Agree, though in his case shipping may be a problem plus I heard Hytec prices aren't exactly low.

You're right...they're not cheap at all. Every time I get a quote it takes my breath away.
I am afraid that sending board for repair is aout of question . Shiping from Greece ...................... impossible.
Any idea where the problem is?
I don't know where the problem lies but I've had this same problem on the same model. At least I think it's the same problem. The display would boot to the Welcome Screen and then just get stuck there. I doubt anyone will be able to tell you the exact component to replace. But there's some really knowledge folks on here so who knows. Good luck.
Edit: If I remember correct, after a while the screen won't even come on. And it was the main board in my case.
It`s difficult to find the reason.
"Welcome" message on screen is component from panel firmware.
1.Start up from system
2.Backlight from screen is coming up and own panel start up routine starts.
3.Message "Welcome" is coming up
4.after sucessfully communication between main pwb <--> operation panel pwb, screen is changing to "program loading"If there is no communication possible, system will stuck in "Welcome" screen
No you has to look for LEDs, "Memory LED" flashing, "Warning LED" always on, etc.e.g. if memory LED is flashing, maybe HDD ot HDD controlling is faulty.At least it`s very difficult to find broken part on main pwb itself.
Have had diff. reasons for this.
