k. Next one up measures 33.1k.
Over to the right the lower discolored one measures 1.5k and the one above it measures 32.4

Best describe the equipment, and get a schematic, which you can post.
Cracked transistor is bad news. A sign of catastrophic failure at times..
So please describe the fault that made you start the repair as well.

In terms of reading the resistor values usually the leftmost band will be spaced a little further apart than the other 4 bands. Sometimes it can be hard to tell.Do you know which is the right side and which is the left side in the attached picture?
They also are not all oriented in the same direction.
One of the transistors has a huge crack in it if I am not seeing things. I would look for other fried semiconductors as well.

The fault could be elsewhere in the circuit, drawing excessive current,
and damaging some of these parts. Start with checking the power supply.

Thanks for the input on this. I will do some more testing coming up.
I will probably do a separate thread about the symptoms, and faulty components that are found.
I ordered some transistors to replace the cracked one a few days ago; for some reason it is shorted out. hehe. Those are MPS8599 and MPS8099.

the guy referred to the left-right side of image...not resistors, and the next up from bottom left was the 1.5k not 33.1k...In terms of reading the resistor values usually the leftmost band
