Guys..... I like to ask sumthing ....do you guys know how to check shorted component? like IC, MOSFET, CAPS, Resistor,thymister......oh yar....i had a resistor on the Samsung SyncMaster 530V ..when i looked at the colour code its supposed to be 3 Mohm....when i tested it with 100Kohm.....it stays at the infinite....even tested all ( 1x,10x,100x,1Kx,10Kx,100Kx)

Re: How to check the electrtonic wheter have short or not ....
If a component has shorted, the resistance across the terminals should be very close to zero on the most sensitive range (1x in your case). If a component has a short, there is direct electrical contact where there should not be. That is it acts like a piece of wire rather than what you want it to be (be that a resistor, transistor, capacitor etc.).
The reason why you are getting infinite resistance when measuring the resistance of that resistor is because the range or sensitivity of your multimeter does not go all the way up to 3Mohm. To measure the resistance of that resistor you need to use a multimeter which has a 1Mx range. Essentially a MOhm range.
However it could well be that your resistor does have infinite resistance (it is an open component) and needs to be replaced. An open component is a component that has failed and there is no electrical contact where there should be. Most likely the component overheated somehow and has physically cracked. That is the component is physically disconnected from the circuit.
