is the backlight on?
you can see some brightness on front when the set is on.

or from the backside it is possible to see that the backlight is on.
if there is no backlight at all, you have to check the inverters.
these are part of the LCD-panel. These panels are replaced completely and send back to philips.

Hi Hansje
When i take the connector plug off the power board and plug it back in, the inverter powers up for about a second and then they go off.
There is a small amount of buzzing beforeb this happens.
Do you think it mayt be a power suppy faut to the inverter.
As i say sometimes the tv powers up with the a screen full of vertica lines and other times the standby ight wi go red and no picture at all.
Apparantly there is a fix on the euras tv engineers site but i do not have membership to the site.

Any Ideas?
