Hi Doug

It looks to me like the set is in some kind of 'burn in' mode'

Do you know how to access the service mode and carry out a service reset?

Hi all, Thanks for your input. I've found service menu (display>p.mode>s.mode>sleep) but can't find any reference to factory reset

Hi all, Found a dvb panel on internet for a tenner. Problem solved, but I'd still like to know what causes such a 'fault' Doug.

Hi Doug,

Don't think you mentioned set model or DVB panel numbers - sounds like an old Vestel - Chris.

This sounds to me like the panel is not receiving a signal.

Once, when working on a set I accidentaly powered it up with the lvds connector partly unplugged, and the panel went through a sequence or red, green, blue then colour bars.

Hi,
Check if this is shown on the service menu:
'E2P INT', this option initialises the EEPROM,
Regards,
John
