Re: Issues with Bauer XT37

ok guys got the voltages from the PSU to the main board with both tv on standby and switched on, also tested voltages to the inverter and got no voltage.

(TV IN STANDBY)

12v 0.67v
12v 0.67v
GND
GND
+5v 4.97v
GND
on/off 0v

(SWITCHED ON)

12v 0.39v
12v 0.39v
GND
GND
+5v 4.97v
GND
on/off 4.12v

why is the voltage dropping when tv is switched on ??

Re: Issues with Bauer XT37

The ON/OFF is turning on, so that is good.

As for why it is dropping -- my guess is 0.6V there is from leakage and not from 12V output, and not something to worry about.

Re: Issues with Bauer XT37

If you want to know the useless answer, the lack of the 12V and 24V is what is causing the TV to not display an image, and otherwise function like a TV should do.

As for WHY exactly, it probably has a lot to do with that blown fuse you replaced: likely something's still bad on the PSU. Clear and IN FOCUS pictures WILL be necessary, top and bottom side. We should be able to read the ref-des (R122, Q878 etc.etc.) If necessary break the picture taking down into four or more parts.
