Haier L32D1120 Blue light and nada

[CraigR]

Haier L32D1120 and as soon as plugged in I get the blue light on steady on the front. Pushing the power button or any others do not do anything. The blue light stays on steady. I read U11 is a common problem for this set when it's dead so I replaced it but still get the same results. No backlight flash or anything but a steady blue light. A visual inspection under magnifications shows no bad caps or cracked solder joints. Not sure where to go.

Perhaps no-one knows did you read this the boards look same/similar some of the tests may help you - did you test the U11 There are other regulators on there -you should check them all.

UPDATE: I got another used motherboard and now when I first plug it in the blue light comes on for about 5 seconds then goes red. Nothing ever on the screen and none of the buttons do anything.
