Y70 screen Flashing

For the past few years I've been having this issue where the screen flashes constantly. In the time it has taken to write this sentence it has flashed about 30 times. It is also flashing thin horizontal lines and a blue bar sometimes flashes on the bottom of the screen covering about 1/5 of the screen. I've had this laptop for a couple years now and it has had this problem since about month 2 or 3. I already sent it in on warranty last year and it still flashes. How can this be fixed? It is literally giving me headaches to use my computer.

 

The only thing that somewhat works is pushing my thumb up against where the screen connects to the rest of the computer. And even then it still flashes.

 

On another note the webcam no longer works. The light turns on but the camera doesn't see anything.

Re: Y70 screen Flashing

In addition to putorjuy`s response,

 

Try to see if you can enable the camera with "FN+F8", this seemed to help a lot of poeple with camera issues as they may have accidentaly disabled it.

 

Also, try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

However, by your description, you say that you can press on part of the machine to somewhat make it work, it sounds like that something may be slightly disconnected, might be wort getting it checked out at a repair shop see if they can see what the issue is, or if you`re confident, open it up yourself.

You can use the hardware manual from the support page.

 

 

Hope this helps, let us know how you get on.

Re: Y70 screen Flashing

Welcome to our club. This has been going on for years. this is a knonw defect on our computers and Lenovo doesn't seem to mind.

I just saw they wiped the 62+ page thread about it. They did it today.

 

Nice, Lenovo. Just nice.

Re: Y70 screen Flashing

Another update: Tried the power holding thing. It didn't work so I tried it again after draining all the power out of the battery. Still didn't work. Taking it in on Monday to see what's up. I'm thinking it might have been a short of some sort?

 

Side note, attaching an external monitor works so I know it's the screen and not the rest of the computer. Thankfully.

Re: Y70 screen Flashing

So something interesting. The touchscreen on my screen still works. I am getting more and more confused.

Re: Y70 screen Flashing

Touch screen is a extra layer above display, so it supposes to work properly. 

It's your display or the hinge of display which was disconnected because of the constant usage (Opening and closing the lid). All this models up to Y700 has an issue with the assambly of this machine, something is wrong with hinge or connector whick fall apart.

Sadly Lenovo doesn't want to give any official reply and claim this falty machines back.

They are even tricky with their international warranty which claims to be available everywhere for a most of models, but in fact they refuse it upon contacting the service.

I'm really frustrated about their behavior and for sure I'm not going to get anything from them anymore
