Hi guys... I have an 3yr old 4214... that has started to power it's self off, for no reason. The power on switch is flashing amber. I normal fix this by switching the screen off for 30 secs, then power back on ok.. This prob works for a few hours, then back to the flashing amber light again. First thought it could be fuses or spikes, but i have changed all the plugs & put in an surge protector. Any ideas???... or contacts for an repair place for them to check... Thanks for the info guys!!!
