Re: LCD Monitor Sceptre x20wg-naga will go black after 1 sec.
Hi Rtech,ipman and tmcw,
I checked resistance for the two inverter transformers,that shows 621 and 626.
I guess this is Ok(under 3%),right?
But I didn't check CN001 yet.
Look CN001 on pic:
N/F BL 12V GND 5V
. . . . . . .
Is that right?

LCD Monitor Sceptre x20wg-naga will go black after 1 sec.
Hello All,
The LCD Monitor Sceptre x20wg-naga will go black after 1-2 sec. If I turn on
the monitor the screen just stay for few seconds, and then goes away(black)
but power is on. If I turn off and then turn on,the screen come back and goes black again for 1 to 2 sec.

I have searched this forum and got so many good guidance how to fix this problem. But I am new to electronics repair and...
