R61 LCD with flicker line

Hello

 

I have an R61 7733-3GG with an 14.1" monitor. About a year ago it started occasionally flickering at the bottom of the screen. It didn't bother me much, but now there's a permanent green/purple line at the bottom and it seems to be spreading around line. Here's how it looks:

So my question is: what is the problem? Which part has to be changed? How hard is it to do?

 

And which part would fit? Can I get a new screen that supports a higher resolution (currently max is 1280x800) without too much trouble?

 

 

Hope you can help :-)

Re: R61 LCD with flicker line

Hi and welcome to the forums, toblund. Does the problem occur on an external LCD? What GPU does your R61 have?

Re: R61 LCD with flicker line

Hi, thank you.

 

No the problem doesn't occur on an external LCD. So I figure something must be wrong with the actual LCD display or maybe the backlight?

 

I don't know exactly what GPU it has, in Windows Device Manager, under Display Adapters it says "Mobil Intel 965 Express Chipset family".

 

I'm thinking I will need a new LCD - it seems like a hardware error. But I'm having a hard time finding out what part(s) to get and where to get it.

Re: R61 LCD with flicker line

It does sound like the LCD is the problem. However, it's only an educated guess based on previous experiences. You can find out what part you need and how to replace it by looking at the hardware maintenance manual for your R61. You can get it right here: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-677604

Re: R61 LCD with flicker line

Ok, so I found the HW manual - thank you :-)

 

I looked in the "Parts list" section and found there are two kinds of LCDs. One is WXGA and one is WXGA+ with a higher resolution. I figure it would be really nice if I could get a WXGA+ instead of my old one. But I'm not sure if it will fit. There's a bunch of models listed. On the first type, the WXGA, I think I found my model nr.:

 

It says 7733-CTO, *a lot of xxx*, 3Gx

 

And I figure 3Gx means its good for me :-)

 

But on the second type, WXGA+, I can only find:

 

7733-CTO, and then not the 3Gx, but there are others listed. So I guess it means it wont fit for my model. But I'm not sure and it would be sad to miss the opportunity for a better resolution. So could you answer this for me?

 

And what does CTO stand for?

Hi toblund,

CTO stands for Customized-to-Order system. Through parts lookup site you can find out the FRU number of LCD which came with your unit:- http://support.lenovo.com/en_US/product-and-parts/partsLookup.page

 

Hope this helps.

Re: R61 LCD with flicker line

Hi toblund, it should be okay to upgrade to a WXGA+. The display cables are interchangeable.

Re: R61 LCD with flicker line

Sorry I meant to say that the display cable is intercompatible.
