Hi James,

   Know it's obvious, but there is a link with the GU15WDVDT version where mains adaptor causes backlight problems

   All the best - Chris.

Hi, yes on this one it has internal power supply though power supply and inverter on one board, i changed most of the electrolytic caps in psu just a couple i havnt got in so see what happens when they arive and fitted

Turnip:
Hi James,

   Suspecting that Grundig is just a name, and didn't actually make the set, how's about a pic to compare with other Power/Invertor panels - all helps.

   Thanks, Chris.
