X555LD i7 Processor Suspicious
Hey!!
I've an ASUS X555LD motherboard with an i7 processor.
Yesterday, when i tested it the first time the processor went very hot, i had to disconnect it from the power supply.
I took back the heatsink, later I made another test, and I saw that the processor wasn't heating so much (i couldn't see that there was a small area of the proccesor that continued heating, which I saw later).
Hoping that the processor weren't the problem i continued exploring the motherboard. I thought that it could be a BIOS problem, so I looked for the VCC signal of the bios chip, and i didn't...

Re: Samsung NP300E5A-A05ES doesn't start
I've been investigating the lost voltage and i've found that there are 4 mosfet which have it's VGS=0V. I've also checked the RAM voltage obtaining 0.25V.
I've checked the mosfet controller and I've found that I've correct supply values on the controller (VR_ON, activation pin is 3.03V, VDD supply pin is at 5V, VCCP also is at 5V)
There are two pins on the controller called PGOODG and PGOOD which would be high for a good operation but the controller puts them at 0V, bescause i've cutted the track on the board, having 3V by the...

Re: Samsung NP300E5A-A05ES doesn't start
I have replaced the SPI memory an reprogrammed the BIOS with the .bin of this laptop and i have the same response, at start i have fan 100% working and any response, i don't have response in the screen and with a external monitor the same result.
Also I've tested the power comsumption and i have 0.2A at 19.2V, i think that the starting cannot be completed.
The processor doesn't get hot and the only response i have is the power off when i press the power off button.Last edited by CasasElectronics; 07-31-2019, 08:30 AM.

Re: Sony KDL37S5600 power error
With the whole tv I have the same response, it seems that the operating system is fully locked, and it doesn't respond to the remote signal.
I have thought two alternatives: or search for the NVM memory and replace it (I don't know where it is located, the component name) or search for a new motherboard.
What do you think?

Re: Sony KDL37S5600 power error
I've tried to enter the TT menu, because i've seen in the manual that i can enter the number 41 to restart the NVM, but i can't do that, i've pressed the three keys to enter the mode during 5 seconds and the red key 2 times before pressing 41, without having any response.
I've tested if the TV responds to the power off pulse of the remote control but it doesn't respond, and I think that the blocking status of it doesn't allow to enter that menu.
I also cannot see anything on the screen because i don't have the t-con.
Thanks a...

Sony KDL37S5600 power error
Hi, a friend has brought me the a sony kdl37s5600 motherboard, which has the problem of 5 pulses blinking red led. Thinking that the issue could be the power supply, I've tested the board with my supply, having the same response.
I've tested all the voltages(supply and dc-dc converters) and all are good at the beginning(because during the red led blinking the voltages disappear).
In my test conditions i dont have the tcon, so i'm testing the motherboard without it.
I've thought that the problem will be in my friend's tcon, because if this board has a test voltage which it's...Last edited by CasasElectronics; 06-27-2019, 10:19 AM.

Samsung NP300E5A-A05ES doesn't start
Hello,
I've a the laptop of the title, the problem which has is that when you power it it starts but the only thing which works is the cooler fan at full speed and the power leds, there isn't response at screen (including VGA or HDMI) or sound.
The voltages seem to be present, and there aren't shorts on the motherboard.
I've seen that it could be a problem in the BIOS, but samsung doesn't give me the BIOS file and the schematic. The problem isn't in the graphics card because it hasn't a dedicated one.
I need help and I would be so grateful if you can...

Re: New Members - please post your introductions here
Hi!
I'm FranCasas from Spain. I'm studying Electrical Engineering in the University of Cordoba, Andalucia. Since I was a child I liked a lot disassembling toys or every electrical thing that I had in my hands.
Years before I decided to study Electronics, because I love that, and from time to time I build homemade speakers that are very appreciated by my friends. Also I like a lot rebuilding and restoring laptops, I have repaired a lot of them, and I like to see that I, with my hands and a lot of patience can make...
