Can you see the multi (grey) horizon lines on the screen moving up and down?: [URL="https://youtu.be/brodSAT0XNA"]https://youtu.be/brodSAT0XNA[/URL]
What is that? I checked all caps are good and brand new HDMI cable.
But I connected the VGA port and looks perfectly.
I checked ripples on all power supply's outputs no ripples voltages.
Any ideas?
Thanks!

SANYO DP19640 back light out...
I have a SANYO DP19640.
When I turn on it did turned on the back light then in few seconds then off the back light but I can bare to see the LCD screen seem working but no light..
I opened back panel and I see the board has built in power supply and inverted together.
See the pictures in attached files.
I checked all caps are good...
I suspecting the two chips something.. Q7004 and IC7001
Any idea where caused the problem with back light? OR anyone have fixed it before?
thanks!... -

Re: DP40142 Power Supply
Alright, first I have to do my own power supply for 5V, 12V, 24V to connect it and to see if other boards are good then get new PSU if not then trash it.
THANK YOU FOR ALL YOUR INPUTS!!!!
