That is true, but I have not seen a speaker on your motherboard...
Also, I noticed that the 3.3V led on your motherboard diagnostics board didn't light... Maybe you should check the 3.3V line...

Are you using a graphic card, right?
Are you sure this card is working OK?
The fact the processor is heating is a good thing. It means that the tension there is ok.Leave a comment:

I got it
If the coil is overheating, it means that there's an exceeded voltage across it. Do you have the schematics of this laptop on hand? You need to investigate the normal tension for this coil and why the tension is above the normal level.Leave a comment:

Thanks for replying!
I tested the continuity of the flat cable using the multimeter on the diode scale and it is OK. One thing I noticed is that the notebook does not display video on the external monitor either, but on the other hand the keyboard responds to the num lock and caps lock commands, indicating that the system has booted...
Any ideas?...Leave a comment:

HP compaq NC6400, LA-2952P, white screen
good morning
I've had this laptop sitting at home for many years with this defect, and now I have some free time and I'd like to fix it.
9 years ago I tried to sell it to a woman, she kept it at her house for a few days and then returned it to me broken (hinge). I bought the hinge and a new flat, thinking the problem was in the flat, and it wasn't...
The screen connector part is in the photo below, I measured the voltages with a simple multimeter and the measurements were as follows:
1: 1,3V
2: 1,2V
4: 1,3V
5: 1,3V...
No activity results to display
