T60 Screen/LCD gets black after some minutes with a highpitched sound rising and fading
- by Edward De Leau
Just now my T60 screen got "black" (so no display). On my second monitor: no problems so the vga output works.
symptom:
Screen blanks / no display but works on second monitor
steps to reproduce:
- boot
- wait (it does not matter what you do you do not have to login or anything)
- (now the monitor of the laptop slowly begins to make a ssssssssHHHHHHHHHHHHHHHHHWOEOEssssssss noice of about 10 seconds)
- right after the sounds ends the monitor gets black times seem to be the same each time.
software:
installed no new software before/after, running zone alarm and antivirus.
other:
it does not feel hot in any place, there dont seem to be running processes with strange behaviour.
warranty:
out of warranty
what was i doing:
typing text on a website and doing some php coding in a text editor.
Anyone any idea what I can do here other than buy a new laptop? / does it sound familiar to known cases?
update:

and here: "i have that same problem. i replaced the CCRL on mine and it works fine when the screen is not screwed in. once the frame of the LCD screen (metal portion) touches the metal on the laptop which holds the screen the screen goes black. If the metal is touching the screen when you boot up it boots up with it being very dimmly lit.

Hmmm... not handy 3 or 4 months ago I ordered and installed a new fan. Now the LCD. Which does not seem the core isse but some electric issue so it seems replacing the LCD is not the thing todo here.
I have the following question:
If it is not the LCD that needs to be replaced (see other threads) which parts can I order to fix this? Has anyone got any information which could lead me to identify the issue? I have read replacing the "inverter" AND the "backlightning" would that make sense?
