Re: MSI U250 no diaplay

I am pretty sure it is a NB problem, but you can try your luck.Comment

Re: MSI U250 no diaplay
Have you tried an external monitor or a known working lcd screen? I would try all the basic stuff first.Comment

Re: MSI U250 no diaplay
Altough it's U230, the main problem is still the same - IGP AMD, RS780 in this case, so reball or change 216-0674026. You should do that long ago.Comment

Hi:
i am trying to repair this Christmas lights from my parents. They are incandescent lights, no led lights.
I have tried with 12V a 24V small lights that I found in Aliexpress but is obvious that are not the right ones. They last microseconds connected. Do they blow because of Amps or Volts?
If I measure the Amps in the string........it's only 90mA. If I measure the Volts in the "green box"......it's between 0 and 190V, but doing a little bit of maths from the number of bulbs in series.......it's only about 6V per lamp.

Hello,
I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.
Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,... -
Does not turn on, lights 3 of the 4 LEDs and turns off and stays like this, presses the power and repeats.
I saw that the room LED lights up only when the screen is connected, so quiet.
We have all the power supplies, even processor, 1.8V
One thing I found strange, it has a very low resistance in the Vcore is giving 1 Ohm , work with notes and such, I know that this is normal in some processors but with this resistance only take video card so found it strange.
I suspect that there may be some leak in the processor.
Anyway, when I press the power, it... -
