Did you connect to external monitor over VGA or HDMI

@Mcplslg123 this is not a graphics issue my friend ill tried using external monitor display is good

I still beleive this is a graphics issue. You reflow the graphics chip and test display on internal screen

@mcplslg123 , could a bad resistor at RN46 (0ohm) cause the same issue ,i`m just asking your opinion, i agree with you this case does look like a bad GPU

Before i reflowed im asking an advise for this,beacuse i still believe this is not a graphics issue because when i connect to external display display is nomal and good.only if i connect on internal screen the original have 6multiple display,but when i connected a working screen no image,sometimes screen becomes green,red.please anyone help on this

Could still be GPU issue, sometimes it's good on external display but you won't have image or backlight on internal.
Some laptop won't recognize a non-original display. You'd have to swap the EDID ROM.
Also make sure the LVDS cable is good.

Good display on external monitor does'nt mean its not a bad gpu. Have seen a lots of Hp dv2000 with good display on external monitor and 4-6 split display on internal screen coz of bad gpu.

If you dont want to beleive that, thats your choice but i'll try a mild reflow of gpu first.

Not likely. The display wont split into 4 or 6 figures coz of this Rn

Yes rn46 has nothing to do with it, my mistake.

Re: Acer aspire 4141g internal display problem

but how come if i replaced a good working screen it does not show images?anything than reflow should i replaced first the lvds cable?

Re: Acer aspire 4141g internal display problem

@mcplslg123 i think you are right i tested the original screen to another board it shows good image.does this mild reflow can last longer?

Re: Acer aspire 4141g internal display problem

Try it, then if it doesn`t work do a mild reflow as @mcplslg123 said .

Re: Acer aspire 4141g internal display problem

which is better mild reflow to heat the chip under or upward?

Hardly matters how you reflow as it wont last beyond a couple of days. You need to either change the graphics chip or look for new mb as i've already said.

@mcplslg123 reflowed the graphics still the same issue it gives multiple display and no image on good screen if i replaced
