Hello guys,
I got a faulty Dell monitor with LCD Panel LM270WQ1. The picture flickers, got lines and blur as u can see in the attachments.
No burn marks especially on the motherboard, tcon board and power board (of course since the monitor can be turned on).
I have checked some voltages from the tcon board as below:
VGH 19.5v
VGL -5.92v
From the cof board:
VCOM-R 5.4v
VCOM-R -5.4v
If anyone of you have encounter the issue as titled above and manage get it fixed feel free to share tips and tricks. I think the lcd itself is shorted to ground but any workaround to get it work again?
Many thanks.
