Here are some pics. In the middle vertical connector is the 19v that is reading 17.8. Also,, the green power light flashes 18 times then turns solid. That's when the back light comes on.

LG 42lb5d - No Sound - No Display - Backlight is OK

I'v searched and searched and can't find a solution. No visible bad caps. On one of the connectors the 19v pin measures 17.8v I don't know if that would cause this.

No display (or sound) of any kind other than the backlight glow. Anyone got any ideas?

Love this site. Fixed a few tv's already just by reading threads here.

Thank you very much.
