Dell 3537(la-9982P) No Display
Hi All,
After pressed power button all coils are showing prefer voltages except Vcore. Without power I checked that coil and its not shorted.
Checked pin 121 on kbc and it shows 3.1V at VR ON pin but 0V on Core IC's VR ON(Pin 8)
So I checked that pin without power and it only shows 9 oms with ground.
Is it too low or where I should check ?

Sony MBX-273 No Power(3.3V, 5V Missing)
I have this Sony MBX-273 on my hand. 19V present but no Voltage on 3.3, 5V Coils.
It has a [B]SN608098 [/B]Chip. When I check its pins It shows;
19V on pin 6(VIN)
5.3V on pin 4(EN_LDO)
3.4V on pin 5(VREF3)
1.3V on pin 1(VREF2)
But only 0.46V on pin 7(LDO)
Is this means Chip is gone?

Different screen sizes
Is it possible to replace a LCD or LED screen in different size, without damaging the mobo or screen?
Like replacing a 15.6 LED for a 10 inch one?
