Does anyone know the value of theese ??

Im guessing they are a 3.3K resistor ..

Just wondering if thats correct Since they got hot and faded the color bands a lil..

They are measuring 2.766K out of the board So im just gonna replace them

Hi,
It look like orange orange brown = 330 ohms

 

[S Merlington]

They look more red than brown thats why im wondering

Hi,
Check them with am ohmeter. You have 4 the same value. All 4 can not be bad.

 

[S Merlington]

All 4 read different 1 measures 1k another one measures 2k one measure 2.7 k one reads 2.5k they are all bad evryone of them got very hot at some point on both driverboards..

Hi,
Sometime to get a good reading you need to lift one of the leg from the circuit.

 

[S Merlington]

They are all out of the board right now and still get the same readings ANd i know my meter works 100% since i tested brand new resistors and they all check dead on

What do the resistors measure on the other driver board?

 

[tauro0221]

Hi,
Also do not forget to check the power transistors. You may have a shorted
transistor to blown 4 resistors or heated them up.

 

[S Merlington]

They all measure the same as the first driverboard If you look at the backside of both driverboards thoose resistors got so hot they unsolderd themselfs from the board and made the driverboard black where they sit

I don't have any good photos of that driver board but if this is the same board, they're 3.3k.
