sagem tuner problem

[pavlik1]

Hello,

After connecting the cables on the back side, the receiver stop working. The diode BAV99W/A7t was burnt out.
Now the receiver work only if the cable is connected directly to the Tuner.



The Atmel AT76C651 is running at 75 decree!!! is this normal

I am looking for tuner board schematic and RF2312

Just for information, Removing the faulty diode and first capacitor, then connecting the tuner directly to the back connector of the box gives:

excellent signal level
excellent signal to noise ratio
very low error

I am happy with the mod.
