Please go through the information carefully as my problem is very peculiar and if any expert can give me the solution it will be great helpful for me
6 months back my laptop went blank and it will not boot up despite i get power and all the leds glow but the vidoe doesnt appear and i gave it to laptop service provider and he repaired it and gave me back he said some problem in power section but within 5 days it went blank again and i gave it to him again and after few days he said it is ready and when i went to pick it had the same problem he was himself surprised by the nature of problem and finally he gave up and said it cannot be repaired. i got it back and i thought of giving a try my self i opened compelete laptop tried to warm up the mother board with a hair drier and to my surprise it got the display.
i started using it while using some times the screen will become junk and it will hang but with restart it will come again in anoter 15 days it went blank i tried the same formula again and again till recently i have done like this for more than 10 times and lastly i came to know that it is the video chipset which is faulty and now i just heat up a video chipset it works but i got tired of doing this every time
i request is can any expert give me permanent solution for this who have gone through simillar case
my question is why it works by heating up i still dont understand can any expert clarify me on this
