I have found that disconnecting and reconnecting these cables can resolve
many of the issues. Whether this because of oxide buildup on the
connectors, and the plugging scrapes this off, or just the cleaning out of
gunk in the process of opening up is the cure I cant really say.
If you have a Repair Cafe or Restart Cafe in your area this is a good place
to take this sort of problem, If there isent any perhaps you should
consider starting one up.

Fwiw, I've found this is often a sign of the screen inverter getting close
to failing.
For any of these parts the standard place to source then is eBay in my
experience.

Hi,
I recently discovered that my (4 year old) laptop's LCD display panel
flickers when the lid is opened/closed. When the panel is not moving, it
does not flicker.
I realize this is slightly OT, since it is hardware, rather than Linux
related, however, I hope you don't mind me asking since local knowledge
may help.
I am fairly sure that the cable connecting the panel to the motherboard
is beginning to fail. I have the service manual for this model and can
see the exact part number for the cable, which is separate to the panel
itself.
However, since the laptop is an old obscure rebranded Clevo model (it
was original from Novatech), it seems unlikely that I will be able to
find this exact part (I have searched).
I have two questions:
1. Has anyone here replaced the LVDS cable in a laptop before? If so,
how were you able to locate the correct part?
2. Do you know of any local computer repair companies who may be able to
source a suitable part and complete the repair on my behalf (for a
reasonable fee)?
Many thanks for reading,
James

Thanks. Sadly the flicker has returned. It's really intermittent, though.
My understanding is that, if the inverter is failing, then the backlight
have issues. In my case, the flickering is corruption of the image, but
the backlight remains lit, which makes me think that the issue is with
the data transmission to the screen.

Hi James
Sounds like you have a faulty lvds cable. Wouldn't be a faulty inverter,
as a 4 year old laptop wouldn't use one of those. Modern laptops use leds
to backlight the screen.
Other faulty components collect be: lcd screen, led backlights inside the
screen or GPU.
As someone who runs a laptop repair business, I would say you need a
replacement lvds cable.
I have experience in finding even the most hard to find parts.
If you want help finding the right part for your laptop, contact me off
list.
Regards
