Re: Lenovo Y50-70 Screen Flickering

after a few months of having my laptop my screen started flickering and blinking, also get horizontal lines going across the screen. i have never dropped, bumped or in anyway damaged my laptop, i have also updated drivers for the gpu which had no effect. i then  left the country for a year so no way to send it back in time for warranty. phoned them up today and they refuse to fix my problem. everyone is having the same problem with this laptop. it should be a factory recall. i see they recalled other products maybe they to busy with those >:(.. still sucks though cus a new screen is expensive ontop of an already pricey laptop. wont make the mistake of buying another lenovo product. thanks lenovo

So I fixed it on my laptop after many months of frustration, and it turned out to be a connection issue between the display and the laptop board. The fix was rather simple.

 

First I had to open up the laptop display panel, which was as easy as slipping the file from some finger nail clippers between the plastic panel and the metal backing on the display. Shown here:

 

I don't know if this helps anyone else out, but after months of frustration, I narrowed it all down to this flimsy connection and after reconnecting it and putting some folded electrical tape to support that flimsy connection behind it, it now has absolutely no flickering.

 

I just thought I'd post what I did in the hopes that it may help others out.

I tried everything. Seriously everything. I tried the BIOS update, different Intel HD graphics updates. Msconfig stuff and much more. Still the blinking is not gone. It drives me crazy, I bought this laptop for 1349 Euro and within a year the screen starts blinking. It's the first time I'm trying a windows laptop instead of a Macbook. Most stupid idea ever. 
Everything is much more complicated.

If it's a hardware problem, then give a solution! What do i need to do to solve it?

Send it in for repairs. Could be a faulty connection or even gpu damage (probably overheating for too long)

Hello all,

I think that all of these problems with flicker are connected with cpu usuage/speed. I've tried using throttlestop and I observed, that if I locked cpu speed (using multiplier lock) to above specific limit (for me is from example 3ghz), the screen goes crazy, the more speed, the more flickering occurs. I have a theory about why resetting wire to lcd panel helps. It helps me too for short amount of time (few days) and problem returns. I might that connection is not a problem. Simply touching this wire solve the problem, so there may be problem with grounding this wire or something. Look at this metallic shield covering whole cable. It maybe must be grounded somewhere.

Regards.
