Toshiba laptop, on but nothing on screen, lets fix it

[HerbOldenburg]

Old video - Old laptop - and I was given an old Toshiba with no video - Heated the video processor from the back just as our teacher Sorin did here and bingo - Video is now working - I did have to heat it 2 times. The first time I guess not enough heat. So our teacher indicated pay attention to the heat and heat sink and feel the heat - 2nd time was a charm. I learn something everytime I watch any of your videos and you are a fantastic resource and selfless steward and generous kind individual for sharing your knowledge - thank you again Sir Sorin! Kudos!

I would have liked to watch you do the whole job. You may think it is boring but I think many people could learn tips, tricks, more by watching even routine stuff. If it is boring, the viewer can always skip over parts of the video.

I actually watched the entire video, I was very surprised to see what the problem was, I am running with the same problem now and thanks to you I know what not to mess with, I agree with the other viewers you should do the entire video about how to fix it.
Thank you and I hope you make more videos.
Stay healthy and smart.
Peace

Very impressive teaching how to fix laptop. Thank sir

Nice intermediate tutorial, not for sissies. You did BGA with power on, this tells that you are no novice tech. Thanks, vaio also has this issue, and you are right, AMD = graphic card overheat. Thanks Sir, I have a vaio which has intermittent display when powering, I also suspect the graphic card balls came loose. have to reflux or find another gpu chip from scraps. Subscribing and following.

Great video I have 2 Toshiba old L300 with same problem, turns on but no display, so it the graphics chip.

This malfunction is actually cause by a defect from the factory and will take time before they are actually noticed. To fix it you need to reflow both north and south bridge on both sides of the board. To fix the heating issue you need to take off the cooling vent and blow some air from a can of compressed air and apply new themal paste as the compound would have dried out cause poor thermal distribution to the cool fan.

I think this is the same case which is i also face, but my laptop is toshiba satellite L55-b5267 i'm using it only by charger not battery there is is light when i plug there is power but noting on the display and also if if it help there is no power transfer to the fan which doesn't spin also, ....thank you for all kind of your support

[ariffnazari]

A beginner -
I went through all your lesson. My laptop Toshiba satellite L740D wont turn on after hibernation. I did everything but only the light turned on.

[naomismit]

Good day. I have a HP 630 the fan spins for about a minute and goes off. No display. When I touch (press a little) on the power connector then the fan spins very fast but still no display. What could the issue be? I have been watching probably all your videos I have learnt alot. But this is a serious head scratcher. No components are getting hot. No caps lights are blinking. Ram I changed and cleaned. CMOS battery is fine. I am watching this video regardinf the graphics chip.

You're the best repair tech guy on here and there's no one can compare to you. Btw, what's the name of your other shop? I'd like to watch both of your shop on YouTube. I wish you located in US 🇺🇸. If i sign up with the best plan you have for $15/month, do i see your trick and tips videos? Your quick responding is appreciated.

[edwardtsema]

I have an Asus Aspire motherboard. It has the AMD Vision graphics and I have the same problem. It powers on but screen does not turn on. The heatsink has some corrosion on it. Bad heatsink made the graphics chip fail. Thanks Sorin for advice!

[kylequerijero]

[abdullahshammaa]

Dear Sir.
I would like to thank you for your help in repairing Laptops and sharing your knowledge with us. my problem started when I interchanged two HDs one from Toshiba Tecra R940 with another from Compaq Presario C700.
First both laptops worked fine for a couple of days . Then, both stopped together.
When powering ON, the LED and sometimes fans turned ON and the LED stayed ON but nothing is displayed on the screens. I tried several times to get them on again but nothing changed. I am asking your help.

[evancenyaki]

Nice tutorial btw..
