I have a Sanyo 19” t.v., model DP19648 and even after adjusting brightness, the picture is darker and darker.
"m bielk sounds like a backlight issue. Remove the back of your TV and post some images of your boards. Use this guide Adding images to an existing question for that. It will allow us to see what you see.
Check for leaking or domed capacitors or any other obviously damaged components. Measure the voltage on connector K8B pins 8 &9. let us know what you get."
