Beovision 7-40 MKI LCD panel defective?

Hi again,

To add information to my post, I have measured voltages on the power supply board. If I understand correctly they are all present: around +400VDC on the main capacitor, as well +23VDC, +23VDC and +5VDC on the stand-by supply…

Hello joupar, I do also think that a repair is the most elegant way, but if you cannot find the issue or a replacement panel, you could maybe find a fully working MkI for little money. It will depend a bit where you live I reckon. Also that panel will be old, so it is a chance, but it could be a cheap way to get a working TV (for now) again. Also a good chance to get an extra Beo4, a higher/lower/wall stand,  another  BeoLab 7. Here in the Netherlands they come very cheap as they are heavy and people want them to be picked up. Just an idea! Regards, Johan

Hi!

I have as a hobby to fix electronic devices. I got this Beovision 7-40 as a freebie from a lady with whom it had sat years without any use. And I think I now know why it was so…
