If I take the processor out, see what the laptop doing to video:

The problem is the processor or motherboard?I tried with another processor (T4500) but does exact the same problem.

The processor who have the laptop is T2330.

CPU core Voltace (C1) is exactly 1.085 Volt.

Laptop model is:



Please help me!!!

So you told us nothing, showed us nothing.
Lets start again, what happens when you turn on the Laptop, does it charge etc. More infos, these videos are very bad filmed with no infos at all.

Sorry for the rushed video...The laptop is charging normally ...Just do not open at all...Flashes momentary leds and screen is constantly black...If I take out the processor, light while constant leds and then turn off ...screen is constantly black

That laptop has the G86-703-A2, its most likely a bad GPU. Reflow it and report back.

It does not have GPU chip.It have CPU, le82gl960 northbridge chipset and nh82801hbm southbridge chipset.

Re: Need help with one LG E500 laptop

check for short on black capacitors neat cpu and chipset. most the 2 on upper left of le82gl960

post results

check also cpu coils resistance with and without cpu.

dunno if t2330 is compatible with t4500.

Coils resistance is 1.6 Ohm with and without CPU...

To measure capacitors they must be unsolder them?

Re: Need help with one LG E500 laptop

just misure if shorted or not

Re: Need help with one LG E500 laptop

as first desolder joint or unsolder coil to see in which part of circuit u have short

Re: Need help with one LG E500 laptop

Whith mu multimeter i can not understand if I have a short at capacitors...I'd give me a friend one capacitive meter device and check them.....

Hello,

You can use your multimeter in order to measure if a capacitor is shorted. You measure its resistance and if it is near 0 it's shorted. I think that you don't have a shorted part if the laptop powers on. Try a light reflow on that southbridge.
