HP L1706 alternating colors with or without signal

[eddiesomesan]

Hello. I am working on a HP L1706 LCD.
The problem with it is, when I power it up, on the whole screen appears a color which is changing to another after few seconds and so on. So on the LCD there are some alternating colors like some kind of a test mode. Tried it plugged in and even without the signal cord I have the same problem. Everything looks good inside.
A few months ago I have recapped the ps zone and it worked great until now.
Any sugestion is appreciated.
Thank you.

Check if the LVDS cable is properly connected.
