Re: Another G72 - 120SD with black screen
Any luck? I have the same problem. After showing some distortion in picture through hdmi connection it refuses to start. Just the power led on but nothing else. Did a quick reflow on the graphics chip but still nothing.

Re: PS4 HDMI Issue
I fixed one the other day. Just the HDMI port was broken. It is not easy you need to do it a couple of times and set your technique!Leave a comment:

Re: Samsung NP350E5C sometimes opens after 2 minutes of no screen
Did both the chips with your cleared files. Now I get a reboot loop. Starts and shuts off and again the same. Noticed that pins 7 and 8 got shorted on the mainboard cause of the heating cycles... I do not think that causes any problem check schematics please

Re: Samsung NP350E5C sometimes opens after 2 minutes of no screen
Got the programmer but I do not like its quality and has very little options on chips numbers. However I managed to program one eeprom MXIC MX25L1605D but same symptoms applies and not even booting once. At least before it booted after 6-8 times...Leave a comment:

Re: Samsung NP350E5C sometimes opens after 2 minutes of no screen
Yes you are right my Bios chip is also 25LC...Bought it for airbag reset but proved useless. I ordered a TVP2588U+ Bios Programmer locally so it arrives faster. Should I reprogram both chips?Leave a comment:

Re: Samsung NP350E5C sometimes opens after 2 minutes of no screen
Are the updates able to distort the BIos chip?? Wow...
One idea came to mind. I have a carprog lying around with 4 pin soic clip! Can I use it? How to identify the EEPROM chip code?...Last edited by Dimitrios; 12-06-2017, 01:40 AM.Leave a comment:

Re: Samsung NP350E5C sometimes opens after 2 minutes of no screen
Hmm yeah thats what I am thinking. I mean I tried to do a BIOS flash from Windows downloading the latest flash utility but was stuck at reading bios and then freezing... I guess I will buy that programmer after all. Should have done that sooner... I wonder if that indeed fixes the problem!Leave a comment:

Samsung NP350E5C sometimes opens after 2 minutes of no screen
Hello friends! I am an experienced tech but have never seen that kind of behavior. A laptop came for regular checkup and maybe a new disk complaining also for wifi shutting down many times. I formated it with windows 10 and got it updated fully and all good. Gave it to client only to get it back after 2 days. I tried to test it but after rebooting sometimes it got stuck with this unusual problem.
It sometimes opens after 2 minutes of no screen at all properly on Windows. I can restart it properly but if I press shutdown it refuses to start or it gives a complete black screen no light nothing... -
Re: PS4 HDMI Issue
Just finished a repair like yours, my first actually. After putting new HDMI port had the same issue as before fixing being the immediate powering off. I also put some big washers on the screws and voila. Led light stays on and white but NO picture coming from HDMI, pity... Wonder what to do next...Leave a comment:
