Re: Asus la-7322p white screen problem
What is the voltage on pin # 28 (DISPOFF#) of the LVDS connector ?
Voltage on pins # 1-2-3 (B+) of the LVDS connector ?

I have this laptop showing white screen as soon as I push the power button, it is booting the operating system because I can hear the windows 11 intro sound. If I connect an external LCD with HDMI cable there is no image. Is it possible to hardware disable the AMD gpu in any way? Or any hint?
Thanks in advance -
As per subject, on power up display shows no image, but white
flickering screen. Strangely, it only happen after power was lost
when it was on. After power returns - white screen only, but if
disconnect power for 12-24 hrs, and connect then again monitor
works normally.
Any clues how to go about it would be greatly appreciated. -
I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?
If anyone has any information on the subject... -
I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.
Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.
Then each time... -
Another TV topic!!
I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.
The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.
Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...
