You can have a competent electrician wire in a new panel of similar size inside the BV-7. There is enough space inside it to accomodate any newer LCD panel. It does not have to be B&O. Save the TV.

This is a good approach, but.. how to find a compatible panel anyhow? I can find the technical competence, but I'm assuming the signal will go to it - internally on the BV7 - not using a standard HDMI signal so some custom wiring on the switch board of the TV is required.

I think I cannot just get a 40 inch Samsung TV and fit it in.

Any seller suggested for the panel, if you trust those exists?

Panels are never from B&O, this is known.

Maybe B&O has a wiring schematic for service centers that you may be able to get a copy of? Theoretically, you can get an inexpensive 40-inch panel out of a newer LCD television and have it modified to fit inside of the BV-7 cabinet. Once properly connected, the BeoSystem should work with is like the old panel you replaced.

Good morning,

In the service manual section of Beoworld, there are the service manuals of BV-7 Mk III and Mk IV where wiring diagrams are shown. Basically, these TVs have a complete Beosystem 3 inside and the communication between the video processor board and the panel is done with an internal DVI (possibly HDMI for the latest versions of the TVs) connection, There is then a Panel Interface Module (PIM) board that takes the video signal from the internal DVI (or HDMI) connector and translates it to the LVDS format and sends it to the panel. The backlight signal generation and frequency doubling (if the panel operates at 100 or 120 hz) are also done by this board. 

The solution is then to find a raw panel that is compatible to the one installed in the TV. You can find the model of panel used in the service menu of the TV. These are all Samsung panels. One important point to check for the replacement panel are the power supply voltages.

I own a BV7 MkIII TV and it still works well after 11 years but I realise that I will have probably to repair it myself if problems with the panel occurs in the future. 

Good luck,

Jean

As additional information, if you succeed in finding a compatible panel, the colors will probably have to be recalibrated by changing the values in the service menus.

Good luck,

Jean
