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.

Hi,
I am working on an Asus ROG laptop repair. I was able to find that there is a short on the motherboard, and the 20 volts from the charger only gets to the first mosfet before disappearing.
When looking around with a thermal camera, I noticed the chip marked "14C" in the picture was getting warm. Nothing else was receiving heat.
I found a boardview diagram and schematic for a motherboard that looks nearly identical, that has the same component. This appears to be marked as "AC Short Protection" with a value of 13.7KOhms.

That's now the second time in my repair career that a through hole resistor go short!
it was a Vishay CPF124K900FHB14 1W resistor measuring new 24.9kohm. <- notice the KILO ohm. Well now it measures 28.1 Ohm!
See picture and PDF attached. This is something very rare happening, but apparently it does happen!...

Hello,I need help figuring out the resistance of this exploded resistor. I'm pretty sure it's the one labeled R37. I tried measuring it with a multimeter, but I got different values each time, probably because it's exploded. If you have a schematic, it would be really helpful!
Its a gtx 1060 6gb inno3d compact, i you have schematic it would be very helpful.... -
I have Asus FA506 ( board DA0BKXMB8D0 Rev: D). Can you please roughly indicate what the lowest resistance I should measure on a coil? I know that a low resistance is allowed on coils in CPU or graphic circuits but can you provide acceptable values of resistance?
Thank you. -
Hi guys, i was wondering, i've got 9Ohms on Vmem, one of the mosfet was shortet to ground, so i've desoldered hi and low mosfets nad still low res, then i removed all of the memory chips, and the resistance is still low, so did you had maybe a card with that low res on memories, and the card was working fine ?
Removed the U1866Q and still without result, i dont have thermal cam so can't see where is hot spot when incjeting voltage.
The resistance on core is ok 0.1Ohm ((Power 0.8V when on)
Resistance on 12V 4K ohms (Power present when on)
Resistance on 12V PEX 4K ohms...
